Function Documentation

◆ by_pieces_ninsns()

unsigned HOST_WIDE_INT by_pieces_ninsns ( unsigned HOST_WIDE_INT l,
unsigned int align,
unsigned int max_size,
by_pieces_operation op )
extern
Return number of insns required to perform operation OP by pieces
for L bytes.  ALIGN (in bits) is maximum alignment we can assume.   

References alignment_for_piecewise_move(), COMPARE_BY_PIECES, gcc_assert, GET_MODE_ALIGNMENT, GET_MODE_SIZE(), MOVE_MAX_PIECES, optab_handler(), ROUND_UP, targetm, and widest_fixed_size_mode_for_size().

◆ elf_record_gcc_switches()

void elf_record_gcc_switches ( const char * options)
extern
An example implementation for ELF targets.  Defined in varasm.cc   
This function provides a possible implementation of the
TARGET_ASM_RECORD_GCC_SWITCHES target hook for ELF targets.  When triggered
by -frecord-gcc-switches it creates a new mergeable, string section in the
assembler output file called TARGET_ASM_RECORD_GCC_SWITCHES_SECTION which
contains the switches in ASCII format.

FIXME: This code does not correctly handle double quote characters
that appear inside strings, (it strips them rather than preserving them).
FIXME: ASM_OUTPUT_ASCII, as defined in config/elfos.h will not emit NUL
characters - instead it treats them as sub-string separators.  Since
we want to emit NUL strings terminators into the object file we have to use
ASM_OUTPUT_SKIP.   

References asm_out_file, ASM_OUTPUT_ASCII, get_section(), NULL, SECTION_DEBUG, SECTION_ENTSIZE, SECTION_MERGE, SECTION_STRINGS, switch_to_section(), and targetm.

◆ estimated_poly_value()

HOST_WIDE_INT estimated_poly_value ( poly_int64 x,
poly_value_estimate_kind kind = POLY_VALUE_LIKELY )
inline
Return an estimate of the runtime value of X, for use in things
like cost calculations or profiling frequencies.  Note that this
function should never be used in situations where the actual
runtime value is needed for correctness, since the function only
provides a rough guess.

◆ get_move_ratio()

unsigned int get_move_ratio ( bool speed_p)
extern
For hooks which use the MOVE_RATIO macro, this gives the legacy default
behavior.   
For hooks which use the MOVE_RATIO macro, this gives the legacy default
behavior.  SPEED_P is true if we are compiling for speed.   

Referenced by default_use_by_pieces_infrastructure_p(), and sra_get_max_scalarization_size().

◆ mode_can_transfer_bits()

bool mode_can_transfer_bits ( machine_mode mode)
inline
Return true when MODE can be used to copy GET_MODE_BITSIZE bits
unchanged.

Referenced by types_risk_mangled_binary_repr_p(), and vn_reference_eq().

◆ stmt_in_inner_loop_p()

bool stmt_in_inner_loop_p ( vec_info * vinfo,
class _stmt_vec_info * stmt_info )
extern
Return TRUE iff the given statement is in an inner loop relative to
the loop being vectorized.

◆ stmt_vectype()

tree stmt_vectype ( class _stmt_vec_info * stmt_info)
extern
These are defined in tree-vect-stmts.cc.   
For lang_hooks.types.type_for_mode.   
Return the vectorized type for the given statement.   

References STMT_VINFO_VECTYPE.

Referenced by vect_determine_vf_for_stmt_1(), and vect_get_vec_defs_for_operand().

◆ target_default_pointer_address_modes_p()

bool target_default_pointer_address_modes_p ( void )
extern
Some places still assume that all pointer or address modes are the
standard Pmode and ptr_mode.  These optimizations become invalid if
the target actually supports multiple different modes.  For now,
we disable such optimizations on such targets, using this function.

Referenced by find_base_term(), find_base_value(), nonzero_bits1(), num_sign_bit_copies1(), and simplify_context::simplify_unary_operation_1().

◆ verify_type_context()

bool verify_type_context ( location_t loc,
type_context_kind context,
const_tree type,
bool silent_p )
extern
A wrapper around TARGET_VERIFY_TYPE_CONTEXT that makes the silent_p
parameter default to false and that weeds out error_mark_node.   

References error_mark_node, gcc_assert, targetm, and TYPE_P.

◆ VECT_COMPARE_COSTS

const unsigned int VECT_COMPARE_COSTS = 1U << 0
Flags returned by TARGET_VECTORIZE_AUTOVECTORIZE_VECTOR_MODES:

VECT_COMPARE_COSTS
    Tells the loop vectorizer to try all the provided modes and
    pick the one with the lowest cost.  By default the vectorizer
    will choose the first mode that works.
