Hi,
This is the patch to fix gcc.target/i386/auto-init-* tests.
I have tested the change at X86_64-linux with
make check-gcc
RUNTESTFLAGS='--target_board=unix\{-m64,-m64/-march=skylake-avx512,-m64/-fstack-protector-all,-m64/-fstack-clash-protection,-m32/-mno-sse,-m32/-mtune=bonnell,-m32/-march=bonnell,-m32/-fstack-protector-all/-fstack-clash-protection\}
i386.exp=auto-init*’
make check-gcc
RUNTESTFLAGS='--target_board=unix\{-m64,-m64/-march=skylake-avx512/-fPIC,-m64/-fstack-protector-all/-fPIC,-m64/-fstack-clash-protection/-fPIC,-m32/-mno-sse/-fPIC,-m32/-mtune=bonnell/-fPIC,-m32/-march=bonnell/-fPIC,-m32/-fstack-protector-all/-fstack-clash-protection/-fPIC\}
i386.exp=auto-init*’
Everything works fine.
Okay for commit?
Thanks.
Qing
**************************
testsuite: Fix gcc.target/i386/auto-init-* tests.
This set of tests failed on many different combination of -march, -mtune.
some of them failed with -fstack-protestor-all, or -mno-sse. And the
pattern matches are also different on lp64 or ia32.
The reason for these failures is that the RTL or assembly level patten
matches are only valid for -march=x86-64 -mtune=generic.
We restrict the testing only for -march=x86-64 and -mtune=generic. Also
add -fno-stack-protector or -msse for some of the testing cases.
gcc/testsuite/ChangeLog:
2021-09-17 qing zhao <[email protected]>
* gcc.target/i386/auto-init-1.c: Restrict the testing only for
-march=x86-64 and -mtune=generic. Add -fno-stack-protector.
