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

...A quick thing you can do is to compile with -ftime-report and compare the top few passes between versions.
