Detailed Description

A base class for vec_rtx_properties; see there for details.

Constructor & Destructor Documentation

◆ vec_rtx_properties_base()

vec_rtx_properties_base::vec_rtx_properties_base ( )

inline

References m_storage, rtx_properties::ref_begin, rtx_properties::ref_end, rtx_properties::ref_iter, and SIZE.

◆ ~vec_rtx_properties_base()

vec_rtx_properties_base::~vec_rtx_properties_base ( )

inline

References free(), m_storage, rtx_properties::ref_begin, and UNLIKELY.

Member Function Documentation

◆ grow()

void vec_rtx_properties_base::grow ( ptrdiff_t start )

protected

Grow the storage by a bit while keeping the contents of the first
START elements.

References m_storage, rtx_properties::ref_begin, rtx_properties::ref_end, and rtx_properties::ref_iter.

◆ has_side_effects()

bool rtx_properties::has_side_effects ( ) const

inlineinherited

Return true if the rtx has side effects, in the sense of
side_effects_p (except for side_effects_p's special handling
of combine.cc clobbers).

References rtx_properties::has_call, rtx_properties::has_pre_post_modify, and rtx_properties::has_volatile_refs.

◆ num_refs()

size_t rtx_properties::num_refs ( ) const

inlineinherited

References rtx_properties::ref_begin, and rtx_properties::ref_iter.

◆ refs()

iterator_range< rtx_obj_reference * > rtx_properties::refs ( ) const

inlineinherited

Return an iterator range for all the references, suitable for
range-based for loops.

References rtx_properties::ref_begin, and rtx_properties::ref_iter.

◆ try_to_add_dest()

void rtx_properties::try_to_add_dest	(	const_rtx	x,
		unsigned int	flags = 0 )

inherited

Add a description of destination X to this object.  FLAGS is a bitmask
of rtx_obj_reference flags that describe the context.

This routine accepts all rtxes that can legitimately appear in a
SET_DEST.

References GET_CODE, GET_MODE, i, rtx_obj_flags::IN_MEM_LOAD, rtx_obj_flags::IN_MEM_STORE, rtx_obj_flags::IN_SUBREG, rtx_obj_flags::IS_READ, rtx_obj_flags::IS_WRITE, LIKELY, MEM_P, MEM_REGNO, read_modify_subreg_p(), rtx_properties::ref_end, rtx_properties::ref_iter, REG_P, REGNO, rtx_obj_flags::STICKY_FLAGS, SUBREG_REG, rtx_properties::try_to_add_dest(), rtx_properties::try_to_add_reg(), rtx_properties::try_to_add_src(), UNLIKELY, XEXP, XVECEXP, and XVECLEN.

Referenced by rtx_properties::try_to_add_dest(), rtx_properties::try_to_add_insn(), rtx_properties::try_to_add_pattern(), and rtx_properties::try_to_add_src().

◆ try_to_add_insn()

void rtx_properties::try_to_add_insn	(	const rtx_insn *	insn,
		bool	include_notes )

inherited

Try to add a description of INSN to this object, stopping once
the REF_END limit has been reached.  INCLUDE_NOTES is true if the
description should include REG_EQUAL and REG_EQUIV notes; all such
references will then be marked with rtx_obj_flags::IN_NOTE.

For calls, this description includes all accesses in
CALL_INSN_FUNCTION_USAGE.  It also include all implicit accesses
to global registers by the target function.  However, it does not
include clobbers performed by the target function; callers that want
this information should instead use the function_abi interface.

◆ try_to_add_note()

void rtx_properties::try_to_add_note ( const_rtx x )

inlineinherited

Like add_src, but treat X has being part of a REG_EQUAL or
REG_EQUIV note.

References rtx_obj_flags::IN_NOTE, and rtx_properties::try_to_add_src().

Referenced by rtx_properties::try_to_add_insn().

◆ try_to_add_pattern()

void rtx_properties::try_to_add_pattern ( const_rtx pat )

inherited

Try to add a description of instruction pattern PAT to this object,
stopping once the REF_END limit has been reached.

◆ try_to_add_reg()

void rtx_properties::try_to_add_reg	(	const_rtx	x,
		unsigned int	flags = 0 )

inherited

Try to add a description of REG X to this object, stopping once
the REF_END limit has been reached.  FLAGS is a bitmask of
rtx_obj_reference flags that describe the context.

References END_REGNO(), GET_MODE, rtx_obj_flags::IS_MULTIREG, rtx_properties::ref_end, rtx_properties::ref_iter, REG_NREGS, and REGNO.

◆ try_to_add_src()

void rtx_properties::try_to_add_src	(	const_rtx	x,
		unsigned int	flags = 0 )

inherited

Try to add a description of source X to this object, stopping once
the REF_END limit has been reached.  FLAGS is a bitmask of
rtx_obj_reference flags that describe the context.

This routine accepts all rtxes that can legitimately appear in a SET_SRC.
