There is an opportunity to compute precise trip counts for 'or' expressions and multi-exit loops. rdar:14038809: Optimize trip count computation for multi-exit loops. To do this we need to record the fact that ExitLimit assumes NSW. When it does not we can safely assume that the loop trip count is the minimum ExitLimt across all subexpressions and loop exits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183060 91177308-0d34-0410-b5e6-96231b3b80d8 git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_33@183066 91177308-0d34-0410-b5e6-96231b3b80d8 Revert the test moves from 176733.

Move some of the FastISel stats that were moved under DEBUG() back out of DEBUG(), since stats are disabled across the board now. Many tests depend on grepping "-stats" output. Move those into a orig_dir/Stats/. so that they can be marked as unsupported when building without statistics.

If a function contains a noduplicate call, the call cannot be duplicated - Jump threading, loop unrolling, loop unswitching, and loop rotation are inhibited if they would duplicate the call. 2012-12-20T16:04:27Z James Molloy james.molloy@arm.com 2012-12-20T16:04:27Z urn:sha1:67ae13575900e8efd056672987249fd0adbf5e73 Similarly inlining of the function is inhibited, if that would duplicate the call (in particular inlining is still allowed when there is only one callsite and the function has internal linkage). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170704 91177308-0d34-0410-b5e6-96231b3b80d8 getSmallConstantTripMultiple should never return zero. 2012-10-24T19:46:44Z Hal Finkel hfinkel@anl.gov 2012-10-24T19:46:44Z urn:sha1:8c65549318950ff3fc1cb3d7a73fb50c688c78a5 When the trip count is -1, getSmallConstantTripMultiple could return zero, and this would cause runtime loop unrolling to assert. Instead of returning zero, one is now returned (consistent with the existing overflow cases).
