[LLVMdev] slooow compiles

[John Regehr]

As part of routine testing, I run clang and llvm-gcc a lot of times. 
Something happened between r83681 and r84167 such that clang-cc and cc1 
became many hundreds of times slower when asked to perform optimizations.

Is this a known issue?  These are all release builds on Ubuntu Jaunty on 
x86.  During these long runs, memory usage creeps up slowly at maybe 1 MB 
per minute.

Thanks,

John Regehr
