[LLVMdev] make check-all failing 18 tests with --enable-optimized

As part of our automated testing, I'm running make check-all to watch
for failures.  One of my builds uses the --enable-optimized option to
configure. When I build the latest trunk, I'm now seeing 18 failing
tests:
    Clang :: Preprocessor/macro_paste_c_block_comment.c
    LLVM :: CodeGen/ARM/2011-05-04-MultipleLandingPadSuccs.ll
    LLVM :: CodeGen/ARM/2011-11-14-EarlyClobber.ll
    LLVM :: CodeGen/ARM/lsr-unfolded-offset.ll
    LLVM :: CodeGen/Generic/2003-05-28-ManyArgs.ll
    LLVM :: CodeGen/Generic/print-arith-fp.ll
    LLVM :: CodeGen/Thumb/2009-08-20-ISelBug.ll
    LLVM :: CodeGen/Thumb/asmprinter-bug.ll
    LLVM :: CodeGen/X86/2006-10-13-CycleInDAG.ll
    LLVM :: CodeGen/X86/2008-02-08-LoadFoldingBug.ll
    LLVM :: CodeGen/X86/2009-09-10-SpillComments.ll
    LLVM :: CodeGen/X86/2010-02-19-TailCallRetAddrBug.ll
    LLVM :: CodeGen/X86/2010-04-13-AnalyzeBranchCrash.ll
    LLVM :: CodeGen/X86/2011-10-11-SpillDead.ll
    LLVM :: CodeGen/X86/2011-10-12-MachineCSE.ll
    LLVM :: CodeGen/X86/2011-11-09-FoldImpDefs.ll
    LLVM :: CodeGen/X86/Atomics-64.ll
    LLVM :: CodeGen/X86/fold-pcmpeqd-2.ll

17 of these tests started failing with the commit r145975, "First chunk
of MachineInstr bundle support." on 12/6/2011.  I've verified that the
tests pass with commit r145974.  

The build is running on a CentOS 5.6 machine with gcc version 4.1.2.
The build process is basically:
git clone http://llvm.org/git/llvm.git source
git clone http://llvm.org/git/clang.git source/tools/clang
mkdir build
cd build
../source/configure --prefix=$(dirname $PWD)/install --enable-optimized
make
make check-all

Is anyone else seeing this?  Or are these tests known to fail in trunk
right now?

Everything is passing for me and all the buildbots are happy. How are they
failing for you?

I'm not sure what you mean.  I'm getting blocks of "Machine code
for
function" for some of the failing tests.  In other cases I'm getting
what looks like a memory dump.  I have the output from the latest run at
the following URL if that helps:

Hi Brendan,
Have you tried with -O2 instead of -O3 ?

It's strange that this had been working up until commit r145975, then. 
Any idea what that commit would have changed to break the tests again?
