Evan Cheng	9af68f56c5	Remove isImplicitDef TargetInstrDesc flag. ... llvm-svn: 48381	2008-03-15 00:19:36 +00:00
Evan Cheng	c7ef6dc2db	Remove an invalid assertion now that there are implicit virtual register operands. ... llvm-svn: 47493	2008-02-22 19:25:04 +00:00
Chris Lattner	bfffa4f21e	Simplify the side effect stuff a bit more and make licm/sinking ... both work right according to the new flags. This removes the TII::isReallySideEffectFree predicate, and adds TII::isInvariantLoad. It removes NeverHasSideEffects+MayHaveSideEffects and adds UnmodeledSideEffects as machine instr flags. Now the clients can decide everything they need. I think isRematerializable can be implemented in terms of the flags we have now, though I will let others tackle that. llvm-svn: 45843	2008-01-10 23:08:24 +00:00
Chris Lattner	9b7b3ade8f	add a mayLoad property for machine instructions, a correlary to mayStore. ... This is currently not set by anything. llvm-svn: 45748	2008-01-08 18:05:21 +00:00
Chris Lattner	ba567fa77b	split TargetInstrDesc out into its own header file. ... llvm-svn: 45696	2008-01-07 07:33:08 +00:00
