This is using LLVM for x86-32 on Ubuntu Feisty.

I hesitate to even report this bug because the crash is on bogus code -- I was
using LLVM for x86 to (mis)compile some C that contains AVR-specific inline
asm.  But anyway:

[regehr at babel tmp6]$  llvm-gcc -S -O0 small.c 
cc1: SelectionDAGISel.cpp:4184: void
llvm::SelectionDAGLowering::visitInlineAsm(llvm::CallSite): Assertion
`(OpInfo.ConstraintType == TargetLowering::C_RegisterClass ||
OpInfo.ConstraintType == TargetLowering::C_Register) && "Unknown constraint
type!"' failed.
small.c:6: internal compiler error: Aborted
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://developer.apple.com/bugreporter> for instructions.

[regehr at babel tmp6]$ cat small.c
int *foo;

void hello (void)
{
  __asm__ ("lpm %0, Z"::"z"(foo));
}
