Description octoploid 2015-03-03 07:53:02 UTC

Python upstream offers a "make profile-opt" target that automatically
first builds an instrumented version (with gcc's -fprofile-generate),
then runs some tests to train it and finally builds on optimized 
version with -fprofile-use.

Offering a use flag for this feature would be nice.
All recent gcc versions should work.

Reproducible: Always
