Enormous FFI speedup observed

[Joachim Breitner]

Hi,

as I wrote on
http://www.joachim-breitner.de/blog/archives/546-GHC-7.4.1-speeds-up-arbtt-by-a-factor-of-22.html
I observe an enormous speed up (22×) in arbtt, and it seems to be
related to FFI function calls. The release notes do not give a hint what
has changed to result in this speed up, so I’m curious whether someone
here knows the reason, or can make a good guess?

Thanks,
Joachim
