2011-02-04Also compute interference intervals for blocks with no uses.Jakob Stoklund Olesen
When the live range is live through a block that doesn't use the register, but that has interference, region splitting wants to split at the top and bottom of the basic block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124839 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-04Verify kill flags conservatively.Jakob Stoklund Olesen
Allow a live range to end with a kill flag, but don't allow a kill flag that doesn't end the live range. This makes the machine code verifier more useful during register allocation when kill flag computation is deferred. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124838 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-03Fix coloring bug when mapping values in the middle of a live-through block.Jakob Stoklund Olesen
If the found value is not live-through the block, we should only add liveness up to the requested slot index. When the value is live-through, the whole block should be colored.

2011-02-03Improve threading of comparisons over select instructions (spotted by myDuncan Sands
auto-simplifier). This has a big impact on Ada code, but not much else. Unfortunately the impact is mostly negative! This is due to PR9004 (aka SCCP failing to resolve conditional branch conditions in the destination blocks of the branch), in which simple correlated expressions are not resolved but complicated ones are, so simplifying has a bad effect! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124788 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-03Fix PR9127 by reversing the operands even if they have more then one use.Rafael Espindola
Reversing the operands allows us to fold, but doesn't force us to. Also, at this point the DAG is still being optimized, so the check for hasOneUse is not very precise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124773 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-03Defer SplitKit value mapping until all defs are available.Jakob Stoklund Olesen
The greedy register allocator revealed some problems with the value mapping in SplitKit. We would sometimes start mapping values before all defs were known, and that could change a value from a simple 1-1 mapping to a multi-def mapping that requires ssa update. The new approach collects all defs and register assignments first without filling in any live intervals. Only when finish() is called, do we compute liveness and mapped values. At this time we know with certainty which values map to multiple values in a split range. This also has the advantage that we can compute live ranges based on the remaining uses after rematerializing at split points. The current implementation has many opportunities for compile time optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124765 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-02Changed the TableGen created MatchInstructionImpl() setting of ErrorInfo.Kevin Enderby
The algorithm for identifying which operand is invalid will now always point to some operand and not the mnemonic sometimes. The change is now that ErrorInfo is the index of the highest operand that does not match for any of the matching mnemonics records. And no longer the ~0U value when the mnemonic matches and not every record with a matching mnemonic has the same mismatching operand index. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124734 91177308-0d34-0410-b5e6-96231b3b80d8

This makes the job of the later optzn passes easier, allowing the vast amount of icmp transforms to chew on it.
