[LLVMdev] Are Opcode and register mappings exposed anywhere?

[Tyler Hardin]

See the source here:
https://github.com/earl/llvm-mirror/blob/master/lib/Target/X86/InstPrinter/X86IntelInstPrinter.cpp.
It looks like getRegisterName might do what you want, but I don't know
where it's coming from. (Whether it's a function or a member of a super
class. Hopefully, if it's a member, it's public.)

PS Sorry for the duplicate, Stephen. I forgot to CC the list.
