2005-08-25Remove option to make SetCC illegal on PowerPC after long discussion withNate Begeman
Chris. This will be accomplished through correctly modeling CR's and subregs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23056 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-25LFS/STFS load and store FP values, not integer ones. This change allows usChris Lattner
to codegen this: float foo() { return 1.245; } into this: _foo: lis r2, ha16(.CPI_foo_0) lfs f1, lo16(.CPI_foo_0)(r2) blr instead of this: _foo: lis r2, ha16(.CPI_foo_0) lfs r2, lo16(.CPI_foo_0)(r2) <-- ouch or f1, r2, r2 <-- ouch blr with the dag isel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23033 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-24Remove some dead cases.Chris Lattner
Emit the indcall sequence as: mtctr inreg mr R12, inreg btctr If inreg and R12 aren't coallesced, this reduces the odds of having the mtctr and btctr in the same dispatch group. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23023 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-22Nate noticed that 30% of the malloc/frees in llc come from calls to ↵Chris Lattner
LowercaseString in the asmprinter. This changes the .td files to use lower case register names, avoiding the need to do this call. This speeds up the asmprinter from 1.52s to 1.06s on kc++ in a release build. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22974 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-21Simplify the logic for BRTWOWAY_CC handling. The isel code alreadyChris Lattner
simplifies BRTWOWAY into BR if one of the results is a fall-through. Unless I'm missing something, there is no reason to duplicate this in the target-specific code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22952 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-21If the false value for a select_cc is really simple (has no inputs), evaluateChris Lattner
it in the block. This codegens: int %test(bool %c) { %retval = select bool %c, int 17, int 1 ret int %retval } as: _test: rlwinm r2, r3, 0, 31, 31 li r2, 17 cmpwi cr0, r3, 0 bne .LBB_test_2 ; .LBB_test_1: ; li r2, 1 .LBB_test_2: ; or r3, r2, r2 blr instead of: _test: rlwinm r2, r3, 0, 31, 31 li r2, 17 li r4, 1 cmpwi cr0, r3, 0 bne .LBB_test_2 ; .LBB_test_1: ; or r2, r4, r4 .LBB_test_2: ; or r3, r2, r2 blr ... which is one fewer instruction. The savings are more significant for global address and constantfp nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22946 91177308-0d34-0410-b5e6-96231b3b80d8
