2011-12-30Separate the concept of having memory access in operand 4 from the concept ↵Craig Topper
of having the W bit set for XOP instructons. Removes ORing W-bits in the encoder and will similarly simplify the disassembler implementation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147366 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-30Combine FMA4 PS/PD patterns with the instruction definitions.Craig Topper

2011-12-30Change FMA4 memory forms to use memopv* instead of alignedloadv*. No need to ↵Craig Topper
force alignment on these instructions. Add a couple testcases for memory forms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147361 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-30Fix load size for FMA4 SS/SD instructions. They need to use f32 and f64 ↵Craig Topper
size, but with the special handling to be compatible with the intrinsic expecting a vector. Similar handling is already used elsewhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147360 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-30Cleanup stack/frame register define/kill states. This fixes two bugs:Hal Finkel
1. The ST*UX instructions that store and update the stack pointer did not set define/kill on R1. This became a problem when I activated post-RA scheduling (and had incorrectly adjusted the Frames-large test). 2. eliminateFrameIndex did not kill its scavenged temporary register, and this could cause the scavenger to exhaust all available registers (and its emergency spill slot) when there were a lot of CR values to spill. The 2010-02-12-saveCR test has been adjusted to check for this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147359 91177308-0d34-0410-b5e6-96231b3b80d8

instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147353 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147351 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-29Make FMA3 imply AVX needs to be enabled. Particularly because 256-bit types ↵Craig Topper
aren't valid unless AVX is enabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147349 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-29Change XOP detection to use the correct CPUID bit instead of using the FMA4 bit.Craig Topper
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147348 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-29Add FeaturePOPCNT to all CPU types that lost it was removed from SSE42/SSE4A ↵Craig Topper
in r147339. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147347 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-29Mark non-VEX forms of PCLMUL instructions as requiring SSE2 to be enabled ↵Craig Topper
along with CLMUL. That's required for the XMM registers to be valid for integer data. Doesn't change any behavior since the CLMUL instructions don't have patterns yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147345 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-29Mark non-VEX forms of AES instructions as requiring SSE2 to be enabled along ↵Craig Topper
with AES. Since that's required for the XMM registers to be valid for integer data. Doesn't change any behavior though since you can't use an intrinsic with an illegal type anyway. Just makes it consistent with the VEX forms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147344 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-29Remove the separate explicit AES instruction patterns. They are equivalent ↵Craig Topper
to the patterns specified by the instructions. Also remove unnecessary bitconverts from the AES patterns. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147342 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-29Make SSE42 and SSE4A not imply POPCNT. POPCNT should be able to be disabled ↵Craig Topper
on its own without disabling SSE4.2 or SSE4A. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147339 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-29Make LowerBUILD_VECTOR keep node vector types consistent when creating MOVL ↵Craig Topper

2011-12-29Remove trailing spaces. Fix an assert to use && instead of || before string. ↵Craig Topper
Add same assert on similar code path. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147335 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-28Change CaptureTracking to pass a Use* instead of a Value* when a value isNick Lewycky
captured. This allows the tracker to look at the specific use, which may be especially interesting for function calls. Use this to fix 'nocapture' deduction in FunctionAttrs. The existing one does not iterate until a fixpoint and does not guarantee that it produces the same result regardless of iteration order. The new implementation builds up a graph of how arguments are passed from function to function, and uses a bottom-up walk on the argument-SCCs to assign nocapture. This gets us nocapture more often, and does so rather efficiently and independent of iteration order. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147327 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-28Fixed a bug in LowerVECTOR_SHUFFLE and LowerBUILD_VECTOR.Elena Demikhovsky
Matching MOVLP mask for AVX (265-bit vectors) was wrong. The failure was detected by conformance tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147308 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-27Add handling of x86_avx2_pmovmskb to computeMaskedBitsForTargetNode for ↵Craig Topper
consistency. Add comments and an assert for BMI instructions to PerformXorCombine since the enabling of the combine is conditional on it, but the function itself isn't. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147287 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-27Teach simplifycfg to recompute branch weights when merging some branches, andNick Lewycky
to discard weights when appropriate. Still more to do (and a new TODO), but it's a start! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147286 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-27Using Inst->setMetadata(..., NULL) should be safe to remove metadata even whenNick Lewycky
there is non of that type to remove. This fixes a crasher in the particular case where the instruction has metadata but no metadata storage in the context (this is only possible if the instruction has !dbg but no other metadata info). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147285 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-24Add an explicit test that we now fold cttz.i32(..., true) >> 5 -> 0.Chandler Carruth

2011-12-24InstCombine: Add a combine that turns (2^n)-1 ^ x back into (2^n)-1 - x iff ↵Benjamin Kramer
x is smaller than 2^n and it fuses with a following add. This was intended to undo the sub canonicalization in cases where it's not profitable, but it also finds some cases on it's own. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147256 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-24ComputeMaskedBits: Make knownzero computation more aggressive for ctlz with ↵Benjamin Kramer
undef zero. unsigned foo(unsigned x) { return 31 - __builtin_clz(x); } now compiles into a single "bsrl" instruction on x86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147255 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-24InstCombine: Canonicalize (2^n)-1 - x into (2^n)-1 ^ x iff x is known to be ↵Benjamin Kramer
smaller than 2^n. This has the obvious advantage of being commutable and is always a win on x86 because const - x wastes a register there. On less weird architectures this may lead to a regression because other arithmetic doesn't fuse with it anymore. I'll address that problem in a followup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147254 91177308-0d34-0410-b5e6-96231b3b80d8
