Enabling AVX512 via command line may cause the compiler to generate
AVX512 instructions even before the runtime CPU feature check, causing
the test to SIGILL if the CPU lacks AVX512. Extract tests to do_test
and change main to call only if __builtin_cpu_supports ("gfni") returns
true to avoid any AVX512 instructions in main:
main:
movq __cpu_features2@GOTPCREL(%rip), %rax
testb $1, (%rax)
jne .L1577
xorl %eax, %eax
ret
.L1577:
pushq %rax
call do_test
xorl %eax, %eax
popq %rdx
ret
* gcc.target/i386/shift-gf2p8affine-2.c (do_test): New function.
Extracted from main.
(main): Drop __builtin_cpu_init. Call do_test only if
__builtin_cpu_supports ("gfni") returns true.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
