◆ allocate_struct_function()

void allocate_struct_function	(	tree	fndecl,

extern

Allocate a function structure for FNDECL and set its contents
to the defaults.  Set cfun to the newly-allocated object.
Some of the helper functions invoked during initialization assume
that cfun has already been set.  Therefore, assign the new object
directly into cfun and invoke the back end hook explicitly at the
very end, rather than initializing a temporary and calling set_cfun
on it.

ABSTRACT_P is true if this is a function that will never be seen by
the middle-end.  Such functions are front-end concepts (like C++
function templates) that do not correspond directly to functions
placed in object files.

◆ assign_stack_local_1()

rtx assign_stack_local_1	(	machine_mode	mode,
		poly_int64	size,
		int	align,
		int	kind )

extern

Allocate a stack slot of SIZE bytes and return a MEM rtx for it
with machine mode MODE.

ALIGN controls the amount of alignment for the address of the slot:
0 means according to MODE,
-1 means use BIGGEST_ALIGNMENT and round size to multiple of that,
-2 means use BITS_PER_UNIT,
positive specifies alignment boundary in bits.

KIND has ASLK_REDUCE_ALIGN bit set if it is OK to reduce
alignment and ASLK_RECORD_PAD bit set if we should remember
extra space we allocated for alignment purposes.  When we are
called from assign_stack_temp_for_type, it is not set so we don't
track the same stack slot in two independent lists.

We do not round to stack_boundary here.

extern

Compute the size and offset from the start of the stacked arguments for a
parm passed in mode PASSED_MODE and with type TYPE.

INITIAL_OFFSET_PTR points to the current offset into the stacked
arguments.

The starting offset and size for this parm are returned in
LOCATE->OFFSET and LOCATE->SIZE, respectively.  When IN_REGS is
nonzero, the offset is that of stack slot, which is returned in
LOCATE->SLOT_OFFSET.  LOCATE->ALIGNMENT_PAD is the amount of
padding required from the initial offset ptr to the stack slot.

IN_REGS is nonzero if the argument will be passed in registers.  It will
never be set if REG_PARM_STACK_SPACE is not defined.

REG_PARM_STACK_SPACE is the number of bytes of stack space reserved
for arguments which are passed in registers.

FNDECL is the function in which the argument was defined.

There are two types of rounding that are done.  The first, controlled by
TARGET_FUNCTION_ARG_BOUNDARY, forces the offset from the start of the
argument list to be aligned to the specific boundary (in bits).  This
rounding affects the initial and starting offsets, but not the argument
size.

The second, controlled by TARGET_FUNCTION_ARG_PADDING and PARM_BOUNDARY,
optionally rounds the size of the parm to PARM_BOUNDARY.  The
initial offset is not affected by this rounding, while the size always
is and the starting offset may be.

LOCATE->OFFSET will be negative for ARGS_GROW_DOWNWARD case;
INITIAL_OFFSET_PTR is positive because locate_and_pad_parm's
callers pass in the total size of args so far as
INITIAL_OFFSET_PTR.  LOCATE->SIZE is always positive.

◆ thread_prologue_and_epilogue_insns()

void thread_prologue_and_epilogue_insns ( void )

extern

Generate the prologue and epilogue RTL if the machine supports it.  Thread
this into place with notes indicating where the prologue ends and where
the epilogue begins.  Update the basic block information when possible.

Notes on epilogue placement:
There are several kinds of edges to the exit block:
* a single fallthru edge from LAST_BB
* possibly, edges from blocks containing sibcalls
* possibly, fake edges from infinite loops

The epilogue is always emitted on the fallthru edge from the last basic
block in the function, LAST_BB, into the exit block.

If LAST_BB is empty except for a label, it is the target of every
other basic block in the function that ends in a return.  If a
target has a return or simple_return pattern (possibly with
conditional variants), these basic blocks can be changed so that a
return insn is emitted into them, and their target is adjusted to
the real exit block.

Notes on shrink wrapping: We implement a fairly conservative
version of shrink-wrapping rather than the textbook one.  We only
generate a single prologue and a single epilogue.  This is
sufficient to catch a number of interesting cases involving early
exits.

First, we identify the blocks that require the prologue to occur before
them.  These are the ones that modify a call-saved register, or reference
any of the stack or frame pointer registers.  To simplify things, we then
mark everything reachable from these blocks as also requiring a prologue.
This takes care of loops automatically, and avoids the need to examine
whether MEMs reference the frame, since it is sufficient to check for
occurrences of the stack or frame pointer.

We then compute the set of blocks for which the need for a prologue
is anticipatable (borrowing terminology from the shrink-wrapping
description in Muchnick's book).  These are the blocks which either
require a prologue themselves, or those that have only successors
where the prologue is anticipatable.  The prologue needs to be
inserted on all edges from BB1->BB2 where BB2 is in ANTIC and BB1
is not.  For the moment, we ensure that only one such edge exists.

The epilogue is placed as described above, but we make a
distinction between inserting return and simple_return patterns
when modifying other blocks that end in a return.  Blocks that end
in a sibcall omit the sibcall_epilogue if the block is not in
ANTIC.
