Andrew Trick 5d73448bb7 Add -unroll-runtime for unrolling loops with run-time trip counts. ... Patch by Brendon Cahoon! This extends the existing LoopUnroll and LoopUnrollPass. Brendon measured no regressions in the llvm test suite with -unroll-runtime enabled. This implementation works by using the existing loop unrolling code to unroll the loop by a power-of-two (default 8). It generates an if-then-else sequence of code prior to the loop to execute the extra iterations before entering the unrolled loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146245 91177308-0d34-0410-b5e6-96231b3b80d8		2011-12-09 06:19:40 +00:00
