[llvm] r229841 - Reverting r229831 due to multiple ARM/PPC/MIPS build-bot failures.

[Kuperstein, Michael M]

So, I've tried to recommit.
Quite unsurprisingly, it didn't work.

First of all, the MIPS bot is still failing, in the same way it used to:
http://lab.llvm.org:8011/builders/clang-cmake-mips/builds/5596/steps/build%20stage%201/logs/stdio

FAILED: /usr/bin/c++   -DGTEST_HAS_RTTI=0 -D_DEBUG -D_GNU_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -fPIC -fvisibility-inlines-hidden -Wall -W -Wno-unused-parameter -Wwrite-strings -Wcast-qual -Wno-missing-field-initializers -pedantic -Wno-long-long -Wno-maybe-uninitialized -Wno-comment -std=c++11 -ffunction-sections -fdata-sections -O3  -Ilib/Target/X86/MCTargetDesc -I/var/buildbot/lab.llvm.org/clang-cmake-mips/llvm/lib/Target/X86/MCTargetDesc -I/var/buildbot/lab.llvm.org/clang-cmake-mips/llvm/lib/Target/X86 -Ilib/Target/X86 -Iinclude -I/var/buildbot/lab.llvm.org/clang-cmake-mips/llvm/include    -UNDEBUG -fno-exceptions -fno-rtti -MMD -MT lib/Target/X86/MCTargetDesc/CMakeFiles/LLVMX86Desc.dir/X86MCTargetDesc.cpp.o -MF lib/Target/X86/MCTargetDesc/CMakeFiles/LLVMX86Desc.dir/X86MCTargetDesc.cpp.o.d -o lib/Target/X86/MCTargetDesc/CMakeFiles/LLVMX86Desc.dir/X86MCTargetDesc.cpp.o -c /var/buildbot/lab.llvm.org/clang-cmake-mips/llvm/lib/Target/X86/MCTargetDesc/X86MCTargetDesc.cpp

cc1plus: out of memory allocating 4072 bytes after a total of 1081843712 bytes

At least two of ARM bots are also failing - but now, in stage 1:

http://lab.llvm.org:8011/builders/clang-cmake-thumbv7-a15-full-sh/builds/948/steps/build%20stage%201/logs/stdio

command timed out: 1200 seconds without output, attempting to kill
process killed by signal 9
program finished with exit code -1
elapsedTime=3712.616572

And the same here:
http://lab.llvm.org:8011/builders/clang-native-aarch64-full/builds/1226/steps/build%20stage%201/logs/stdio

Note that at least one ARM bot *is* passing - clang-cmake-thumbv7-a15 was just fine.
Most of the self-host bots haven't finished yet, we'll see if there are more failures.

Anyway, I've reverted.

Daniel, could you please take a look at the MIPS bot again?
Renato/Richard, can you please take a look at what's going on with the ARM bots?

Thanks,
   Michael

Vaguely, yes. But since there were more direct problems with other platforms, I decided not to worry too much.

I'm a bit flooded with patch reviews and the 3.6.1 release, but I may have some time later this week.

Michael, if you have fixed the problems in other arches, you could try committing again and keep a close eye on the self-hosting bots. If things go bad again, revert and we'll check.
