Value:

XEXP(INSN, 7)

XEXP

#define XEXP(RTX, N)

Definition rtl.h:1351

This field is only present on CALL_INSNs.  It holds a chain of EXPR_LIST of
USE, CLOBBER and SET expressions.
  USE expressions list the registers filled with arguments that
are passed to the function.
  CLOBBER expressions document the registers explicitly clobbered
by this CALL_INSN.
  SET expressions say that the return value of the call (the SET_DEST)
is equivalent to a value available before the call (the SET_SRC).
This kind of SET is used when the return value is predictable in
advance.  It is purely an optimisation hint; unlike USEs and CLOBBERs,
it does not affect register liveness.

  Pseudo registers cannot be mentioned in this list.

Create patterns for debug markers.  These and the above abstract
the representation, so that it's easier to get rid of the abuse of
the mode to hold the marker kind.  Other marker types are
envisioned, so a single bit flag won't do; maybe separate RTL codes
wouldn't be a problem.

hard frame pointer and the automatic variables are separated by an amount
that cannot be determined until after register allocation.  We can assume
that in this case ELIMINABLE_REGS will be defined, one action of which
will be to eliminate FRAME_POINTER_REGNUM into HARD_FRAME_POINTER_REGNUM.

◆ SYMBOL_REF_FLAGS

#define SYMBOL_REF_FLAGS ( RTX )

A set of flags on a symbol_ref that are, in some respects, redundant with
information derivable from the tree decl associated with this symbol.
Except that we build a *lot* of SYMBOL_REFs that aren't associated with a
decl.  In some cases this is a bug.  But beyond that, it's nice to cache
this information to avoid recomputing it.  Finally, this allows space for
the target to store more than one bit of information, as with
SYMBOL_REF_FLAG.

◆ for_each_inc_dec_fn

typedef int(* for_each_inc_dec_fn) (rtx mem, rtx op, rtx dest, rtx src, rtx srcoff, void *arg)

Callback for for_each_inc_dec, to process the autoinc operation OP
within MEM that sets DEST to SRC + SRCOFF, or SRC if SRCOFF is
NULL.  The callback is passed the same opaque ARG passed to
for_each_inc_dec.  Return zero to continue looking for other
autoinc operations or any other value to interrupt the traversal and
return that value to the caller of for_each_inc_dec.

◆ rtx_mode_t

typedef std::pair<rtx, machine_mode> rtx_mode_t

This is used to bundle an rtx and a mode together so that the pair
can be used with the wi:: routines.  If we ever put modes into rtx
integer constants, this should go away and then just pass an rtx in.

◆ insn_note

enum insn_note

Codes that appear in the NOTE_KIND field for kinds of notes
that are not line numbers.  These codes are all negative.

Notice that we do not try to use zero here for any of
the special note codes because sometimes the source line
actually can be zero!  This happens (for example) when we
are generating code for the per-translation-unit constructor
and destructor routines for some C++ translation unit.

Enumerator

NOTE_INSN_MAX

This note is used to get rid of an insn when it isn't safe to patch
the insn out of the chain.

Generated in place of user-declared labels when they are deleted.

Similarly, but for labels that have been present in debug stmts
earlier and thus will only appear with -g.  These must use different
label namespace.

These are used to mark the beginning and end of a lexical block.
See NOTE_BLOCK and reorder_blocks.

This note indicates the start of the real body of the function,
i.e. the point just after all of the parms have been moved into
their homes, etc.

This marks the point immediately after the last prologue insn.

This marks the point immediately prior to the first epilogue insn.

These note where exception handling regions begin and end.
Uses NOTE_EH_HANDLER to identify the region in question.

The location of a variable.

The beginning of a statement.

The entry point for an inlined function.  Its NOTE_BLOCK references
the lexical block whose abstract origin is the inlined function.

Record the struct for the following basic block.  Uses
NOTE_BASIC_BLOCK.  FIXME: Redundant with the basic block pointer
now included in every insn.  NOTE: If there's no CFG anymore, in other words,
if BLOCK_FOR_INSN () == NULL, NOTE_BASIC_BLOCK cannot be considered reliable
anymore.

Mark the inflection point in the instruction stream where we switch
between hot and cold text sections.

When emitting dwarf2 frame information, contains a directive that
should be emitted.

When emitting dwarf2 frame information, contains the number of a debug
label that should be emitted.

This note indicates that the function context must be updated if
the Setjmp/Longjmp exception mechanism is used.

◆ label_kind

Labels carry a two-bit field composed of the ->jump and ->call
bits.  This field indicates whether the label is an alternate

◆ reg_note

enum reg_note

Enumerator

REG_NOTE_MAX

REG_DEP_TRUE is used in scheduler dependencies lists to represent a
read-after-write dependency (i.e. a true data dependency).  This is
here, not grouped with REG_DEP_ANTI and REG_DEP_OUTPUT, because some
passes use a literal 0 for it.

The value in REG dies in this insn (i.e., it is not needed past
this insn).  If REG is set in this insn, the REG_DEAD note may,
but need not, be omitted.

The REG is autoincremented or autodecremented in this insn.

Describes the insn as a whole; it says that the insn sets a
register to a constant value or to be equivalent to a memory
address.  If the register is spilled to the stack then the constant
value should be substituted for it.  The contents of the REG_EQUIV
is the constant value or memory address, which may be different
from the source of the SET although it has the same value.  A
REG_EQUIV note may also appear on an insn which copies a register
parameter to a pseudo-register, if there is a memory address which
could be used to hold that pseudo-register throughout the function.

Like REG_EQUIV except that the destination is only momentarily
equal to the specified rtx.  Therefore, it cannot be used for
substitution; but it can be used for cse.

The register is always nonnegative during the containing loop.
This is used in branches so that decrement and branch instructions
terminating on zero can be matched.  There must be an insn pattern
in the md file named `decrement_and_branch_until_zero' or else this
will never be added to any instructions.

