2006-02-04Two changes:Chris Lattner
1. Treat FMOVD as a copy instruction, to help with coallescing in V9 mode 2. When in V9 mode, insert FMOVD instead of FpMOVD instructions, as we don't ever rewrite FpMOVD instructions into FMOVS instructions, thus we just end up with commented out copies! This should fix a bunch of failures in V9 mode on sparc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25961 91177308-0d34-0410-b5e6-96231b3b80d8

2006-01-31treat conditional branches the same way as conditional moves (giving themChris Lattner
an operand that contains the condcode), making things significantly simpler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25840 91177308-0d34-0410-b5e6-96231b3b80d8

2006-01-30Revamp the ICC/FCC reading instructions to be parameterized in terms of theChris Lattner
SPARC condition codes, not in terms of the DAG condcodes. This allows us to write nice clean patterns for cmovs/branches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25815 91177308-0d34-0410-b5e6-96231b3b80d8

uint %test(uint %X) { %Y = call uint %llvm.ctpop.i32(uint %X) ret uint %Y } to: test: save -96, %o6, %o6 sll %i0, 0, %l0 popc %l0, %i0 restore %g0, %g0, %g0 retl nop instead of to 40 logical ops. Note the shift-by-zero that clears the top part of the 64-bit V9 register. Testcase here: CodeGen/SparcV8/ctpop.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25814 91177308-0d34-0410-b5e6-96231b3b80d8

running it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25811 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
