| | | | | | | | | | | | use the old behavior, the flag is -O0. This change allows for finer-grained control over which optimizations are run at different -O levels. Most of this work was pretty mechanical. The majority of the fixes came from verifying that a "fast" variable wasn't used anymore. The JIT still uses a "Fast" flag. I'm not 100% sure if it's necessary to change it there... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70270 91177308-0d34-0410-b5e6-96231b3b80d8

* Teach getZeroExtendExpr and getSignExtendExpr to use trip-countDan Gohman2009-04-274-13/+769
| | | | | | | | | | | | | | | | | | information to simplify [sz]ext({a,+,b}) to {zext(a),+,[zs]ext(b)}, as appropriate. These functions and the trip count code each call into the other, so this requires careful handling to avoid infinite recursion. During the initial trip count computation, conservative SCEVs are used, which are subsequently discarded once the trip count is actually known. Among other benefits, this change lets LSR automatically eliminate some unnecessary zext-inreg and sext-inreg operation where the operand is an induction variable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70241 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | PR2957 ISD::VECTOR_SHUFFLE now stores an array of integers representing the shuffle mask internal to the node, rather than taking a BUILD_VECTOR of ConstantSDNodes as the shuffle mask. A value of -1 represents UNDEF. In addition to eliminating the creation of illegal BUILD_VECTORS just to represent shuffle masks, we are better about canonicalizing the shuffle mask, resulting in substantially better code for some classes of shuffles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70225 91177308-0d34-0410-b5e6-96231b3b80d8
