Subject: x86: Define __APX_INLINE_ASM_USE_GPR32__
X-Git-Tag: basepoints/gcc-15~287
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=18e94e04dae724c61cbc13ace85fa68f2deda900;p=thirdparty%2Fgcc.git

x86: Define __APX_INLINE_ASM_USE_GPR32__

Define __APX_INLINE_ASM_USE_GPR32__ for -mapx-inline-asm-use-gpr32.
When __APX_INLINE_ASM_USE_GPR32__ is defined, inline asm statements
should contain only instructions compatible with r16-r31.

gcc/

	PR target/114587
	* config/i386/i386-c.cc (ix86_target_macros_internal): Define
	__APX_INLINE_ASM_USE_GPR32__ for -mapx-inline-asm-use-gpr32.

gcc/testsuite/

	PR target/114587
	* gcc.target/i386/apx-3.c: Likewise.
