On darwin x86, I'm seeing:

$ make ENABLE_OPTIMIZED=1
llvm[2]: Compiling LiveIntervalAnalysis.cpp for Release build
Assertion failed: (MVT::isInteger(LVT)), function MeetsMaxMemopRequirement, file /Volumes/mrs5/net/llvm/llvm/lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp, line 4230.
/Volumes/mrs5/net/llvm/llvm/lib/CodeGen/LiveIntervalAnalysis.cpp:1466: internal compiler error: Abort trap
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://llvm.org/bugs&gt; for instructions.

when building with llvm's gcc-4.0, anyone else seeing it? I just rebuilt my gcc-4.0 llvm tree and reinstalled it and I tried building again, no luck. Both trees are up-to-date.

Interesting, please do the following:

Use 'make ENABLE_OPTIMIZED=1 VERBOSE=1'

To get the llvm-gcc invocation that is failing. Once you have that, something like the following should reproduce it:

1. Replace -c -o foo.o with "-c foo.bc -emit-llvm"
2. Run "llc foo.bc"

If that crashes, please run "bugpoint -run-llc foo.bc" and attach the output to a bugzilla (llvm.org/bugs/). If llc doesn't crash, please attach the .ii file to a bugzilla.

Thanks Mike!
