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

[Brendan Kirby]

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?
