History

Chris Lattner 0284628e8e Fix several bugs in 'op x, imm' handling. Foremost is that we now emit addi r3, r3, -1 instead of addi r3, r3, 1 for 'sub int X, 1'. Secondarily, this fixes several cases where we could crash given an unsigned constant. And fixes a couple of minor missed optimization cases, such as xor X, ~0U -> not X git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18379 91177308-0d34-0410-b5e6-96231b3b80d8		2004-11-30 07:30:20 +00:00

TODO:
* poor switch statement codegen
* load/store to alloca'd array or struct.
* implement not-R0 register GPR class
* implement scheduling info
* implement do-loop pass
* implement do-loop -> bdnz transform
* implement powerpc-64 for darwin
* implement powerpc-64 for aix
* use stfiwx in float->int
* should hint to the branch select pass that it doesn't need to print the
  second unconditional branch, so we don't end up with things like:
	b .LBBl42__2E_expand_function_8_674	; loopentry.24
	b .LBBl42__2E_expand_function_8_42	; NewDefault
	b .LBBl42__2E_expand_function_8_42	; NewDefault

Currently failing tests that should pass:
