2006-03-17Remove BRTWOWAY*Nate Begeman
Make the PPC backend not dependent on BRTWOWAY_CC and make the branch selector smarter about the code it generates, fixing a case in the readme. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26814 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-09Add support for 'special' llvm globals like debug info and static ctors/dtors.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26628 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-05Copysign needs to be expanded everywhere. Note that Alpha and IA64 shouldChris Lattner
implement copysign as a native op if they have it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26541 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-27Don't print constant initializers, they may span lines now.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26403 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-21The HasNoV9 hack isn't needed here, now that tblgen knows that ↵Chris Lattner
CustomDAGSchedInserter instructions are expensive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26298 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-17kill ADD_PARTS & SUB_PARTS and replace them with fancy new ADDC, ADDE, SUBCNate Begeman
and SUBE nodes that actually expose what's going on and allow for significant simplifications in the targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26255 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-16Rework the SelectionDAG-based implementations of SimplifyDemandedBitsNate Begeman
and ComputeMaskedBits to match the new improved versions in instcombine. Tested against all of multisource/benchmarks on ppc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26238 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-15Sparc actually *DOES* have a directive for emitting zeros. In fact, it requiresChris Lattner
it, because this: .bss X: .byte 0 results in the assembler warning: "initialization in bss segment". Annoying. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26204 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-15Fix SingleSource/Regression/C/2004-08-12-InlinerAndAllocas.c on Sparc.Chris Lattner
The ABI specifies that there is a register save area at the bottom of the stack, which means the actual used pointer needs to be an offset from the subtracted value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26202 91177308-0d34-0410-b5e6-96231b3b80d8

2006-02-09Adjust to MachineConstantPool interface change: instead of keeping aChris Lattner

2006-02-04Custom lower VAARG for the case when we are doing vaarg(double). In thisChris Lattner
case, the double being loaded may not be 8-byte aligned, so we have to use our standard bit_convert game. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25967 91177308-0d34-0410-b5e6-96231b3b80d8

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
