2013-03-29Implement FRINT lowering on PPC using frinHal Finkel
Like nearbyint, rint can be implemented on PPC using the frin instruction. The complication comes from the fact that rint needs to set the FE_INEXACT flag when the result does not equal the input value (and frin does not do that). As a result, we use a custom inserter which, after the rounding, compares the rounded value with the original, and if they differ, explicitly sets the XX bit in the FPSCR register (which corresponds to FE_INEXACT). Once LLVM has better modeling of the floating-point environment we should be able to (often) eliminate this extra complexity. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178362 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-29Add PPC FP rounding instructions fri[mnpz]Hal Finkel
These instructions are available on the P5x (and later) and on the A2. They implement the standard floating-point rounding operations (floor, trunc, etc.). One caveat: frin (round to nearest) does not implement "ties to even", and so is only enabled in fast-math mode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178337 91177308-0d34-0410-b5e6-96231b3b80d8

- RDRAND always clears the destination value when a random value is not available (i.e. CF == 0). This value is truncated or zero-extended as the false boolean value to be returned.

2013-03-28Skip moving call address loading into callseq when targets prefer register ↵Michael Liao
indirect call. To enable a load of a call address to be folded with that call, this load is moved from outside of callseq into callseq. Such a moving adds a non-glued node (that load) into a glued sequence. This non-glue load is only removed when DAG selection folds them into a memory form call instruction. When such instruction selection is disabled, it breaks DAG schedule. To prevent that, such moving is disabled when target favors register indirect call. Previous workaround disabling CALL32m/CALL64m insn selection is removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178308 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-28Only enable 64-bit bswap DAG combines for PPC64Hal Finkel
Compiling in 32-bit mode on a P7 would assert after 64-bit DAG combines were added for bswap with load/store. This is because these combines are really only valid in 64-bit mode, regardless of the CPU (and this was not being checked). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178286 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-28Non optimizable objc_retainBlock calls are not forwarding.Michael Gottesman
Since we handle optimizable objc_retainBlocks through strength reduction in OptimizableIndividualCalls, we know that all code after that point will only see non-optimizable objc_retainBlock calls. IsForwarding is only called by functions after that point, so it is ok to just classify objc_retainBlock as non-forwarding. <rdar://problem/13249661>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178285 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-28[ObjCARC] Strength reduce objc_retainBlock -> objc_retain if the ↵Michael Gottesman
objc_retainBlock is optimizable. If an objc_retainBlock has the copy_on_escape metadata attached to it AND if the block pointer argument only escapes down the stack, we are allowed to strength reduce the objc_retainBlock to to an objc_retain and thus optimize it. Current there is logic in the ARC data flow analysis to handle this case which is complicated and involved making distinctions in between objc_retainBlock and objc_retain in certain places and considering them the same in others. This patch simplifies said code by: 1. Performing the strength reduction in the initial ARC peephole analysis (ObjCARCOpts::OptimizeIndividualCalls). 2. Changes the ARC dataflow analysis (which runs after the peephole analysis) to consider all objc_retainBlock calls to not be optimizable (since if the call was optimizable, we would have strength reduced it already). This patch leaves in the infrastructure in the ARC dataflow analysis to handle this case, which due to 2 will just be dead code. I am doing this on purpose to separate the removal of the old code from the testing of the new code. <rdar://problem/13249661>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178284 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-28Use direct types in most PowerPC Altivec instructions and patterns.Bill Schmidt
This follows up Ulrich Weigand's work in PPCInstrInfo.td and PPCInstr64Bit.td by doing the corresponding work for most of the Altivec patterns. I have not been able to do anything for the following classes of instructions: (1) Vector logicals. These don't have corresponding intrinsics and don't have a single obvious vector type. So far as I can tell I need to leave these as VRRC. Affected instructions are: VAND, VANDC, VNOR, VOR, VXOR, V_SET0. (2) Instructions that make use of vector shuffle. The selection code promotes all shuffles to v16i8, so any pattern that matches on a shuffle is constrained. I haven't found any way to make the patterns match on their natural types, so I plan to leave these as VRRC. Affected instructions are: VMRG*, VSPLTB, VSPLTH, VSPLTW, VPKUHUM, VPKUWUM. No change in behavior is anticipated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178277 91177308-0d34-0410-b5e6-96231b3b80d8
