#3655: Performance regression relative to 6.10
--------------------------------------+-------------------------------------
Reporter: simonmar | Owner:
Type: bug | Status: new
Priority: high | Milestone: 6.12.2
Component: Compiler | Version: 6.10.4
Resolution: | Keywords:
Difficulty: Unknown | Os: Unknown/Multiple
Testcase: | Architecture: Unknown/Multiple
Failure: Runtime performance bug |
--------------------------------------+-------------------------------------
Comment (by simonmar):
We tracked it down to `sequence_` not fusing with `map` in a couple of
places, due to `sequence_` not having arity 2 which was preventing a
partially-applied call being inlined, which meant that the rule didn't
fire. Simon PJ is going to investigate further.