Identifies a register set in this insn and never used.

Points to a CODE_LABEL.  Used by JUMP_INSNs to say that the CODE_LABEL
contained in the REG_LABEL_TARGET note is a possible jump target of
this insn.  This note is an INSN_LIST.

Points to a CODE_LABEL.  Used by any insn to say that the CODE_LABEL
contained in the REG_LABEL_OPERAND note is used by the insn, but as an
operand, not as a jump target (though it may indirectly be a jump
target for a later jump insn).  This note is an INSN_LIST.

REG_DEP_OUTPUT and REG_DEP_ANTI are used in scheduler dependencies lists
to represent write-after-write and write-after-read dependencies
respectively.

REG_BR_PROB is attached to JUMP_INSNs.  It has an
integer value (in an INT_LIST).  For jumps, it is the probability
that this is a taken branch. The integer represents a value of
profile_probability type. Use to_reg_br_prob_note and from_reg_br_prob_note
to extract the actual value.

Attached to a move insn which receives the result of a call; indicates that
the call is malloc-like and that the pointer returned cannot alias anything
else.

REG_BR_PRED is attached to JUMP_INSNs.  It contains
CONCAT of two integer value.  First specifies the branch predictor
that added the note, second specifies the predicted hitrate of
branch in a fixed point arithmetic based on REG_BR_PROB_BASE.

Attached to insns that are RTX_FRAME_RELATED_P, but are too complex
for DWARF to interpret what they imply.  The attached rtx is used
instead of intuition.

Attached to insns that are RTX_FRAME_RELATED_P, but are too complex
for FRAME_RELATED_EXPR intuition.  The insn's first pattern must be
a SET, and the destination must be the CFA register.  The attached
rtx is an expression that defines the CFA.  In the simplest case, the
rtx could be just the stack_pointer_rtx; more common would be a PLUS
with a base register and a constant offset.  In the most complicated
cases, this will result in a DW_CFA_def_cfa_expression with the rtx
expression rendered in a dwarf location expression.

Attached to insns that are RTX_FRAME_RELATED_P, but are too complex
for FRAME_RELATED_EXPR intuition.  This note adjusts the expression
from which the CFA is computed.  The attached rtx defines a new CFA
expression, relative to the old CFA expression.  This rtx must be of
the form (SET new-cfa-reg (PLUS old-cfa-reg const_int)).  If the note
rtx is NULL, we use the first SET of the insn.

Similar to FRAME_RELATED_EXPR, with the additional information that
this is a save to memory, i.e. will result in DW_CFA_offset or the
like.  The pattern or the insn should be a simple store relative to
the CFA.

Similar to FRAME_RELATED_EXPR, with the additional information that this
is a save to a register, i.e. will result in DW_CFA_register.  The insn
or the pattern should be simple reg-reg move.

Attached to insns that are RTX_FRAME_RELATED_P, but are too complex
for FRAME_RELATED_EXPR intuition.  This is a save to memory, i.e. will
result in a DW_CFA_expression.  The pattern or the insn should be a
store of a register to an arbitrary (non-validated) memory address.

Attached to insns that are RTX_FRAME_RELATED_P, but are too complex
for FRAME_RELATED_EXPR intuition.  The DWARF expression computes the value of
the given register.

Attached to insns that are RTX_FRAME_RELATED_P, with the information
that this is a restore operation, i.e. will result in DW_CFA_restore
or the like.  Either the attached rtx, or the destination of the insn's
first pattern is the register to be restored.

Like CFA_RESTORE but without actually emitting CFI.  This can be
used to tell the verification infrastructure that a register is
saved without intending to restore it.

Attached to insns that are RTX_FRAME_RELATED_P, marks insn that sets
vDRAP from DRAP.  If vDRAP is a register, vdrap_reg is initalized
to the argument, if it is a MEM, it is ignored.

Attached to insns that are RTX_FRAME_RELATED_P, indicating a window
save operation, i.e. will result in a DW_CFA_GNU_window_save.
The argument is ignored.

Attached to insns that are RTX_FRAME_RELATED_P, marks the insn as
requiring that all queued information should be flushed *before* insn,
regardless of what is visible in the rtl.  The argument is ignored.
This is normally used for a call instruction which is not exposed to
the rest of the compiler as a CALL_INSN.

Attached to insns that are RTX_FRAME_RELATED_P, indicating an authentication
of the return address. Currently it's only used by AArch64.
The argument is ignored.

Indicates what exception region an INSN belongs in.  This is used
to indicate what region to which a call may throw.  REGION 0
indicates that a call cannot throw at all.  REGION -1 indicates
that it cannot throw, nor will it execute a non-local goto.

Used by haifa-sched to save NOTE_INSN notes across scheduling.

Indicates that a call does not return.

Indicates that an indirect jump is a non-local goto instead of a
computed goto.

This kind of note is generated at each to `setjmp', and similar
functions that can return twice.

This kind of note is generated at each transactional memory
builtin, to indicate we need to generate transaction restart
edges for this insn.

Indicates the cumulative offset of the stack pointer accounting
for pushed arguments.  This will only be generated when
ACCUMULATE_OUTGOING_ARGS is false.

Used for communication between IRA and caller-save.cc, indicates
that the return value of a call can be used to reinitialize a
pseudo reg.

Indicates the instruction is a stack check probe that should not
be combined with other stack adjustments.

Used to mark a call with the function decl called by the call.
The decl might not be available in the call due to splitting of the call
insn.  This note is a SYMBOL_REF.

Indicates that the call is an untyped_call.  These calls are special
in that they set all of the target ABI's return value registers to a
defined value without explicitly saying so.  For example, a typical
untyped_call sequence has the form:

    (call (mem (symbol_ref "foo")))
    (set (reg pseudo1) (reg result1))
    ...
    (set (reg pseudon) (reg resultn))

The ABI specifies that result1..resultn are clobbered by the call,
but the RTL does not indicate that result1..resultn are the results
of the call.

