--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> ---
These are wrong:
ifeq ($(build-mathvec),yes)
libmvec-tests += double-vlen2 double-vlen4 double-vlen4-avx2 \
float-vlen4 float-vlen8 float-vlen8-avx2
ifeq (yes,$(config-cflags-avx512))
libmvec-tests += double-vlen8 float-vlen16
endif
You can't run those tests just because compiler works. They will
fail if hardware doesn't support AVX or AVX512.

double-vlen8, float-vlen16 are AVX512 tests and they have runtime checks.
double-vlen4-avx2, float-vlen8-avx2 are AVX2 and they also have runtime checks.
test-double-vlen4, test-float-vlen8 are AVX tests, and yes, for these I didn't
add runtime checks.

Please configure glibc with --enable-hardcoded-path-in-tests and
run it under gdb to see why AVX check fails to work.
