2011-05-21Revert "InstCombine: Turn mul.with.overflow(X, 2) into the cheaper ↵Benjamin Kramer
add.with.overflow(X, X)" It's better to do this in codegen, mul.with.overflow(X, 2) is more canonical because it has only one use on "X". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131798 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-20indvars: Prototyping Sign/ZeroExtend elimination without canonical IVs.Andrew Trick
No functionality enabled by default. Use -disable-iv-rewrite. Extended IVUsers to keep track of the phi that represents the users' IV. Added the WidenIV transform to replace a narrow IV with a wide IV by doing a one-for-one replacement of IV users instead of expanding the SCEV expressions. [sz]exts are removed and truncs are inserted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131744 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-18Start trying to make InstCombine preserve more debug info. The idea here is ↵Eli Friedman
to set the debug location on the IRBuilder, which will be then right location in most cases. This should magically give many transformations debug locations, and fixing places which are missing a debug location will usually just means changing the code creating it to use the IRBuilder. As an example, the change to InstCombineCalls catches a common case where a call to a bitcast of a function is rewritten. Chris, does this approach look reasonable? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131516 91177308-0d34-0410-b5e6-96231b3b80d8
