| | | | | | | | | | | | | | | | | | | operand list instead of the operand list redundantly declared on the alias or instruction. With this change, we finally remove the ins/outs list on the alias. Before: def : InstAlias<(outs GR16:$dst), (ins GR8 :$src), "movsx $src, $dst", (MOVSX16rr8W GR16:$dst, GR8:$src)>; After: def : InstAlias<"movsx $src, $dst", (MOVSX16rr8W GR16:$dst, GR8:$src)>; This also makes the alias mechanism more general and powerful, which will be exploited in subsequent patches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118329 91177308-0d34-0410-b5e6-96231b3b80d8

* Two sets of changes. Sorry they are intermingled.Evan Cheng2010-11-032-25/+41
| | | | | | | | | | | | | | 1. Fix pre-ra scheduler so it doesn't try to push instructions above calls to "optimize for latency". Call instructions don't have the right latency and this is more likely to use introduce spills. 2. Fix if-converter cost function. For ARM, it should use instruction latencies, not # of micro-ops since multi-latency instructions is completely executed even when the predicate is false. Also, some instruction will be "slower" when they are predicated due to the register def becoming implicit input. rdar://8598427 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118135 91177308-0d34-0410-b5e6-96231b3b80d8