Indicate that a call should not be verified for control-flow consistency.
The target address of the call is assumed as a valid address and no check
to validate a branch to the target address is needed.  The call is marked
when a called function has a 'notrack' attribute.  This note is used by the
compiler when the option -fcf-protection=branch is specified.

The values passed to callee, for debuginfo purposes.

      everything else

All of the expressions that appear only in machine descriptions,
not in RTL used by the compiler itself, are at the end of the file.

Unknown, or no such operation; the enumeration constant should have
value zero.

Used in the cselib routines to describe a value.  Objects of this
kind are only allocated in cselib.cc, in an alloc pool instead of in
GC memory.  The only operand of a VALUE is a cselib_val.
var-tracking requires this to have a distinct integral value from
DECL codes in trees.

The RTL generated for a DEBUG_EXPR_DECL.  It links back to the
DEBUG_EXPR_DECL in the first operand.

---------------------------------------------------------------------
Expressions used in constructing lists.
---------------------------------------------------------------------

A linked list of expressions.

A linked list of instructions.
The insns are represented in print by their uids.

A linked list of integers.

SEQUENCE is used in late passes of the compiler to group insns for
one reason or another.

For example, after delay slot filling, branch instructions with filled
delay slots are represented as a SEQUENCE of length 1 + n_delay_slots,
with the branch instruction in XEXPVEC(seq, 0, 0) and the instructions
occupying the delay slots in the remaining XEXPVEC slots.

Another place where a SEQUENCE may appear, is in REG_FRAME_RELATED_EXPR
notes, to express complex operations that are not obvious from the insn
to which the REG_FRAME_RELATED_EXPR note is attached.  In this usage of
SEQUENCE, the sequence vector slots do not hold real instructions but
only pseudo-instructions that can be translated to DWARF CFA expressions.

Some back ends also use SEQUENCE to group insns in bundles.

Much of the compiler infrastructure is not prepared to handle SEQUENCE
objects.  Only passes after pass_free_cfg are expected to handle them.

Represents a non-global base address.  This is only used in alias.cc.

----------------------------------------------------------------------
Expression types used for things in the instruction chain.

All formats must start with "uu" to handle the chain.
Each insn expression holds an rtl instruction and its semantics
during back-end processing.
See macros in "rtl.h" for the meaning of each rtx->u.fld[].

----------------------------------------------------------------------

An annotation for variable assignment tracking.

An instruction that cannot jump.

An instruction that can possibly jump.
Fields ( rtx->u.fld[] ) have exact same meaning as INSN's.

An instruction that can possibly call a subroutine
but which will not change which instruction comes next
in the current function.
Field ( rtx->u.fld[8] ) is CALL_INSN_FUNCTION_USAGE.
All other fields ( rtx->u.fld[] ) have exact same meaning as INSN's.

Placeholder for tablejump JUMP_INSNs.  The pattern of this kind
of rtx is always either an ADDR_VEC or an ADDR_DIFF_VEC.  These
placeholders do not appear as real instructions inside a basic
block, but are considered active_insn_p instructions for historical
reasons, when jump table data was represented with JUMP_INSNs.

A marker that indicates that control will not flow through.

Holds a label that is followed by instructions.
Operand:
3: is used in jump.cc for the use-count of the label.
4: is used in the sh backend.
5: is a number that is unique in the entire compilation.
6: is the user-given name of the label, if any.

Say where in the code a source line starts, for symbol table's sake.
Operand:
3: note-specific data
4: enum insn_note
5: unique number if insn_note == note_insn_deleted_label.

----------------------------------------------------------------------
Top level constituents of INSN, JUMP_INSN and CALL_INSN.
----------------------------------------------------------------------

Conditionally execute code.
Operand 0 is the condition that if true, the code is executed.
Operand 1 is the code to be executed (typically a SET).

Semantics are that there are no side effects if the condition
is false.  This pattern is created automatically by the if_convert
pass run after reload or by target-specific splitters.

Several operations to be done in parallel (perhaps under COND_EXEC).

A string that is passed through to the assembler as input.
 One can obviously pass comments through by using the
 assembler comment syntax.
 These occur in an insn all by themselves as the PATTERN.
 They also appear inside an ASM_OPERANDS
 as a convenient way to hold a string.

An assembler instruction with operands.
1st operand is the instruction template.
2nd operand is the constraint for the output.
3rd operand is the number of the output this expression refers to.
  When an insn stores more than one value, a separate ASM_OPERANDS
  is made for each output; this integer distinguishes them.
4th is a vector of values of input operands.
5th is a vector of modes and constraints for the input operands.
  Each element is an ASM_INPUT containing a constraint string
  and whose mode indicates the mode of the input operand.
6th is a vector of labels that may be branched to by the asm.
7th is the source line number.

A machine-specific operation.
1st operand is a vector of operands being used by the operation so that
  any needed reloads can be done.
2nd operand is a unique value saying which of a number of machine-specific
  operations is to be performed.
(Note that the vector must be the first operand because of the way that
genrecog.cc record positions within an insn.)

UNSPEC can occur all by itself in a PATTERN, as a component of a PARALLEL,
or inside an expression.
UNSPEC by itself or as a component of a PARALLEL
is currently considered not deletable.

FIXME: Replace all uses of UNSPEC that appears by itself or as a component
of a PARALLEL with USE.

Similar, but a volatile operation and one which may trap.

----------------------------------------------------------------------
Table jump addresses.
----------------------------------------------------------------------

Vector of addresses, stored as full words.
Each element is a LABEL_REF to a CODE_LABEL whose address we want.

