[pypy-dev] Re: Very long compilation on pypy

Hello,

If you are using a recent gcc version (>= 3.3 or 3.4) you could try to
use : -O2 -fno-unit-at-a-time
Here's a sample of the documentation :
"""Parse the whole compilation unit before starting to produce code.
This allows some extra optimizations to take place but consumes more
memory (in general)."""
I haven't tried it (doing it right now) but it should improve things.

regards,
