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.

Thank you.

I will commit the change soon.

For the aarch64 tests, do you have a suggestion on what the option combination I should test?
