11.8.1 GIMPLE_ASM

GIMPLE function: gasm *gimple_build_asm_vec ( const char *string, vec<tree, va_gc> *inputs, vec<tree, va_gc> *outputs, vec<tree, va_gc> *clobbers, vec<tree, va_gc> *labels)

Build a GIMPLE_ASM statement. This statement is used for building in-line assembly constructs. STRING is the assembly code. INPUTS, OUTPUTS, CLOBBERS and LABELS are the inputs, outputs, clobbered registers and labels.

GIMPLE function: unsigned gimple_asm_ninputs (const gasm *g)

Return the number of input operands for GIMPLE_ASM G.

GIMPLE function: unsigned gimple_asm_noutputs (const gasm *g)

Return the number of output operands for GIMPLE_ASM G.

GIMPLE function: unsigned gimple_asm_nclobbers (const gasm *g)

Return the number of clobber operands for GIMPLE_ASM G.

GIMPLE function: tree gimple_asm_input_op (const gasm *g, unsigned index)

Return input operand INDEX of GIMPLE_ASM G.

GIMPLE function: void gimple_asm_set_input_op (gasm *g, unsigned index, tree in_op)

Set IN_OP to be input operand INDEX in GIMPLE_ASM G.

GIMPLE function: tree gimple_asm_output_op (const gasm *g, unsigned index)

Return output operand INDEX of GIMPLE_ASM G.

GIMPLE function: void gimple_asm_set_output_op (gasm *g, unsigned index, tree out_op)

Set OUT_OP to be output operand INDEX in GIMPLE_ASM G.

GIMPLE function: tree gimple_asm_clobber_op (const gasm *g, unsigned index)

Return clobber operand INDEX of GIMPLE_ASM G.

GIMPLE function: void gimple_asm_set_clobber_op (gasm *g, unsigned index, tree clobber_op)

Set CLOBBER_OP to be clobber operand INDEX in GIMPLE_ASM G.

GIMPLE function: const char * gimple_asm_string (const gasm *g)

Return the string representing the assembly instruction in GIMPLE_ASM G.

GIMPLE function: bool gimple_asm_volatile_p (const gasm *g)

Return true if G is an asm statement marked volatile.

GIMPLE function: void gimple_asm_set_volatile (gasm *g, bool volatile_p)

Mark asm statement G as volatile or non-volatile based on VOLATILE_P.
