* The accumulator tail recursion transform claims to work for any associativeDuncan Sands2010-07-101-14/+14
| | | | | | | | | | | | | | | | operation, but the way it's implemented requires the operation to also be commutative. So add a check for commutativity (and tweak the corresponding comments). This makes no difference in practice since every associative LLVM instruction is also commutative! Here's an example to show the need for commutativity: the accum_recursion.ll testcase calculates the factorial function. Before the transformation the result of a call is ((((1*1)*2)*3)...)*x while afterwards it is (((1*x)*(x-1))...*2)*1 which clearly requires both associativity and commutativity of * to be equal to the original. llvm-svn: 108056
* Emit COPY instructions instead of using copyRegToReg in InstrEmitter,Jakob Stoklund Olesen2010-07-104-53/+21
| | | | | | | | | ScheduleDAGEmit, TwoAddressLowering, and PHIElimination. This switches the bulk of register copies to using COPY, but many less used copyRegToReg calls remain. llvm-svn: 108050

* Don't emit st(0)/st(1) copies as FpMOV instructions. Use FpSET_ST? instead.Jakob Stoklund Olesen2010-07-102-83/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on a patch by Rafael Espíndola. Attempt to make the FpSET_ST1 hack more robust, but we are still relying on FpSET_ST0 preceeding it. This is only for supporting really weird x87 inline asm. We support: FpSET_ST0 INLINEASM FpSET_ST0 FpSET_ST1 INLINEASM with and without kills on the arguments. We don't support: FpSET_ST1 FpSET_ST0 INLINEASM nor FpSET_ST1 INLINEASM Just Don't Do It! llvm-svn: 108047

* Reapply bottom-up fast-isel, with several fixes for x86-32:Dan Gohman2010-07-1026-392/+776
| | | | | | | | | - Check getBytesToPopOnReturn(). - Eschew ST0 and ST1 for return values. - Fix the PIC base register initialization so that it doesn't ever fail to end up the top of the entry block. llvm-svn: 108039
* An x86 function returns a floating point value in st(0), and we must make sureJakob Stoklund Olesen2010-07-101-18/+26
| | | | | | | | | it is popped, even if it is ununsed. A CopyFromReg node is too weak to represent the required sideeffect, so insert an FpGET_ST0 instruction directly instead. This will matter when CopyFromReg gets lowered to a generic COPY instruction. llvm-svn: 108037

* Start the support for AVX instructions with 256-bit %ymm registers. A couple ofBruno Cardoso Lopes2010-07-0911-18/+199
| | | | | | | | | | | | | | | notes: - The instructions are being added with dummy placeholder patterns using some 256 specifiers, this is not meant to work now, but since there are some multiclasses generic enough to accept them, when we go for codegen, the stuff will be already there. - Add VEX encoding bits to support YMM - Add MOVUPS and MOVAPS in the first round - Use "Y" as suffix for those Instructions: MOVUPSYrr, ... - All AVX instructions in X86InstrSSE.td will move soon to a new X86InstrAVX file. llvm-svn: 107996
* Change TII::foldMemoryOperand API to require the machine instruction to beJakob Stoklund Olesen2010-07-096-38/+37
| | | | | | | | | | | | | | inserted in a MBB, and return an already inserted MI. This target API change is necessary to allow foldMemoryOperand to call storeToStackSlot and loadFromStackSlot when folding a COPY to a stack slot reference in a target independent way. The foldMemoryOperandImpl hook is going to change in the same way, but I'll wait until COPY folding is actually implemented. Most targets only fold copies and won't need to specialize this hook at all. llvm-svn: 107991
