[LLVMdev] Alternate instruction encoding for subtargets
Hello,
I have a compiler in LLVM 2.9 for the KCPM3 processor. I'd like to
create a subtarget for the new cpu version called KCPSM6. Besides a
couple of new instructions which are not important at the moment, the
KCPSM6 cpu has different instruction opcodes. Semantically the
instructions are the same, hence I'd like to keep all the lowering...
