[llvm-commits] [PATCH]: PowerPC64 register/instruction fixes

[Roman Divacky]

Hi there!

The attached patch fixes a few places where 32bit register classes
or instructions are used on PowerPC64.

This lets me compile a working "vim" at -O0 on PowerPC64/FreeBSD. Previously
it would crash the compiler with 

        llvm_unreachable("Impossible reg-to-reg copy");


As it was mixing 64 bit registers with 32bit ones. Vim compiled with -O2
still crashes.


OK to commit?
