2006-01-30When in v9 mode, emit fabsd/fnegd/fmovdChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25810 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-30First step towards V9 instructions in the V8 backend, two conditional moveChris Lattner
patterns. This allows emission of this code: t1: save -96, %o6, %o6 subcc %i0, %i1, %l0 move %icc, %i0, %i2 or %g0, %i2, %i0 restore %g0, %g0, %g0 retl nop instead of this: t1: save -96, %o6, %o6 subcc %i0, %i1, %l0 be .LBBt1_2 ! nop .LBBt1_1: ! or %g0, %i2, %i0 .LBBt1_2: ! restore %g0, %g0, %g0 retl nop for this: int %t1(int %a, int %b, int %c) { %tmp.2 = seteq int %a, %b %tmp3 = select bool %tmp.2, int %a, int %c ret int %tmp3 } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25809 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-30Two changes:Chris Lattner
1. Default to having V9 instructions, instead of just V8. 2. unless -enable-sparc-v9-insts is passed, disable V9 (for use with llcbeta) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25807 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-30When lowering SELECT_CC, see if the input is a lowered SETCC. If so, foldChris Lattner
the two operations together. This allows us to compile this: void %two(int %a, int* %b) { %tmp.2 = seteq int %a, 0 %tmp.0.0 = select bool %tmp.2, int 10, int 20 store int %tmp.0.0, int* %b ret void } into: two: save -96, %o6, %o6 or %g0, 20, %l0 or %g0, 10, %l1 subcc %i0, 0, %l2 be .LBBtwo_2 ! entry nop .LBBtwo_1: ! entry or %g0, %l0, %l1 .LBBtwo_2: ! entry st %l1, [%i1] restore %g0, %g0, %g0 retl nop instead of: two: save -96, %o6, %o6 sethi 0, %l0 or %g0, 1, %l1 or %g0, 20, %l2 or %g0, 10, %l3 subcc %i0, 0, %l4 be .LBBtwo_2 ! entry nop .LBBtwo_1: ! entry or %g0, %l0, %l1 .LBBtwo_2: ! entry subcc %l1, 0, %l0 bne .LBBtwo_4 ! entry nop .LBBtwo_3: ! entry or %g0, %l2, %l3 .LBBtwo_4: ! entry st %l3, [%i1] restore %g0, %g0, %g0 retl nop git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25806 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
