llvm-mirror/test/Transforms/LoopUnroll
Andrew Trick 4f0b3bb42b 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.
