Justin Bogner 1476756523 InstrProf: Don't keep a large sparse list around just to zero it ... The Terms vector here represented a polynomial of of all possible counters, and is used to simplify expressions when generating coverage mapping. There are a few problems with this: 1. Keeping the vector as a member is wasteful, since we clear it every time we use it. 2. Most expressions refer to a subset of the counters, so we end up iterating over a large number of zeros doing nothing a lot of the time. This updates the user of the vector to store the terms locally, and uses a sort and combine approach so that we only operate on counters that are actually used in a given expression. For small cases this makes very little difference, but in cases with a very large number of counted regions this is a significant performance fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218879 91177308-0d34-0410-b5e6-96231b3b80d8		2014-10-02 16:04:03 +00:00
