[LLVMdev] MCJIT RemoteMemoryManager Failures on ARM

[Renato Golin]

Hi Andrew & Takumi,

I'm including you guys because you seem to know what should and what
shouldn't work, given your recent changes to the XFAILs. Feel free to
exclude yourselves, or include other folks.

I'm having a problem with a self-hosting ARM bot described here:

http://llvm.org/bugs/show_bug.cgi?id=18057

Basically, allocateSpace() sometimes works, sometimes doesn't. I couldn't
see much wrong with the code, and the call graph looks valid, so I'm
guessing it's something in the higher logic (message passing) that is
non-deterministically failing.

I even tried to run manually several times in a row and sometimes it fails,
sometimes it doesn't, so it's not a hard error in code generation, but the
GCC generated binary NEVER fails, while the Clang generated ones, sometimes
do.

I want to introduce a self-hosting buildbot on ARM, but this is stopping me
from doing so, since the tests fail randomly at every run. Any ideas?

Thanks,
--renato
