           Summary: [v850-elf] ICE with -O2 building misc-inst.lo
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P2
         Component: bootstrap

GCC target triplet: v850-elf

Building gcc 3.3 branch for v850-elf with --disable-multibs --enable-
languages=c++ in a combined tree with cvs binutils and newlib, I get:

Changing CXXFLAGS to -O1 cures the ICE.

Just -O2 on v850-elf cc1plus makes this ICE (on 3.3 branch)

Oops, looks like safari corrupts attachments. Will send a new testcase once mainline bootstrap 
again.

Still present on 20030726 (branch). Hopefully this one isn't corrupted.

This one's still present with 3.3 branch (20030811). Nick, is this similar to 
the other v850 bug you recently fixed, I tried the patch from mainline, but it 
didn't seem to help.

However, a very similar patch (attached) does fix the problem.

I am going to have to run some bootstrap tests before this one can be
officially submitted however.

Cheers

Thanks for the patch Nick. It fixed the build failure I was seeing. Has your testing confirmed that 
this is the right patch?

It does work, but Vlad is worried about whether it is the correct
solution, so he is going to have a look at it next week.

Sure, that's fine. My only request is that this be fixed in time for 3.3.2, if at all possible. Thanks.

Already analysised by Nick and a patch created by him (might not be the correct way though).

Nick, this is still present on the branch. Is it worth fixing this on the
branch, or shall I just close this report as fixed for mainline?

I think that you should close it.  Vlad was not happy with my patch,
but did not have time to come up with a better one, and since it
affects generic code, not v850 specific, I am loathe to check it in
without approval.  The patch is archived in this test case, so we
could always add a note to the installation instructions for the 3.3
sources saying that v850 users ought to apply the patch.

Cheers
        Nick

Fixed for 3.4. Since nobody else has hollered, I don't think we should update the install docs. 
Closing.