Vector of address differences X0 - BASE, X1 - BASE, ...
 First operand is BASE; the vector contains the X's.
 The machine mode of this rtx says how much space to leave
 for each difference and is adjusted by branch shortening if
 CASE_VECTOR_SHORTEN_MODE is defined.
 The third and fourth operands store the target labels with the
 minimum and maximum addresses respectively.
 The fifth operand stores flags for use by branch shortening.
Set at the start of shorten_branches:
 min_align: the minimum alignment for any of the target labels.
 base_after_vec: true iff BASE is after the ADDR_DIFF_VEC.
 min_after_vec: true iff minimum addr target label is after the ADDR_DIFF_VEC.
 max_after_vec: true iff maximum addr target label is after the ADDR_DIFF_VEC.
 min_after_base: true iff minimum address target label is after BASE.
 max_after_base: true iff maximum address target label is after BASE.
Set by the actual branch shortening process:
 offset_unsigned: true iff offsets have to be treated as unsigned.
 scale: scaling that is necessary to make offsets fit into the mode.

 The third, fourth and fifth operands are only valid when
 CASE_VECTOR_SHORTEN_MODE is defined, and only in an optimizing
 compilation.

Memory prefetch, with attributes supported on some targets.
Operand 1 is the address of the memory to fetch.
Operand 2 is 1 for a write access, 0 otherwise.
Operand 3 is the level of temporal locality; 0 means there is no
temporal locality and 1, 2, and 3 are for increasing levels of temporal
locality.

The attributes specified by operands 2 and 3 are ignored for targets
whose prefetch instructions do not support them.

----------------------------------------------------------------------
At the top level of an instruction (perhaps under PARALLEL).
----------------------------------------------------------------------

Assignment.
Operand 1 is the location (REG, MEM, PC or whatever) assigned to.
Operand 2 is the value stored there.
ALL assignment must use SET.
Instructions that do multiple assignments must use multiple SET,
under PARALLEL.

Indicate something is used in a way that we don't want to explain.
For example, subroutine calls will use the register
in which the static chain is passed.

USE cannot appear as an operand of other rtx except for PARALLEL.
USE is not deletable, as it indicates that the operand
is used in some unknown way.

Indicate something is clobbered in a way that we don't want to explain.
For example, subroutine calls will clobber some physical registers
(the ones that are by convention not saved).

CLOBBER cannot appear as an operand of other rtx except for PARALLEL.
CLOBBER of a hard register appearing by itself (not within PARALLEL)
is considered undeletable before reload.

Call a subroutine.
Operand 1 is the address to call.
Operand 2 is the number of arguments.

Return from a subroutine.

Like RETURN, but truly represents only a function return, while
RETURN may represent an insn that also performs other functions
of the function epilogue.  Like RETURN, this may also occur in
conditional jumps.

Special for EH return from subroutine.

Conditional trap.
Operand 1 is the condition.
Operand 2 is the trap code.
For an unconditional trap, make the condition (const_int 1).

----------------------------------------------------------------------
Primitive values for use in expressions.
----------------------------------------------------------------------

numeric integer constant

numeric integer constant

An rtx representation of a poly_wide_int.

fixed-point constant

numeric floating point or integer constant.  If the mode is
VOIDmode it is an int otherwise it has a floating point mode and a
floating point value.  Operands hold the value.  They are all 'w'
and there may be from 2 to 6; see real.h.

Describes a vector constant.

String constant.  Used for attributes in machine descriptions and
for special cases in DWARF2 debug output.  NOT used for source-
language string constants.

This is used to encapsulate an expression whose value is constant
(such as the sum of a SYMBOL_REF and a CONST_INT) so that it will be
recognized as a constant operand rather than by arithmetic instructions.

program counter.  Ordinary jumps are represented
by a SET whose first operand is (PC).

A register.  The "operand" is the register number, accessed with
the REGNO macro.  If this number is less than FIRST_PSEUDO_REGISTER
then a hardware register is being referred to.  The second operand
points to a reg_attrs structure.
This rtx needs to have as many (or more) fields as a MEM, since we
can change REG rtx's into MEMs during reload.

A scratch register.  This represents a register used only within a
single insn.  It will be replaced by a REG during register allocation
or reload unless the constraint indicates that the register won't be
needed, in which case it can remain a SCRATCH.

A reference to a part of another value.  The first operand is the
complete value and the second is the byte offset of the selected part.

This one-argument rtx is used for move instructions
that are guaranteed to alter only the low part of a destination.
Thus, (SET (SUBREG:HI (REG...)) (MEM:HI ...))
has an unspecified effect on the high part of REG,
but (SET (STRICT_LOW_PART (SUBREG:HI (REG...))) (MEM:HI ...))
is guaranteed to alter only the bits of REG that are in HImode.

The actual instruction used is probably the same in both cases,
but the register constraints may be tighter when STRICT_LOW_PART
is in use.

(CONCAT a b) represents the virtual concatenation of a and b
to make a value that has as many bits as a and b put together.
This is used for complex values.  Normally it appears only
in DECL_RTLs and during RTL generation, but not in the insn chain.

(CONCATN [a1 a2 ... an]) represents the virtual concatenation of
all An to make a value.  This is an extension of CONCAT to larger
number of components.  Like CONCAT, it should not appear in the
insn chain.  Every element of the CONCATN is the same size.

A memory location; operand is the address.  The second operand is the
alias set to which this MEM belongs.  We use `0' instead of `w' for this
field so that the field need not be specified in machine descriptions.

Reference to an assembler label in the code for this function.
The operand is a CODE_LABEL found in the insn chain.

Reference to a named label:
Operand 0: label name
Operand 1: tree from which this symbol is derived, or null.
This is either a DECL node, or some kind of constant.

----------------------------------------------------------------------
Expressions for operators in an rtl pattern
----------------------------------------------------------------------

if_then_else.  This is used in representing ordinary
conditional jump instructions.
  Operand:
  0:  condition
  1:  then expr
  2:  else expr

Comparison, produces a condition code result.

plus

Operand 0 minus operand 1.

Minus operand 0.

Multiplication with signed saturation

Multiplication with unsigned saturation

Signed high-part multiplication.

