Subject: x86-64: Check CMPXCHG16B for x86-64-v[234]
X-Git-Tag: basepoints/gcc-12~4493
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=16664e6e4fb4281be6477c13989740d44c963c77;p=thirdparty%2Fgcc.git

x86-64: Check CMPXCHG16B for x86-64-v[234]

x86-64-v2 includes CMPXCHG16B.  Since -mcx16 enables CMPXCHG16B and
defines __GCC_HAVE_SYNC_COMPARE_AND_SWAP_16, check it in x86-64-v[234]
tests.

	PR target/97250
	* gcc.target/i386/x86-64-v2.c: Verify that
	__GCC_HAVE_SYNC_COMPARE_AND_SWAP_16 is defined.
	* gcc.target/i386/x86-64-v3.c: Likewise.
	* gcc.target/i386/x86-64-v4.c: Likewise.
