[LLVMdev] Exception Problems

[Bill Wendling]

Hi Anton & Duncan,

When I try to compile on Darwin now, I get this:

$ /Volumes/Gir/devel/llvm/llvm-gcc-4.0.obj/gcc/xgcc <options> -o  
eh_alloc.o

Assertion failed: (false && "Couldn't find the register class"),  
function getPhysicalRegisterRegClass, file /Volumes/Gir/devel/llvm/ 
llvm.src/lib/CodeGen/SelectionDAG/ScheduleDAG.cpp, line 269.
../../../../../llvm-gcc-4.0.src/libstdc++-v3/libsupc++/eh_alloc.cc: 
182: internal compiler error: Abort trap
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://llvm.org/bugs> for instructions.
