In addition to the 3.2 and 3.1.1 releases, I also just tried GCC 3.0.4
on sparcv9 and still got the error. (Regular sparc bi-arch is
disabled in 3.0.4, so I couldn't try plain sparc with -m64.) I also
tried 2.95 but couldn't get sparcv9 to build there.
I'm content with this PR not being a "regression" and thus getting
less attention. However our release criteria state that we will test
with PIC flags too. See http://gcc.gnu.org/gcc-3.1/criteria.html
under "Regresstion Tests". I offer the report and the sparc
maintainers can decide if it warrants pursuing in 3.2.x or later on
the trunk. I'm fine with whatever they decide.

PS: Minor note, we don't have any updated 3.2.x or 3.3 criteria AFAICT.

I am reducing the priority of this bug to "medium" because it is not a
regression.

Fixing a non-regression in 3.2.1 would violate the release criteria for
point releases. I wouldn't object to an exception if we had a fix in
hand, but with 18 release-critical bugs we need to start getting real, and
looking at what to drop. And it's the release manager's decision, not the
sparc maintainer's decision.
If it were me, I'd punt this one to 3.3 and look for others to punt as
well.

Just trying to do some triage to see if we can ever have a release ...
It appears from Kaveh's comment that no one has confirmed that this
report is
even a regression. If it isn't, the priority of target/8366 should be
downgraded
and attention focused elsewhere.
Do we have any reports of this testcase working for 64-bit sparc and any
release?

sparc-sun-solaris2.7 or sparcv9-sun-solaris2.7
>Description:
I'm getting an abort with the 3.2.x prerelease on sparc-solaris2.7 running the binary from execute/loop-2d.c when compiled with -m64 -fpic -O. I also get the failure on sparcv9-solaris2.7 with just -fpic -O. The abort goes away if I remove any of those flags or change the optimization level. I've pasted the .s file in case that helps catch it by eye, it's not too long. This abort also occurs in the 3.2 release as well as the 3.1.1 release so I can't say it's a regression, however on sparcv9 it merely requires -fpic -O so I think it's worth a quick look before the next 3.2.x release if time permits and the fix is safe.
