Hi all,
I just committed the new mingw/mingwex/mathce dir, which contains the
c99 math extensions
to coredll. This code is mostly based on the libm from OpenBSD, which
is mostly based
on code copyrighted to Sun with the following license:
/*

*/
A few files are BSD (The Regents version) licensed.

I ported and ran the newlib/libm/test testsuite to mingw32ce, MinGW and
Cygwin.
The failures I get on mingw32ce are very similar to the ones I get on
desktop MinGW,
which suggests that there isn't much we can do without overriding the
native math functions
from coredll.dll. Surprisingly on Cygwin (which is newlib based) I get
a lot of failures too. Plus,
I see some suspiciously-looking-like-broken-test things on that
testsuite, so I am not committing it
for the moment. I've taken a few seconds look into glibc math
testsuite, and I think it would be
nice to run it over mingw32ce and MinGW. Maybe someone wants to take a
stab at it?
A few notes:
- This is purely a software based implementation - no FPU (VFP, FPA)
is used. Think slooow.
Volunteers welcome.
- Some functions are missing (particularly the long long versions)
- Don't be surprised if you see any mathematical aberration. My
math programming mojo is not
too far from nil.
Cheers,
Pedro Alves
