Chris Lattner	0189197608	Before implementing copyfromreg, we'll implement copytoreg correctly. ... This gets us this for the previous testcase: _test: lis r2, 0 ori r3, r2, 65535 blr Note that we actually write to r3 (the return reg) correctly now :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22933 91177308-0d34-0410-b5e6-96231b3b80d8	2005-08-19 20:50:53 +00:00
Chris Lattner	4ccd406317	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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22932 91177308-0d34-0410-b5e6-96231b3b80d8	2005-08-19 20:45:43 +00:00
Chris Lattner	ca6aa2f70c	Fix computation of # operands, add a temporary hack for CopyToReg ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22896 91177308-0d34-0410-b5e6-96231b3b80d8	2005-08-19 01:01:34 +00:00
Chris Lattner	068ca15d5e	add a new -view-sched-dags option to view dags as they are sent to the scheduler. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22878 91177308-0d34-0410-b5e6-96231b3b80d8	2005-08-18 20:11:49 +00:00
Chris Lattner	2d973e45b8	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). :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22876 91177308-0d34-0410-b5e6-96231b3b80d8	2005-08-18 20:07:59 +00:00
Chris Lattner	d32b23690d	new file, obviously just a stub ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22868 91177308-0d34-0410-b5e6-96231b3b80d8	2005-08-18 18:45:24 +00:00
