llvm dev - Jul 2010 - [LLVMdev] LLVM ERROR: Invalid primitive type.. Is this a bug?

Hi,

I have:
int main()
{
   int i = 1;
}
in test.c.

Then:
llvm-gcc -emit-llvm -O0 -c test.c -o test.bc -g
llc -march=cpp test.bc
gives me:
LLVM ERROR: Invalid primitive type

This only happens when I use the "-g". Is this a bug?

Thanks,
Guoliang

Yes, it is a bug.  In fact LLVM from subversion from a few days ago
crashes even without -march=cpp:

$ llc test.bc
llc: llvm/include/llvm/Support/Casting.h:202: typename llvm::cast_retty<To, 
From>::ret_type llvm::cast(const Y&) [with X = llvm::MDNode, Y =
llvm::Value*]:
Assertion `isa<X>(Val) && "cast<Ty>() argument of
incompatible type!"' failed.

Please open a bugreport at http://llvm.org/bugs

Ciao,

Duncan.
