Chandler Carruth 9b3b286247 Fix PR16687 where we were incorrectly promoting an alloca that had ... pending speculation for a phi node. The problem here is that we were using growth of the specluation set as an indicator of whether speculation would occur, and if the phi node is already in the set we don't see it grow. This is a symptom of the fact that this signal is a total hack. Unfortunately, I couldn't really come up with a non-hacky way of signaling that promotion remains valid *after* speculation occurs, such that we only speculate when all else looks good for promotion. In the end, I went with at least a much more explicit approach of doing the work of queuing inside the phi and select processing and setting a preposterously named flag to convey that we're in the special state of requiring speculating before promotion. Thanks to Richard Trieu and Nick Lewycky for the excellent work reducing a testcase for this from a pretty giant, nasty assert in a big application. =] The testcase was excellent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187029 91177308-0d34-0410-b5e6-96231b3b80d8		2013-07-24 09:47:28 +00:00

Vectorize	When we vectorize across multiple basic blocks we may vectorize PHINodes that create a cycle. We already break the cycle on phi-nodes, but arithmetic operations are still uplicated. This patch adds code that checks if the operation that we are vectorizing was vectorized during the visit of the operands and uses this value if it can.	2013-07-22 22:18:07 +00:00
