These 2 testcases were originally designed for the default -march= of x86_64 so if you pass -march=native (on a target with AVX512 enabled), they will fail. It fix this, we add `-mno-sse3 -mprefer-vector-width=512` to the options to force a specific arch to the testcase.
Tested on a skylake-avx512 machine with -march=native. PR testsuite/120643 gcc/testsuite/ChangeLog: * gcc.target/i386/vect-pragma-target-1.c: Add `-mno-sse3 -mprefer-vector-width=512` to the options. * gcc.target/i386/vect-pragma-target-2.c: Likewise.
