Subject: testsuite: adjust tests for FIRSTP/LASTP SVE2 instructions
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=06a379c9775fa10c74b76a47f6433ee2e052bcf0;p=thirdparty%2Fgcc.git

testsuite: adjust tests for FIRSTP/LASTP SVE2 instructions

Looks like I didn't have Wilco's recent r17-843-ge6c1179fd40d1c
when re-testing some parts of the SVE2.2 series, which led to a few
check-function-bodies mismatches discovered by the Linaro CI[0].  The fix
here is to adapt the tests by changing x0 to w0 in the expected
codegen whenever the constant value is unsigned in
aarch64/sve2/acle/general/{first,last}p.c.

Pushing to trunk as obvious.

	* gcc.target/aarch64/sve2/acle/general/firstp.c: Adjust testcases.