Unsigned high-part multiplication.

Operand 0 divided by operand 1.

Division with signed saturation

Division with unsigned saturation

Remainder of operand 0 divided by operand 1.

Unsigned divide and remainder.

Bitwise operations.

Operand:
 0:  value to be shifted.
 1:  number of bits.

Minimum and maximum values of two operands.  We need both signed and
unsigned forms.  (We cannot use MIN for SMIN because it conflicts
with a macro of the same name.)   The signed variants should be used
with floating point.  Further, if both operands are zeros, or if either
operand is NaN, then it is unspecified which of the two operands is
returned as the result.

These unary operations are used to represent incrementation
and decrementation as they occur in memory addresses.
The amount of increment or decrement are not represented
because they can be understood from the machine-mode of the
containing MEM.  These operations exist in only two cases:
1. pushes onto the stack.
2. created automatically by the auto-inc-dec pass.

These binary operations are used to represent generic address
side-effects in memory addresses, except for simple incrementation
or decrementation which use the above operations.  They are
created automatically by the life_analysis pass in flow.c.
The first operand is a REG which is used as the address.
The second operand is an expression that is assigned to the
register, either before (PRE_MODIFY) or after (POST_MODIFY)
evaluating the address.
Currently, the compiler can only handle second operands of the
form (plus (reg) (reg)) and (plus (reg) (const_int)), where
the first operand of the PLUS has to be the same register as
the first operand of the *_MODIFY.

Comparison operations.  The first 6 are allowed only for integral,
floating-point and vector modes.  LTGT is only allowed for floating-point
modes.  The last 4 are allowed only for integral and vector modes.
For floating-point operations, if either operand is a NaN, then NE returns
true and the remaining operations return false.  The operations other than
EQ and NE may generate an exception on quiet NaNs.

Additional floating-point unordered comparison flavors.

These are equivalent to unordered or ...

Represents the result of sign-extending the sole operand.
The machine modes of the operand and of the SIGN_EXTEND expression
determine how much sign-extension is going on.

Similar for zero-extension (such as unsigned short to int).

Similar but here the operand has a wider mode.

Similar for extending floating-point values (such as SFmode to DFmode).

Conversion of fixed point operand to floating point value.

With fixed-point machine mode:
Conversion of floating point operand to fixed point value.
Value is defined only when the operand's value is an integer.
With floating-point machine mode (and operand with same mode):
Operand is rounded toward zero to produce an integer value
represented in floating point.

Conversion of unsigned fixed point operand to floating point value.

With fixed-point machine mode:
Conversion of floating point operand to *unsigned* fixed point value.
Value is defined only when the operand's value is an integer.

Conversions involving fractional fixed-point types without saturation,
including:
  fractional to fractional (of different precision),
  signed integer to fractional,
  fractional to signed integer,
  floating point to fractional,
  fractional to floating point.
NOTE: fractional can be either signed or unsigned for conversions.

Conversions involving fractional fixed-point types and unsigned integer
without saturation, including:
  unsigned integer to fractional,
  fractional to unsigned integer.
NOTE: fractional can be either signed or unsigned for conversions.

Conversions involving fractional fixed-point types with saturation,
including:
  fractional to fractional (of different precision),
  signed integer to fractional,
  floating point to fractional.
NOTE: fractional can be either signed or unsigned for conversions.

Conversions involving fractional fixed-point types and unsigned integer
with saturation, including:
  unsigned integer to fractional.
NOTE: fractional can be either signed or unsigned for conversions.

Absolute value

Square root

Swap bytes.

Find first bit that is set.
Value is 1 + number of trailing zeros in the arg.,
or 0 if arg is 0.

Count number of leading redundant sign bits (number of leading
sign bits minus one).

Count leading zeros.

Count trailing zeros.

Population count (number of 1 bits).

Population parity (number of 1 bits modulo 2).

Reverse bits.

Reference to a signed bit-field of specified size and position.
Operand 0 is the memory unit (usually SImode or QImode) which
contains the field's first bit.  Operand 1 is the width, in bits.
Operand 2 is the number of bits in the memory unit before the
first bit of this field.
If BITS_BIG_ENDIAN is defined, the first bit is the msb and
operand 2 counts from the msb of the memory unit.
Otherwise, the first bit is the lsb and operand 2 counts from
the lsb of the memory unit.
This kind of expression cannot appear as an lvalue in RTL.

Similar for unsigned bit-field.
But note!  This kind of expression _can_ appear as an lvalue.

For RISC machines.  These save memory when splitting insns.

HIGH are the high-order bits of a constant expression.

LO_SUM is the sum of a register and the low-order bits
of a constant expression.

Describes a merge operation between two vector values.
Operands 0 and 1 are the vectors to be merged, operand 2 is a bitmask
that specifies where the parts of the result are taken from.  Set bits
indicate operand 0, clear bits indicate operand 1.  The parts are defined
by the mode of the vectors.

Describes an operation that selects parts of a vector.
Operands 0 is the source vector, operand 1 is a PARALLEL that contains
a CONST_INT for each of the subparts of the result vector, giving the
number of the source subpart that should be stored into it.

Describes a vector concat operation.  Operands 0 and 1 are the source
vectors, the result is a vector that is as long as operands 0 and 1
combined and is the concatenation of the two source vectors.

Describes an operation that converts a small vector into a larger one by
duplicating the input values.  The output vector mode must have the same
submodes as the input vector mode, and the number of output parts must be
an integer multiple of the number of input parts.

Creation of a vector in which element I has the value BASE + I * STEP,
where BASE is the first operand and STEP is the second.  The result
must have a vector integer mode.

Floating point copysign.  Operand 0 with the sign of operand 1.

Information about the variable and its location.

Used in VAR_LOCATION for a pointer to a decl that is no longer
addressable.

Represents value that argument had on function entry.  The
single argument is the DECL_INCOMING_RTL of the corresponding
parameter.

