2010-10-29Be more strict on when we produce an undefined reference. In gas a file withRafael Espindola
just .type foo,@object will produce an undefined reference to foo. On the other hand, a file with just .weakref bar, foo will not. It is somewhat hard to support both in MC since both statements should create the symbols. It should be possible if we really need to by adding to the flags, but hopefully that is not necessary. With this patch we do not produce a undefined reference in any of those cases. The assembly file needs an actual use for the undefined reference to be present. This is in preparation for a patch implementing .weakref. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117735 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-29Change instcombine's getShuffleMask to represent undef with negative values.Bob Wilson
This code had previously used 2*N, where N is the mask length, to represent undef. That is not safe because the shufflevector operands may have more than N elements -- they don't have to match the result type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117721 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-29Make instcombine a little more aggressive in combining vector shuffles.Bob Wilson
Allow splats even if they don't match either of the original shuffles, possibly due to undef entries in the shuffles masks. Radar 8597790. Also fix some 80-column violations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117719 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-29Give up on doing in-line instruction simplification during correlated value ↵Owen Anderson
propagation. Instruction simplification needs to be guaranteed never to be run on an unreachable block. However, earlier block simplifications may have changed the CFG to make block that were reachable when we began our iteration unreachable by the time we try to simplify them. (Note that this also means that our depth-first iterators were potentially being invalidated). This should not have a large impact on code quality, since later runs of instcombine should pick up these simplifications. Fixes PR8506. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117709 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-29Avoiding overly aggressive latency scheduling. If the two nodes share anEvan Cheng
operand and one of them has a single use that is a live out copy, favor the one that is live out. Otherwise it will be difficult to eliminate the copy if the instruction is a loop induction variable update. e.g. BB: sub r1, r3, #1 str r0, [r2, r3] mov r3, r1 cmp bne BB => BB: str r0, [r2, r3] sub r3, r3, #1 cmp bne BB This fixed the recent 256.bzip2 regression. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117675 91177308-0d34-0410-b5e6-96231b3b80d8
