Folks,

First win of the benchmark buildbot!

Yay!

Out of curiosity, how long has it/you been monitoring for regressions?

http://llvm.org/perf/dbdefault/v4/nts/graph?plot.0=49.128.2&highlightrun=31861 It seems mandel-2 had a huge regression a few commits ago, and based on a quick look, it may have to do with the inst combine changes. I haven't investigated yet, but this is the first time I spot regressions on test-suite, so I'd like to first congratulate the people that worked on making that a reality! Now, I'd like to have been warned of that automatically, by email, based on some simple heuristics... But that's a topic for the Performance/Benchmarking BoF in a few weeks... :) cheers, --renato
