		machine_mode	mode,
		poly_int64	offset,
		int	validate,
		int	adjust_address,
		int	adjust_object,
		poly_int64	size )

extern

Return a memory reference like MEMREF, but with its mode changed
to MODE and its address offset by OFFSET bytes.  If VALIDATE is
nonzero, the memory address is forced to be valid.
If ADJUST_ADDRESS is zero, OFFSET is only used to update MEM_ATTRS
and the caller is responsible for adjusting MEMREF base register.
If ADJUST_OBJECT is zero, the underlying object associated with the
memory reference is left unchanged and the caller is responsible for
dealing with it.  Otherwise, if the new memory reference is outside
the underlying object, even partially, then the object is dropped.
SIZE, if nonzero, is the size of an access in cases where MODE
has no inherent size.

MEMREF offset by OFFSET bytes.  If VALIDATE is
nonzero, the memory address is forced to be valid.

◆ adjust_reg_mode()

void adjust_reg_mode	(	rtx	reg,

extern

Adjust REG in-place so that it has mode MODE.  It is assumed that the
new register is a (possibly paradoxical) lowpart of the old one.

extern

Return a memory reference like MEMREF, but with its mode changed

(VOIDmode means don't change the mode.
NULL for ADDR means don't change the address.)

Like change_address_1 with VALIDATE nonzero, but we are not saying in what
way we are changing MEMREF, so we only preserve the alias set.

pattern.

rtx copy_insn_1 ( rtx orig )

extern

Recursively create a new copy of an rtx for copy_insn.
This function differs from copy_rtx in that it handles SCRATCHes and
ASM_OPERANDs properly.
Normally, this function is not used directly; use copy_insn as front end.
However, you could first copy an insn pattern with copy_insn and then use
this function afterwards to properly copy any REG_NOTEs containing
SCRATCHes.

Given MEM, a result from assign_stack_local, fill in the memory
attributes as appropriate for a register allocator spill slot.
These slots are not aliasable by other memory.  We arrange for
them all to use a single MEM_EXPR, so that the aliasing code can
work properly in the case of shared spill slots.

◆ set_reg_attrs_for_parm()

extern

Set the register attributes for registers contained in PARM_RTX.
Use needed values from memory attributes of MEM.

◆ set_reg_attrs_from_value()

void set_reg_attrs_from_value	(	rtx	reg,

extern

Copy REG's attributes from X, if X has any attributes.  If REG and X
have different modes, REG is a (possibly paradoxical) lowpart of X.

MODE and adjusted by OFFSET.

Return a memory reference like MEMREF, but with its mode widened to
MODE and offset by OFFSET.  This would be used by targets that e.g.
cannot issue QImode memory operations and have to use SImode memory
operations plus masking logic.
