Browse Source 
* i386.c (ix86_expand_movstr, ix86_expand_clrstr): Consistently
	do libcall for large blocks.
	* i386.md (comi patterns): Set type to ssecomi.
	(sse2_unpck?pd): Fix mode of vec_select.

	* cse.c: Include except.h
	(cse_set_around_loop):  Do not create new basic blocks.
	* Makefile.in (cse.o): Add dependnecy on except.h
