Chris Lattner	cc3035e989	Now that we have operand info for machine instructions, use it to create ... temporary registers for things that define a register. This allows dag->dag isel to compile this: int %test() { ret int 65535 } into: _test: lis r2, 0 ori r2, r2, 65535 blr Next up, getting CopyFromReg to work, allowing arguments and cross-bb values. llvm-svn: 22932	2005-08-19 20:45:43 +00:00

Chris Lattner	d342de9aaa	Implement the first chunk of a code emitter. This is sophisticated enough to ... codegen: _empty: .LBB_empty_0: ; blr but can't do anything more (yet). :) llvm-svn: 22876	2005-08-18 20:07:59 +00:00
