Please try to figure out why the configure test is not detecting VIS3
instruction capabilities in your assembler. That's why the VIS3 tests are
failing.
The combined-1.c test is no

Thanks, I'll add the necessary register directives and work on making the
testcases conditional on assembler support.

I would suggest against a gcc workaround, let's just fix binutils.
I have posted a fix to the binutils list for testing.

Can you multiarch a 64-bit sparc build from 32-bit rtems?
Probably not... but if that were possible you'd need to
check host_address like we do for Linux.
So, change looks fine as-i

I'll take a look at this. The branch prediction tags are guarded by either
TARGET_V9 or TARGET_ARCH64, but not TARGET_VIS.

BTW, Joel, you might want to check out "-mdebug=options" :-)

The next problem you'll run into is that the shmid additions for sparc weren't
done correctly in the patch. Where you see 's64', it should be 'long', and
where you see 'u64' it should be 'unsigned long'.

Yes, the failures mentioned in:

are the same exact ones I am seeing.

In the regex cases, glibc/posix/regexec.c:merge_state_with_log() is what
gets miscompiled.
I will attach match_good.s and match_bad.s
match_good.s is a working compile of this function, using gcc-4.3.2
match_bad.s is

I'm not passing anything special to the build, just stock "-O2" with
a 32-bit compiler.

I'm trying to distill a test case currently and also something broke bootstrap
on sparc in the past day or two (I think it's the IRA change) which I want
to track down first.
I'll play with your patch

I get the same two instruction change you saw with "0 &&" and it
makes the test pass.

Sorry, I overlooked that I'd been building with --disable-nls, I'll
rebuild with --enable-nls and see how things look after that.

I've double checked that I have the locales and everything installed.
I'm building a fixed setup now, and I validated that "gnu" instead of
"generic" is now choosen for the c++local
--- Comment #7 from davem at davemloft dot net 2010-04-03 01:51 ---
Ok, once I straightened out all of the locale issues the abi_check
failure went away. Closing.
