* fix a bug where we had an implicit assumption that theChris Lattner2010-11-063-2/+26

* Reimplement BuildResultOperands to be in terms of the result instruction'sChris Lattner2010-11-063-26/+20
| | | | | | | | | | | | | | | | | | | 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

Rather than trying to propagate this information maximally in all the code that using the calling convention stuff, I chose to do a mainly low impact change instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118167 91177308-0d34-0410-b5e6-96231b3b80d8

* Completely reject instructions that have an operand in theirChris Lattner2010-11-021-18/+12
| | | | | | | | | | | | | | ins/outs list that isn't specified by their asmstring. Previously the asmmatcher would just force a 0 register into it, which clearly isn't right. Mark a bunch of ARM instructions that use this as isCodeGenOnly. Some of them are clearly pseudo instructions (like t2TBB) others use a weird hasExtraSrcRegAllocReq thing that will either need to be removed or the asmmatcher will need to be taught about it (someday). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118119 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | filling them in one at a time. Previously this iterated over the asmoperands, which left the problem of "holes". The new approach simplifies things. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118104 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | merging it into a Token field in Operand, and moving the first token to an explicit mnemonic field. These were parallel arrays before (except for the mnemonic) which kept confusing me. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118024 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement enough of the missing instalias support to getChris Lattner2010-11-013-10/+18
| | | | | | | | | | | | | | | | | | | | aliases installed and working. They now work when the matched pattern and the result instruction have exactly the same operand list. This is now enough for us to define proper aliases for movzx and movsx, implementing rdar://8017633 and PR7459. Note that we do not accept instructions like: movzx 0(%rsp), %rsi GAS accepts this instruction, but it doesn't make any sense because we don't know the size of the memory operand. It could be 8/16/32 bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117901 91177308-0d34-0410-b5e6-96231b3b80d8
