Awesome, thanks. What about this one where the simple register allocator seems
to have an internal error:
$ llc --regalloc=simple -f aout.bc -o aout.s
llc: X86FloatingPoint.cpp:963:

[LLVMdev] llc barfing
I was playing with optimization switches to llc to see how fast I could get it
to compile but it keeps barfing. Tinkering indicates that llc barfs
particularly when -tailcallopt is given in combination with other flags. For
example, without -tailcallopt works in a couple of ways:
$ llc -O0 -f aout.bc -o aout.s
$ llc -O0 --regalloc=local -f aout.bc -o aout.s
But fails with -tailcallopt with
