Reduce false positives for -Wnonnull for VLA parameters [PR98541]
caused
FAIL: gcc.dg/Wnonnull-4.c (test for excess errors)
with GCC configured with
../../gcc/configure --prefix=/export/users/haochenj/src/gcc-bisect/master/master/r14-5115/usr --enable-clocale=gnu --with-system-zlib --with-demangler-in-ld --with-fpmath=sse --enable-languages=c,c++,fortran --enable-cet --without-isl --enable-libmpx x86_64-linux --disable-bootstrap
To reproduce:
$ cd {build_dir}/gcc && make check RUNTESTFLAGS="dg.exp=gcc.dg/Wnonnull-4.c --target_board='unix{-m32}'"
$ cd {build_dir}/gcc && make check RUNTESTFLAGS="dg.exp=gcc.dg/Wnonnull-4.c --target_board='unix{-m32\ -march=cascadelake}'"
(Please do not reply to this email, for question about this report, contact me at haochen dot jiang at intel.com.)
(If you met problems with cascadelake related, disabling AVX512F in command line might save that.)
(However, please make sure that there is no potential problems with AVX512.)
