[LLVMdev] Performance regression on ARM

[Renato Golin]

Folks,

First win of the benchmark buildbot!

http://llvm.org/perf/db_default/v4/nts/graph?plot.0=49.128.2&highlight_run=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,