Used in VAR_LOCATION for a reference to a parameter that has
been optimized away completely.

Used in marker DEBUG_INSNs to avoid being recognized as an insn.

All expressions from this point forward appear only in machine
descriptions.

extern

Return true when insn is a conditional jump.  This function works for
instructions containing PC sets in PARALLELs, UNSPECs or UNSPEC_VOLATILEs.
The instruction may have various other effects so before removing the jump
you must verify onlyjump_p.

Note that unlike condjump_p it returns false for unconditional jumps.

		int	valid_at_insn_p )

extern

Given an insn and condition, return a canonical description of
the test being made.

Given an insn INSN and condition COND, return the condition in a
canonical form to simplify testing by callers.  Specifically:

(1) The code will always be a comparison operation (EQ, NE, GT, etc.).
(2) Both operands will be machine operands.
(3) If an operand is a constant, it will be the second operand.
(4) (LE x const) will be replaced with (LT x <const+1>) and similarly
    for GE, GEU, and LEU.

If the condition cannot be understood, or is an inequality floating-point
comparison which needs to be reversed, 0 will be returned.

If REVERSE is nonzero, then reverse the condition prior to canonizing it.

If EARLIEST is nonzero, it is a pointer to a place where the earliest
insn used in locating the condition was found.  If a replacement test
of the condition is desired, it should be placed in front of that
insn and we will be sure that the inputs are still valid.

If WANT_REG is nonzero, we wish the condition to be relative to that
register, if possible.  Therefore, do not canonicalize the condition
further.  If ALLOW_CC_MODE is nonzero, allow the condition returned
to be a compare to a CC mode register.

If VALID_AT_INSN_P, the condition must be valid at both *EARLIEST
and at INSN.

ZERO_EXTRACT, so no trace of the old contents remains.
Likewise, REG_INC does not count.

REG may be a hard or pseudo reg.  Renumbering is not taken into account,
but for this use that makes no difference, since regs don't overlap
during their lifetimes.  Therefore, this function may be used
at any time after deaths have been computed.

function will only return true if each of those registers will be replaced
by INSN.

FN_TYPE should be LCT_NORMAL for `normal' calls, LCT_CONST for
`const' calls, LCT_PURE for `pure' calls, or another LCT_ value for
other types of library calls.

After emitting to a sequence, restore previous saved state.

If the compiler might have deferred popping arguments while
generating this sequence, and this sequence will not be immediately
inserted into the instruction stream, use do_pending_stack_adjust
before calling get_insns.  That will ensure that the deferred
pops are inserted into this sequence, and not into some random
location in the instruction stream.  See INHIBIT_DEFER_POP for more
information about deferred popping of arguments.

Return the number of "extended" bits there are in X, when interpreted
as a quantity in MODE whose signedness is indicated by UNSIGNEDP.  For
unsigned quantities, this is the number of high-order zero bits.
For signed quantities, this is the number of copies of the sign bit
minus 1.  In both case, this function returns the number of "spare"
bits.  For example, if two quantities for which this function returns
at least 1 are added, the addition is known not to overflow.

This function will always return 0 unless called during combine, which
implies that it must be called from a define_split.

◆ find_args_size_adjust()

poly_int64 find_args_size_adjust ( rtx_insn * insn )

extern

A utility routine used here, in reload, and in try_split.  The insns
after PREV up to and including LAST are known to adjust the stack,
with a final value of END_ARGS_SIZE.  Iterate backward from LAST
placing notes as appropriate.  PREV may be NULL, indicating the
entire insn sequence prior to LAST should be scanned.

The set of allowed stack pointer modifications is small:
  (1) One or more auto-inc style memory references (aka pushes),
  (2) One or more addition/subtraction with the SP as destination,
  (3) A single move insn with the SP as destination,
  (4) A call_pop insn,
  (5) Noreturn call insns if !ACCUMULATE_OUTGOING_ARGS.

Insns in the sequence that do not modify the SP are ignored,
except for noreturn calls.

The return value is the amount of adjustment that can be trivially
verified, via immediate operand or auto-inc.  If the adjustment
cannot be trivially extracted, the return value is HOST_WIDE_INT_MIN.

◆ fis_get_condition()

rtx fis_get_condition ( rtx_insn * jump )

extern

In cprop.cc

Similar to get_condition, only the resulting condition must be
valid at JUMP, instead of at EARLIEST.

This differs from noce_get_condition in ifcvt.cc in that we prefer not to
settle for the condition variable in the jump instruction being integral.
We prefer to be able to record the value of a user variable, rather than
the value of a temporary used in a condition.  This could be solved by
recording the value of *every* register scanned by canonicalize_condition,
but this would require some code reorganization.

be returned.

of the condition is desired, it should be placed in front of that
insn and we will be sure that the inputs are still valid.  If EARLIEST

compare CC mode register.

◆ get_stack_check_protect()

HOST_WIDE_INT get_stack_check_protect ( void )

extern

Return the number of bytes to "protect" on the stack for -fstack-check.

"protect" in the context of -fstack-check means how many bytes we need
to always ensure are available on the stack; as a consequence, this is
also how many bytes are first skipped when probing the stack.

On some targets we want to reuse the -fstack-check prologue support
to give a degree of protection against stack clashing style attacks.

In that scenario we do not want to skip bytes before probing as that
would render the stack clash protections useless.

So we never use STACK_CHECK_PROTECT directly.  Instead we indirectly
use it through this helper, which allows to provide different values
for -fstack-check and -fstack-clash-protection.

Hash an rtx.  We are careful to make sure the value is never negative.
Equivalent registers hash identically.
MODE is used in hashing for CONST_INTs only;
otherwise the mode of X is used.

Store 1 in DO_NOT_RECORD_P if any subexpression is volatile.

If HASH_ARG_IN_MEMORY_P is not NULL, store 1 in it if X contains
a MEM rtx which does not have the MEM_READONLY_P flag set.

