History
Hans-Peter Nilsson 0e499e759c 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.
