Dan Gohman	df2896d609	Eliminate more uses of llvm-as and llvm-dis. ... llvm-svn: 81290	2009-09-08 23:54:48 +00:00
Eli Friedman	d7a261120f	Fix for PR2164: allow transforming arbitrary-width unsigned divides into ... multiplies. Some more cleverness would be nice, though. It would be nice if we could do this transformation on illegal types. Also, we would prefer a narrower constant when possible so that we can use a narrower multiply, which can be cheaper. llvm-svn: 60283	2008-11-30 06:02:26 +00:00
Dan Gohman	a9f8208852	Don't lower srem/urem X%C to X-X/C*C unless the division is actually ... optimized. This avoids creating illegal divisions when the combiner is running after legalize; this fixes PR1815. Also, it produces better code in the included testcase by avoiding the subtract and multiply when the division isn't optimized. llvm-svn: 44341	2007-11-26 23:46:11 +00:00
