Chris Lattner	c707fa9651	move some select simplifications out out instcombine into ... inst simplify. No functionality change. llvm-svn: 101873	2010-04-20 05:32:14 +00:00
Dan Gohman	cd4c03e886	Don't do (X != Y) ? X : Y -> X for floating-point values; it doesn't ... handle NaN properly. Do (X une Y) ? X : Y -> X if one of X and Y is not zero. llvm-svn: 96955	2010-02-23 17:17:57 +00:00
Duncan Sands	9dff9bec31	Uniformize the names of type predicates: rather than having isFloatTy and ... isInteger, we now have isFloatTy and isIntegerTy. Requested by Chris! llvm-svn: 96223	2010-02-15 16:12:20 +00:00
Chris Lattner	1b35bbe813	change the canonical form of "cond ? -1 : 0" to be ... "sext cond" instead of a select. This simplifies some instcombine code, matches the policy for zext (cond ? 1 : 0 -> zext), and allows us to generate better code for a testcase on ppc. llvm-svn: 94339	2010-01-24 00:09:49 +00:00
Benjamin Kramer	a81a6dff0d	Convert a ton of simple integer type equality tests to the new predicate. ... llvm-svn: 92760	2010-01-05 20:07:06 +00:00
Chris Lattner	1e7b7b50b1	clean up header. ... llvm-svn: 92688	2010-01-05 06:05:07 +00:00
Chris Lattner	8f771cb78f	split select out to its own file. ... llvm-svn: 92687	2010-01-05 06:03:12 +00:00
