[LLVMdev] Lots of tests failing

[David A. Greene]

Hi everyone,

I just built the latest llvm/llvm-gcc yesterday and got a ton of test
failures that look like the following ([i686-off-opt] means an i686
Release build of official -- unmodified -- sources):

[i686-off-opt]: ./llvm.official/projects/llvm-test/DiffOutput.sh 
"/ptmp/dag/build.llvm.official/Release/bin/fpcmp  -r 0.016" llc sse.isamax

Anyone else seeing this?  I'm trying to commit my updated regalloc
patches but it's hard to do when the unmodified sources are failing so
badly.
