Subject: middle-end: Fix signbit tests when ran on ISA with support for masks.
X-Git-Tag: basepoints/gcc-13~3202
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=92617a8e2af06c74e7df514d3560f246daf411e9;p=thirdparty%2Fgcc.git

middle-end: Fix signbit tests when ran on ISA with support for masks.

These test don't work on vector ISAs where the truth
type don't match the vector mode of the operation.

However I still want the tests to run on these
architectures but just turn off the ISA modes that
enable masks.

This thus turns off SVE is it's on and turns off
AVX512 if it's on.

gcc/testsuite/ChangeLog:

	* gcc.dg/signbit-2.c: Turn off masks.
	* gcc.dg/signbit-5.c: Likewise.
