add fenv to libm
okay, this will have to be fixed not to contain types from freebsd. i am sure that you only need to modify files in lib/libm.
the port to amd64 has already started. however, it is not finished. it is crucial that all future work strictly respects this fact and integrates amd64.
for some reason we are now using netbsd's libm, and they don't have special treatment of amd64. i am pretty sure that is not needed in any case, it is merely an optimization.
to install a cpu-specific header, just add
Besides that, the freebsd code contains unnecessary compatibility code which should be removed (like splitting mxcsr).
#1 Updated by rumcic over 7 years ago
I got rid of the _types.h files and moved fenv.h to src/lib/libm/arch/i386/
The only changes in the source tree now are 2 new files (fenv.c and fenv.h)
and the modified Makefile.inc in lib/libm/arch/i386/.
