[PATCH] D16123: Limit number of blocks scanned for non-local dependences

[Joerg Sonnenberger via llvm-commits]

joerg added a comment.

Copying comment that didn't make into phab:

Run time in steps of 100, absolute value not necessarily stable:
2.5s 3.0s 3.3s 4.1s 4.1s 4.3s 4.8s 5.1s 5.4s 5.6s

It's not exactly surprising that the initial ramp up is mostly linear. I
simply don't know what the implications for runtime are at this point,
can't easily run LNT.
