2006-01-11Use Evan's outflag stuff to implement V8cmpicc. This allows us to write aChris Lattner
pattern for SUBCCrr, and makes it trivial to add support for SUBCCri, eliminating an instruction in the common "setcc X, imm" case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25212 91177308-0d34-0410-b5e6-96231b3b80d8

2005-12-26Added field noResults to Instruction.Evan Cheng
Currently tblgen cannot tell which operands in the operand list are results so it assumes the first one is a result. This is bad. Ideally we would fix this by separating results from inputs, e.g. (res R32:$dst), (ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding 'let noResults = 1' is the workaround to tell tblgen that the instruction does not produces a result. It works for now since tblgen does not support instructions which produce multiple results. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25017 91177308-0d34-0410-b5e6-96231b3b80d8
2005-12-23* Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead.Evan Cheng
* Added a pseudo instruction (for each target) that represent "return void". This is a workaround for lack of optional flag operand (return void is not lowered so it does not have a flag operand.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24997 91177308-0d34-0410-b5e6-96231b3b80d8

For example, instead of emitting this: test: save -40112, %o6, %o6 ;; imm too large add %i6, -40016, %o0 ;; imm too large call caller nop restore %g0, %g0, %g0 retl nop emit this: test: sethi 4194264, %g1 or %g1, 848, %g1 save %o6, %g1, %o6 sethi 4194264, %g1 add %g1, %i6, %g1 add %i1, 944, %o0 call caller nop restore %g0, %g0, %g0 retl nop which doesn't cause the assembler to barf. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24880 91177308-0d34-0410-b5e6-96231b3b80d8

Improve codegen by emitting [FP+92], instead of emitting a copy of FP into another GPR which wouldn't be coallesced because FP isn't register allocated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24859 91177308-0d34-0410-b5e6-96231b3b80d8
