[LLVMdev] [cfe-dev] ARM failures

The obvious difference is that you're using --enable-optimized and implicitly --disable-assertions. If you run the tests with

make check-all VERBOSE=1 'LIT_ARGS=-v ' > logfile

and grep for FAILED in logfile, does what's listed there give any more details? (Quite possible in a Release-Asserts build
it might not.)

It is interesting that I don't see this on my ARM box.  Instead I see these:

Failing Tests (5):
    LLVM :: ExecutionEngine/MCJIT/2003-01-04-ArgumentBug.ll
    LLVM :: ExecutionEngine/MCJIT/pr13727.ll
    LLVM :: ExecutionEngine/MCJIT/test-common-symbols.ll
    LLVM :: ExecutionEngine/MCJIT/test-fp-no-external-funcs.ll
    LLVM :: ExecutionEngine/MCJIT/test-fp.ll

I configure with:
--with-cpu=cortex-a9 --with-fpu=neon
--with-float=hard --enable-optimized

$ cat /proc/cpuinfo
Processor       : ARMv7 Processor rev 0 (v7l)
processor       : 0
BogoMIPS        : 1992.29

processor       : 1
BogoMIPS        : 1992.29

Features        : swp half thumb fastmult vfp edsp vfpv3 vfpv3d16
CPU implementer : 0x41
CPU architecture: 7
CPU variant     : 0x1
CPU part        : 0xc09
CPU revision    : 0

Any ideas?
