* [AVX] Add decode support for VUNPCKLPS/D instructions, both 128-bitDavid Greene2011-02-284-30/+120
| | | | | | | | and 256-bit forms. Because the number of elements in a vector does not determine the vector type (4 elements could be v4f32 or v4f64), pass the full type of the vector to decode routines. llvm-svn: 126664

* Add branch hinting for SPU. Kalle Raiskila2011-02-284-5/+94
| | | | | | | The implemented algorithm is overly simplistic (just speculate all branches are taken)- this is work in progress. llvm-svn: 126651

* Add preliminary support for .f32 in the PTX backend.Che-Liang Chiou2011-02-285-10/+131
| | | | | | | | | | | | - Add appropriate TableGen patterns for fadd, fsub, fmul. - Add .f32 as the PTX type for the LLVM float type. - Allow parameters, return values, and global variable declarations to accept the float type. - Add appropriate test cases. Patch by Justin Holewinski llvm-svn: 126636
* The sign of an srem instruction is the sign of its dividend (the firstNick Lewycky2011-02-281-3/+13
| | | | | | | argument), regardless of the divisor. Teach instcombine about this and fix test7 in PR9343! llvm-svn: 126635
* Silence enum conversion warnings.Benjamin Kramer2011-02-271-2/+2
| | | | llvm-svn: 126578
* Legalize support for fpextend of vector. PR9309.Duncan Sands2011-02-271-0/+2

* Target/X86: Always emit "push/pop GPRs" in prologue/epilogue and emit ↵NAKAMURA Takumi2011-02-271-17/+39
| | | | | | | | "spill/reload frames" for XMMs. It improves Win64's prologue/epilogue but it would not affect ia32 and amd64 (lack of nonvolatile XMMs). llvm-svn: 126568

* Pass the graph to the DOTGraphTraits.getEdgeAttributes().Tobias Grosser2011-02-272-2/+4
| | | | | | This follows the interface of getNodeAttributes. llvm-svn: 126562

* Add some DAGCombines for (adde 0, 0, glue), which are useful to optimize ↵Benjamin Kramer2011-02-262-37/+38
| | | | | | | | | | | legalized code for large integer arithmetic. 1. Inform users of ADDEs with two 0 operands that it never sets carry 2. Fold other ADDs or ADDCs into the ADDE if possible It would be neat if we could do the same thing for SETCC+ADD eventually, but we can't do that in target independent code. llvm-svn: 126557
* Trailing whitespace.Jim Grosbach2011-02-251-5/+5

* Roll out r126425 and r126450 to see if it fixes the failures on the buildbots.Cameron Zwarich2011-02-2518-128/+6
| | | | llvm-svn: 126488
* Revert "SimplifyCFG: GEPs with just one non-constant index are also cheap."Benjamin Kramer2011-02-251-5/+3
| | | | | | | Yes, there are other types than i8* and GEPs on them can produce an add+multiply. We don't consider that cheap enough to be speculatively executed. llvm-svn: 126481
* Add patterns to use post-increment addressing for Neon VST1-lane instructions.Bob Wilson2011-02-253-11/+39
| | | | llvm-svn: 126477

* Set NumSignBits to 1 if KnownZero/KnownOne are being zero extended. In theory itCameron Zwarich2011-02-251-0/+1
| | | | | | | | is possible to do better if the high bit is set in either KnownZero/KnownOne, but in practice NumSignBits is always 1 when we are zero extending because nothing is known about that register. llvm-svn: 126465
* We only want to zero extend the existing information if the bit width isCameron Zwarich2011-02-251-1/+1
| | | | | | actually larger. llvm-svn: 126464
* Try harder to get the hint by preferring to evict hint interference.Jakob Stoklund Olesen2011-02-252-0/+5

* Each prologue may have multiple vpush instructions to store callee-savedEvan Cheng2011-02-251-2/+14
| | | | | | | | | | | D registers since the vpush list may not have gaps. Make sure the stack adjustment instruction isn't moved between them. Ditto for vpop in epilogues. Sorry, can't reduce a small test case. rdar://9043312 llvm-svn: 126457
* SimplifyCFG: GEPs with just one non-constant index are also cheap.Benjamin Kramer2011-02-241-3/+5

* Tweak the register allocator priority queue some more.Jakob Stoklund Olesen2011-02-241-10/+22
| | | | | | | | | | | | New live ranges are assigned in long -> short order, but live ranges that have been evicted at least once are deferred and assigned in short -> long order. Also disable splitting and spilling for live ranges seen for the first time. The intention is to create a realistic interference pattern from the heavy live ranges before starting splitting and spilling around it. llvm-svn: 126451
* Remove dead variable.Nick Lewycky2011-02-241-1/+1

* Restore r125595 (reverted in r126336) with modifications:Joerg Sonnenberger2011-02-243-2/+25
| | | | | | | Introduce a variable in the AsmParserExtension whether [] is valid in an expression. If it is true, parse them like (). Enable this for ELF only. llvm-svn: 126443
