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

Fix casts of float to unsigned long Replace STDX (store 64 bit int indexed) with STFDX (store double indexed) Fix latent bug in indexed load generation Generate indexed loads and stores in many more cases llvm-svn: 15626 2004-08-10 22:42:36 +02:00			`TODO:`
