For CRIS ports, switch to soft-fp. Improve arit.c and longlong.h.
* config.host (cpu_type) <Setting default>: Add entry for
crisv32-*-*.
(tmake_file) <crisv32-*-elf, cris-*-elf, cris-*-linux*>
<crisv32-*-linux*>: Adjust.
* longlong.h: Wrap the whole CRIS section in a single
defined(__CRIS__) conditional. Add comment about add_ssaaaa
and sub_ddmmss.
(COUNT_LEADING_ZEROS_0): Define when count_leading_zeros is
defined.
[__CRIS__] (__umulsidi3): Define.
[__CRIS__] (umul_ppmm): Define in terms of __umulsidi3.
* config/cris/sfp-machine.h: New file.
* config/cris/umulsidi3.S: New file.
* config/cris/t-elfmulti (LIB2ADD_ST): Add umulsidi3.S.
* config/cris/arit.c (SIGNMULT): New macro.
(__Div, __Mod): Use SIGNMULT instead of naked multiplication.
* config/cris/mulsi3.S: Tweak to avoid redundant register-copying;
saving 3 out of originally 33 cycles from the fastest
path, 3 out of 54 from the medium path and one from the longest
path. Improve comments.
