2011-08-17Allow the MCDisassembler to return a "soft fail" status code, indicating an ↵Owen Anderson
instruction that is disassemblable, but invalid. Only used for ARM UNPREDICTABLE instructions at the moment. Patch by James Molloy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137830 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-17Introduce matching patterns for vbroadcast AVX instruction. The idea is toBruno Cardoso Lopes
match splats in the form (splat (scalar_to_vector (load ...))) whenever the load can be folded. All the logic and instruction emission is working but because of PR8156, there are no ways to match loads, cause they can never be folded for splats. Thus, the tests are XFAILed, but I've tested and exercised all the logic using a relaxed version for checking the foldable loads, as if the bug was already fixed. This should work out of the box once PR8156 gets fixed since MayFoldLoad will work as expected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137810 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-17Now that we have a canonical way to handle 256-bit splats:Bruno Cardoso Lopes
vinsertf128 $1 + vpermilps $0, remove the old code that used to first do the splat in a 128-bit vector and then insert it into a larger one. This is better because the handling code gets simpler and also makes a better room for the upcoming vbroadcast! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137807 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-16Extend the undef ^ undef idiom once more. No testcase: I can't figure out ↵Eli Friedman
how to actually trigger the codepath in question at the moment, but it might get exposed in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137781 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137779 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-16Until now all debug info MDNodes referred to a root MDNode, a compile unit. ↵Devang Patel
This simplified handling of these needs in dwarf writer. However, one side effect of this is that during link time optimization all these MDNodes are _not_ uniqued. In other words there will be N number of MDNodes describing "int", "char" and all other types, which would suddenly grow when each object file starts using libraries like STL. MDNodes graph structure such that compiler unit keeps track of important MDNodes and update dwarf writer to process mdnodes top-down instead of bottom up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137778 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-16A bunch of misc fixes to SCCPSolver::ResolvedUndefsIn, including a fix to stopEli Friedman
making random bad assumptions about instructions which are not explicitly listed. Includes fix for rdar://9956541, a version of "undef ^ undef should return 0 because it's easier than arguing with users". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137777 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-16Minor bug in SCCP found by inspection. (I don't think it's possible to hit ↵Eli Friedman
this with a normal pass pipeline, but fixing for completeness.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137755 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-16ARM thumb assembly parsing for arithmetic flag setting instructions.Jim Grosbach
Thumb one requires that many arithmetic instruction forms have an 'S' suffix. For Thumb2, the whether the suffix is required or precluded depends on whether the instruction is in an IT block. Use target parser predicates to check for these sorts of context-sensitive constraints. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137746 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-16Use the getFirstInsertionPt() method instead of getFirstNonPHI + an 'isa<>'Bill Wendling
check for a LandingPadInst. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137745 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-16Add getFirstInsertionPt() method.Bill Wendling
getFirstInsertionPt() returns an iterator to the first insertion point in a basic block. This is after all PHIs and any other instruction which is required to be at the top of the basic block (like LandingPadInst). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137744 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-16Remove unused Target argument from AsmParser construction methods.Jim Grosbach
The argument is unused, and is a layering violation in any case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137735 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-16Instead of always leaving the work to the generic legalizer whenBruno Cardoso Lopes
there is no support for native 256-bit shuffles, be more smart in some cases, for example, when you can extract specific 128-bit parts and use regular 128-bit shuffles for them. Example: For this shuffle: shufflevector <4 x i64> %a, <4 x i64> %b, <4 x i32> <i32 1, i32 0, i32 7, i32 6> This was expanded to: vextractf128 $1, %ymm1, %xmm2 vpextrq $0, %xmm2, %rax vmovd %rax, %xmm1 vpextrq $1, %xmm2, %rax vmovd %rax, %xmm2 vpunpcklqdq %xmm1, %xmm2, %xmm1 vpextrq $0, %xmm0, %rax vmovd %rax, %xmm2 vpextrq $1, %xmm0, %rax vmovd %rax, %xmm0 vpunpcklqdq %xmm2, %xmm0, %xmm0 vinsertf128 $1, %xmm1, %ymm0, %ymm0 ret Now we get: vshufpd $1, %xmm0, %xmm0, %xmm0 vextractf128 $1, %ymm1, %xmm1 vshufpd $1, %xmm1, %xmm1, %xmm1 vinsertf128 $1, %xmm1, %ymm0, %ymm0 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137733 91177308-0d34-0410-b5e6-96231b3b80d8
