ColdBlockInfo: overhaul analysis pass #76093

kavon · 2024-08-26T23:09:58Z

The old analysis pass doesn't take into account profile data, nor does
it consider post-dominance. It primarily dealt with _fastPath/_slowPath.

A block that is dominated by a cold block is itself cold. That's true
whether it's forwards or backwards dominance.

We can also consider a call to any Never returning function as a
cold-exit, though the block(s) leading up to that call may be executed
frequently because of concurrency. For now, I'm ignoring the concurrency
case and assuming it's cold. To make use of this "no return" prediction,
use the -enable-noreturn-prediction flag, which is currently off by
default.

How to read the data

The tables contain differences in performance which are larger than 8% and differences in code size which are larger than 1%.

If you see any unexpected regressions, you should consider fixing the
regressions before you merge the PR.

Noise: Sometimes the performance results (not code size!) contain false
alarms. Unexpected regressions which are marked with '(?)' are probably noise.
If you see regressions which you cannot explain you can try to run the
benchmarks again. If regressions still show up, please consult with the
performance team (@eeckstein).

In prior runs with minor tweaks to the algorithm, the FlattenListFlatMap benchmark has either not changed, or actually improved by 19%. So, I think it's overly sensitive and at some sort of arbitrary performance cliff; the result doesn't appear significant.

The only consistent improvements I've seen over multiple benchmark runs are:

the 5.2% code-size improvement in ReversedCollections.o with -Osize
the 20% performance improvement of ReversedBidirectional with -Osize

They're related as (2) is part of the object file in (1), so my guess is the improvement is from not inlining as much into cold blocks.

The old analysis pass doesn't take into account profile data, nor does it consider post-dominance. It primarily dealt with _fastPath/_slowPath. A block that is dominated by a cold block is itself cold. That's true whether it's forwards or backwards dominance. We can also consider a call to any `Never` returning function as a cold-exit, though the block(s) leading up to that call may be executed frequently because of concurrency. For now, I'm ignoring the concurrency case and assuming it's cold. To make use of this "no return" prediction, use the `-enable-noreturn-prediction` flag, which is currently off by default.

There's no reason to do further stages of analysis to propagate coldness if there wasn't any found in Stage 1.

I thought `reverse(silFn)` would do a post-order walk, but I was wrong. This patch cuts the number of iterations to propagate coldness from 3-4 down to 2 in a few of the simple regression test cases. At least on macOS (as the stdlib can vary per platform).

Latest compiler performance run looks much better. The 10% increase in instructions executed under the release build has been solved with the extra optimizations I've added:
