Hi Alan,
the combined effect of
commit e3ec2e7ae94524ebd111963faf34b84d942265b4
WIP on combined Step 1 and 3 for Trees That Grow, HsExpr
and
commit 438dd1cbba13d35f3452b4dcef3f94ce9a216905
WIP on Doing a combined Step 1 and 3 for Trees That Grow
causes a 15% regression in the time it takes to build GHC, according to
https://perf.haskell.org/ghc/#compare/fe6848f544c2a14086bcef388c46f4070c22d287/e3ec2e7ae94524ebd111963faf34b84d942265b4
Is that a known, expected and accepted regression?
Joachim
