Re: x86 Darwin an libgcc-math
Awesome.
With trunk, your 3 previous patches, my config/darwin.h patch for the
link line, and your further patch for visibility:
[ssen@alias]$ /opt/gccmath/bin/gcc -o test test.c -msselibm
[ssen@alias]$ otool -Lv test
test:
/opt/gccmath/lib/libgcc-math.0.dylib (compatibility version
1.0.0, current version 1.0.0)
time stamp 1138831883 Wed Feb 1 14:11:23 2006
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0,
current version 88.1.5)
time stamp 1137810491 Fri Jan 20 18:28:11 2006
[ssen@alias]$ ./test
0.999816
Also, using nm I see that only the intentional support API is global.
[ssen@alias]$ nm -g -f /opt/gccmath/lib/libgcc-math.0.dylib | grep -v

Thank you very much! Bootstrapped on i386-apple-darwin8.4.1

Can you try the attached patch (it's not perfect as it misses to
export some
of the symbols due to the simple #define hack not working for them)
and
see if in principle it would solve the issue on Darwin?
Thanks,
Richard.
