- Subject: let gmp-mparam.h choose the type of mp_limb_t
- Organization: GCC Team, Red Hat
mips64 n32 has 64-bit registers but has 32-bit longs. It felt
wasteful to not use 64-bit arithmetic, directly supported by the
hardware, in the glibc-internal gmp code, so I've arranged for
gmp-mparam.h, where it made the most sense to define the macros that
control the type of mp_limb_t, to be included wherever gmp.h was
included. Ok to install?
