[llvm-commits] [llvm] r170246 - /llvm/trunk/lib/Transforms/IPO/PassManagerBuilder.cpp

[NAKAMURA Takumi]

Nadav, I have reverted it again.

On x86-64, stage1 clang (generated by host g++) crashes to compile
ADT/VariadicFunctionTest.cpp.
http://bb.pgr.jp/builders/clang-3stage-x86_64-linux/builds/292

On i686, stage2 clang miscompiles bunch of files.
http://bb.pgr.jp/builders/clang-3stage-cygwin/builds/133

I'll investigate too, (if I had a time).
