2011-11-15Thumb2 assembly parsing for mul.w in IT block fix.Jim Grosbach
When the 3rd operand is not a low-register, and the first two operands are the same low register, the parser was incorrectly trying to use the 16-bit instruction encoding. rdar://10449281 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144679 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-15We currently use a callback to handle an IL pass deleting a BB that stillRafael Espindola
has a reference to it. Unfortunately, that doesn't work for codegen passes since we don't get notified of MBB's being deleted (the original BB stays). Use that fact to our advantage and after printing a function, check if any of the IL BBs corresponds to a symbol that was not printed. This fixes pr11202. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144674 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-15Rather than trying to use the loop block sequence *or* the functionChandler Carruth
block sequence when recovering from unanalyzable control flow constructs, *always* use the function sequence. I'm not sure why I ever went down the path of trying to use the loop sequence, it is fundamentally not the correct sequence to use. We're trying to preserve the incoming layout in the cases of unreasonable control flow, and that is only encoded at the function level. We already have a filter to select *exactly* the sub-set of blocks within the function that we're trying to form into a chain. The resulting code layout is also significantly better because of this. In several places we were ending up with completely unreasonable control flow constructs due to the ordering chosen by the loop structure for its internal storage. This change removes a completely wasteful vector of basic blocks, saving memory allocation in the common case even though it costs us CPU in the fairly rare case of unnatural loops. Finally, it fixes the latest crasher reduced out of GCC's single source. Thanks again to Benjamin Kramer for the reduction, my bugpoint skills failed at it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144627 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-15Break false dependencies before partial register updates.Jakob Stoklund Olesen
Two new TargetInstrInfo hooks lets the target tell ExecutionDepsFix about instructions with partial register updates causing false unwanted dependencies. The ExecutionDepsFix pass will break the false dependencies if the updated register was written in the previoius N instructions. The small loop added to sse-domains.ll runs twice as fast with dependency-breaking instructions inserted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144602 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-15Track register ages more accurately.Jakob Stoklund Olesen
Keep track of the last instruction to define each register individually instead of per DomainValue. This lets us track more accurately when a register was last written. Also track register ages across basic blocks. When entering a new basic block, use the least stale predecessor def as a worst case estimate for register age. The register age is used to arbitrate between conflicting domains. The most recently defined register wins. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144601 91177308-0d34-0410-b5e6-96231b3b80d8
