I wonder if this is related to PR 28834 at all.
The ICE stems from a new sanity check in the DWARF-2 back-end and we have
fixed the problem in Gigi.

it looks like ifcvt messes up in pass 3 and puts the post-inc in the

It's actually the combiner that wrongly ditches the post-inc, at least with

It also works fine with -O2 using my gcc 4.1 build.
It fails with svn head.

I've followed the mail lists for years while this was debated; I
don't think it's settled. (./configure; make definitely isn't
supported.)
Tempus fugit. :-)

No, really, you don't seem to understand.
If you respect these DECL_NONADDRESSABLE_P or
TYPE_NONALIASED_COMPONENT flags, you are going to make them unaliased.
Your whole bug report

I don't think this bug has anything to do with excess precision. Valgrind
shows that, when compiled at -O2, we are reading from uninitialized memory.
Confirmed:
andl-144(%ebp), %ebx --- bogus

This smells like an aliasing issue.
But it's not, it's if-conversion.

Agreed. The Ada FE should either change or prove that there is a
design/implementation flaw in the aliasing machinery.
I think we can prove that there is a discrepancy between the Tree type-based
aliasing

You need to put 'volatile' on hup_rcvd for this to work.

I have found the cause of the problem. It isn't a problem with gcc.
I use the binutils shipped with Solaris10 to strip the binaries and create
separate debug symbol files. If I do not strip g++/libstdc

PA-RISC GNU/Linux is not a primary platform, so I've marked this P5. However,
PA-RISC HP-UX is a primary platform, so if this bug manifests there, please
set
this back to P3 with an explanatory comment

Right, bootstrap has been broken because of that for ages.
I've pinged the patch many times but to no avail...

Eric's patch is http://gcc.gnu.org/ml/gcc-patches/2006-02/msg01300.html
Right, but the info is already in the Patch URL field.

The test case that has been attached shows a FORTRAN and Ada program that are
equivalent (within their matrix multiply loop). The Ada one runs about 2x
slower with about 3x the number of machine instructions
1 - 100 of 2613 matches
