OK. I've just updated both emacs-25 and master, and built them normally
(i.e. with default optimisation and no debugging info). The timings I
see (in seconds) are:
emacs-25 master
foo 2.62 2.78
bar 13.64 13.93
I honestly don't know why you're seeing a factor of 20 difference. I
doubt it's got anything to do with CC Mode. Perhaps you could tell me
what flags (e.g. CFLAGS) you're using in your non-optimised builds, and
I can rebuild and try again.
I also think that under 3 seconds is an acceptable running time for
`foo' and `bar'. (Yesterday's patch brings `bar''s running time down to
that of `foo')