Note that cse_insn knows that the hash code of a MEM expression
is just (int) MEM plus the hash code of the address.

Call CB on each rtx if CB is not NULL.
When the callback returns true, we continue with the new rtx.

CODE_LABEL referenced in INSN as a jump target, then store the last
one in JUMP_LABEL (INSN).  For a tablejump, this must be the label
for the ADDR_VEC.  Store any other jump targets as REG_LABEL_TARGET
notes.  If INSN is an INSN or a CALL_INSN or non-target operands of
a JUMP_INSN, and there is at least one CODE_LABEL referenced in
INSN, add a REG_LABEL_OPERAND note containing that label to INSN.
For returnjumps, the JUMP_LABEL will also be set as appropriate.

Note that two labels separated by a loop-beginning note
must be kept distinct if we have not yet done loop-optimization,
because the gap between them is where loop-optimize
will want to move invariant code to.  CROSS_JUMP tells us
that loop-optimization is done with.

◆ may_trap_or_fault_p()

bool may_trap_or_fault_p ( const_rtx x )

extern

Same as above, but additionally return true if evaluating rtx X might
cause a fault.  We define a fault for the purpose of this function as a
erroneous execution condition that cannot be encountered during the normal
execution of a valid program; the typical example is an unaligned memory
access on a strict alignment machine.  The compiler guarantees that it
doesn't generate code that will fault from a valid program, but this
guarantee doesn't mean anything for individual instructions.  Consider
the following example:

   struct S { int d; union { char *cp; int *ip; }; };

   int foo(struct S *s)
   {
     if (s->d == 1)
       return *s->ip;
     else
       return *s->cp;
   }

on a strict alignment machine.  In a valid program, foo will never be
invoked on a structure for which d is equal to 1 and the underlying
unique field of the union not aligned on a 4-byte boundary, but the
expression *s->ip might cause a fault if considered individually.

At the RTL level, potentially problematic expressions will almost always
verify may_trap_p; for example, the above dereference can be emitted as
(mem:SI (reg:P)) and this expression is may_trap_p for a generic register.
However, suppose that foo is inlined in a caller that causes s->cp to
point to a local character variable and guarantees that s->d is not set
to 1; foo may have been effectively translated into pseudo-RTL as:

   if ((reg:SI) == 1)
     (set (reg:SI) (mem:SI (%fp - 7)))
   else
     (set (reg:QI) (mem:QI (%fp - 7)))

Now (mem:SI (%fp - 7)) is considered as not may_trap_p since it is a
memory reference to a stack slot, but it will certainly cause a fault
on a strict alignment machine.

Call FUN on each register or MEM that is stored into or clobbered by X.
 (X would be the pattern of an insn).  DATA is an arbitrary pointer,
 ignored by note_stores, but passed to FUN.

 FUN receives three arguments:
 1. the REG, MEM or PC being stored in or clobbered,
 2. the SET or CLOBBER rtx that does the store,
 3. the pointer DATA provided to note_stores.

If the item being stored in or clobbered is a SUBREG of a hard register,
the SUBREG will be passed.

extern

Like notes_stores, but call FUN for each expression that is being
referenced in PBODY, a pointer to the PATTERN of an insn.  We only call
FUN for each expression, not any interior subexpressions.  FUN receives a
pointer to the expression and the DATA passed to this function.

Note that this is not quite the same test as that done in reg_referenced_p
since that considers something as being referenced if it is being
partially set, while we do not.

◆ operand_subword()

rtx operand_subword	(	rtx	op,
		poly_uint64	offset,
		int	validate_address,
		machine_mode	mode )

extern

Return subword OFFSET of operand OP.
 The word number, OFFSET, is interpreted as the word number starting
 at the low-order address.  OFFSET 0 is the low-order word if not
 WORDS_BIG_ENDIAN, otherwise it is the high-order word.

 If we cannot extract the required word, we return zero.  Otherwise,
 an rtx corresponding to the requested word will be returned.

 VALIDATE_ADDRESS is nonzero if the address should be validated.  Before
 reload has completed, a valid address will always be returned.  After
 reload, if a valid address cannot be returned, we return zero.

 If VALIDATE_ADDRESS is zero, we simply form the required address; validating
 it is the responsibility of the caller.

 MODE is the mode of OP in case it is a CONST_INT.

 ??? This is still rather broken for some cases.  The problem for the
 moment is that all callers of this thing provide no 'goal mode' to
 tell us to work with.  This exists because all callers were written
 in a word based SUBREG world.
 Now use of this function can be deprecated by simplify_subreg in most
 cases.

Similar to `operand_subword', but never return 0.  If we can't
extract the required subword, put OP into a register and try again.
The second attempt must succeed.  We always validate the address in
this case.

return an rtx to refer to it.
Otherwise, output such a constant in memory
and generate an rtx for it.

If DEFER is nonzero, this constant can be deferred and output only
if referenced in the function after all optimizations.

◆ read_dependence()

bool read_dependence	(	const_rtx	mem,
		const_rtx	x )

extern

Functions to compute memory dependencies.

Since we process the insns in execution order, we can build tables
to keep track of what registers are fixed (and not aliased), what registers
are varying in known ways, and what registers are varying in unknown
ways.

If both memory references are volatile, then there must always be a
dependence between the two references, since their order cannot be
changed.  A volatile and non-volatile reference can be interchanged
though.

We also must allow AND addresses, because they may generate accesses
outside the object being referenced.  This is used to generate aligned
addresses from unaligned addresses, for instance, the alpha
storeqi_unaligned pattern.

Read dependence: X is read after read in MEM takes place.  There can
only be a dependence here if both reads are volatile, or if either is
an explicit barrier.

References ALIAS_SET_MEMORY_BARRIER, MEM_ALIAS_SET, and MEM_VOLATILE_P.

◆ read_modify_subreg_p()

Return true if X is a SUBREG and if storing a value to X would

target, using a SUBREG to store to one half of a DImode REG would
preserve the other half.

it may be deleted.

