2011-08-16A few places where we want to skip the landingpad instruction for insertion.Bill Wendling

2011-08-16Fix handling of double precision loads and stores when Mips1 is targeted. Akira Hatanaka
Mips1 does not support double precision loads or stores, therefore two single precision loads or stores must be used in place of these instructions. This patch treats double precision loads and stores as if they are legal instructions until MCInstLowering, instead of generating the single precision instructions during instruction selection or Prolog/Epilog code insertion. Without the changes made in this patch, llc produces code that has the same problem described in r137484 or bails out when MipsInstrInfo::storeRegToStackSlot or loadRegFromStackSlot is called before register allocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137711 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-16After talking with Bill, it seems like the LandingPad handling here is likelyEli Friedman
to be wrong (or at least somewhat suspect). Leave a FIXME for Bill. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137694 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-15Update SimplifyCFG for atomic operations.Eli Friedman
This commit includes a mention of the landingpad instruction, but it's not changing the behavior around it. I think the current behavior is correct, though. Bill, can you double-check that? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137691 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-15Reorder declarations of vmovmskp* and also put the necessary AVXBruno Cardoso Lopes
predicate and TB encoding fields. This fix the encoding for the attached testcase. This fixes PR10625. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137684 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-15Continue to hoist uses of getCompileUnit() up. The goal is to get rid of ↵Devang Patel
uses of getCompileUnit(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137683 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-15Avoid evaluating Neon macro arguments more than once by disabling type checks.Bob Wilson
It turns out that the use of "__extension__" in these macros was disabling the expected "incompatible pointer" warnings, so these type checks were not doing anything anyway. They introduced a serious bug by evaluating some macro arguments twice, which is a big problem for arguments with side effects. I'll have to find another way to get the right type checking.

2011-08-15MCTargetAsmParser target match predicate support.Jim Grosbach
Allow a target assembly parser to do context sensitive constraint checking on a potential instruction match. This will be used, for example, to handle Thumb2 IT block parsing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137675 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-15This is somewhat déjà-vu, but avoid using getCompileUnit() as much as ↵Devang Patel
possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137668 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-15Add some comments here because the lack of a check for volatile/atomic here ↵Eli Friedman
is a bit unusual. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137662 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-15Fix PR10656. It's only profitable to use 128-bit inserts and extractsBruno Cardoso Lopes

2011-08-15There is no need to maintain a set to keep track of variables that use ↵Devang Patel
location expressions. In such cases, AT_location attribute's value will be a label. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137659 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-15Duncan pointed out that the LandingPadInst might read memory. (It might alsoBill Wendling
