Benjamin Kramer 1af132dcf3 LoopVectorizer: Emit memory checks into their own basic block. This separates the check for "too few elements to run the vector loop" from the "memory overlap" check, giving a lot nicer code and allowing to skip the memory checks when we're not going to execute the vector code anyways. We still leave the decision of whether to emit the memory checks as branches or setccs, but it seems to be doing a good job. If ugly code pops up we may want to emit them as separate blocks too. Small speedup on MultiSource/Benchmarks/MallocBench/espresso. Most of this is legwork to allow multiple bypass blocks while updating PHIs, dominators and loop info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172902 91177308-0d34-0410-b5e6-96231b3b80d8		2013-01-19 13:57:58 +00:00