Normally, NLABEL will be a label, but it may also be a RETURN rtx;

return insn.

◆ remove_insn()

void remove_insn ( rtx_insn * insn )

extern

Unlink INSN from the insn chain.

This function knows how to handle sequences.

This function does not invalidate data flow information associated with
INSN (i.e. does not call df_insn_delete).  That makes this function
usable for only disconnecting an insn from the chain, and re-emit it
elsewhere later.

To later insert INSN elsewhere in the insn chain via add_insn and
similar functions, PREV_INSN and NEXT_INSN must be nullified by
the caller.  Nullifying them here breaks many insn chain walks.

To really delete an insn and related DF information, use delete_insn.

Check whether instruction pattern PAT contains a SET with the following
properties:

- the SET is executed unconditionally; and
- either:
  - the destination of the SET is a REG that contains REGNO; or
  - both:
    - the destination of the SET is a SUBREG of such a REG; and
    - writing to the subreg clobbers all of the SUBREG_REG
      (in other words, read_modify_subreg_p is false).

If PAT does have a SET like that, return the set, otherwise return null.

This is intended to be an alternative to single_set for passes that
can handle patterns with multiple_sets.

Simplify X, an rtx expression.

Return the simplified expression or NULL if no simplifications
were possible.

This is the preferred entry point into the simplification routines;
however, we still allow passes to call the more specific routines.

Right now GCC has three (yes, three) major bodies of RTL simplification
code that need to be unified.

     1. fold_rtx in cse.cc.  This code uses various CSE specific
        information to aid in RTL simplification.

     2. simplify_rtx in combine.cc.  Similar to fold_rtx, except that
        it uses combine specific information to aid in RTL
        simplification.

     3. The routines in this file.


Long term we want to only have one body of simplification code; to
get to that state I recommend the following steps:

     1. Pour over fold_rtx & simplify_rtx and move any simplifications
        which are not pass dependent state into these routines.

     2. As code is moved by #1, change fold_rtx & simplify_rtx to
        use this routine whenever possible.

     3. Allow for pass dependent state to be provided to these
        routines and add simplifications based on the pass dependent
        state.  Remove code from cse.cc & combine.cc that becomes
        redundant/dead.

 It will take time, but ultimately the compiler will be easier to
 maintain and improve.  It's totally silly that when we add a
 simplification that it needs to be added to 4 places (3 for RTL
 simplification and 1 for tree simplification.

void subreg_get_info	(	unsigned int	xregno,
		machine_mode	xmode,

extern

Fill in information about a subreg of a hard register.
xregno - A regno of an inner hard subreg_reg (or what will become one).
xmode  - The mode of xregno.
offset - The byte offset.
ymode  - The mode of a top level SUBREG (or what may become one).
info   - Pointer to structure to fill in.

Rather than considering one particular inner register (and thus one
particular "outer" register) in isolation, this function really uses
XREGNO as a model for a sequence of isomorphic hard registers.  Thus the
function does not check whether adding INFO->offset to XREGNO gives
a valid hard register; even if INFO->offset + XREGNO is out of range,
there might be another register of the same type that is in range.
Likewise it doesn't check whether targetm.hard_regno_mode_ok accepts
the new register, since that can depend on things like whether the final
register number is even or odd.  Callers that want to check whether
this particular subreg can be replaced by a simple (reg ...) should
use simplify_subreg_regno.

Middle-to-low level generation of rtx code and insns.

This file contains support functions for creating rtl expressions
and manipulating them in the doubly-linked chain of insns.

The patterns of the insns are created by machine-dependent
routines in insn-emit.cc, which is generated automatically from
the machine description.  These routines make the individual rtx's
of the pattern with `gen_rtx_fmt_ee' and others in genrtl.[ch],
which are automatically generated from rtl.def; what is machine
dependent is the kind of rtx's they make and what arguments they
use.

◆ rtl_hooks

struct rtl_hooks rtl_hooks

extern

Each pass can provide its own.

◆ rtx_class

enum rtx_class rtx_class[NUM_RTX_CODE]

extern

Indexed by rtx code, gives a character representing the "class" of
that rtx code.  See rtl.def for documentation on the defined classes.

◆ rtx_code_size

const unsigned char rtx_code_size[NUM_RTX_CODE]

extern

Indexed by rtx code, gives the size of the rtx in bytes.

◆ rtx_format

const char* const rtx_format[NUM_RTX_CODE]

extern

Indexed by rtx code, gives a sequence of operand-types for
rtx's of that code.  The sequence is a C string in which
each character describes one operand.

◆ SRP_POINTER

const int SRP_POINTER = -1

Valid for subregs which are SUBREG_PROMOTED_VAR_P().  In that case
this gives the necessary extensions:
0  - signed (SPR_SIGNED)
1  - normal unsigned (SPR_UNSIGNED)
2  - value is both sign and unsign extended for mode
     (SPR_SIGNED_AND_UNSIGNED).
-1 - pointer unsigned, which most often can be handled like unsigned
     extension, except for generating instructions where we need to
     emit special code (ptr_extend insns) on some architectures
     (SPR_POINTER).

◆ SRP_SIGNED

const int SRP_SIGNED = 0

◆ SRP_SIGNED_AND_UNSIGNED

const int SRP_SIGNED_AND_UNSIGNED = 2

◆ SRP_UNSIGNED

const int SRP_UNSIGNED = 1

◆ stack_limit_rtx

rtx stack_limit_rtx

extern

In toplev.cc

-f flags.

When non-NULL, indicates that whenever space is allocated on the
stack, the resulting stack pointer must not pass this
address---that is, for stacks that grow downward, the stack pointer
must always be greater than or equal to this address; for stacks
that grow upward, the stack pointer must be less than this address.
At present, the rtx may be either a REG or a SYMBOL_REF, although
the support provided depends on the backend.
