Hi Luke, I've noticed that a new WARN in OccurAnal seems to be quite loud. Validations now produce thousands of lines of the form,
WARNING: file compiler/simplCore/OccurAnal.hs, line 2633
OccurAnal failed to rediscover join point(s): [$j_shTG]
WARNING: file compiler/simplCore/OccurAnal.hs, line 2633
OccurAnal failed to rediscover join point(s): [$w$j_sl22]
WARNING: file compiler/simplCore/OccurAnal.hs, line 2633
OccurAnal failed to rediscover join point(s): [$w$j_sl1W]
WARNING: file compiler/simplCore/OccurAnal.hs, line 2633
OccurAnal failed to rediscover join point(s): [$w$j_sl1Q]
Do you think we could either quiet the warning down a bit or perhaps
disable it by default? It makes it rather difficult to see through the
noise.
This is actually perhaps another case where Simon Marlow suggestion of
introducing a family of -v* flags (e.g. -fvanishing-join-points) might
be helpful.
Cheers,
- Ben
