Chris Lattner	1eeea0d262	add some more check for vector compares. ... llvm-svn: 75024	2009-07-08 18:51:25 +00:00
Chris Lattner	c153b998d9	eliminate the v[if]cmp versions of these tests, now that [if]cmp+sext works. ... llvm-svn: 74980	2009-07-08 00:49:35 +00:00
Chris Lattner	ea7bd9b484	dag combine sext(setcc) -> vsetcc before legalize. To make this safe, ... VSETCC must define all bits, which is different than it was documented to before. Since all targets that implement VSETCC already have this behavior, and we don't optimize based on this, just change the documentation. We now get nice code for vec_compare.ll llvm-svn: 74978	2009-07-08 00:31:33 +00:00
Chris Lattner	e2435c4f6f	add support for legalizing an icmp where the result is illegal (4xi1) but ... the input is legal (4 x i32) llvm-svn: 74964	2009-07-07 23:03:54 +00:00
Chris Lattner	1de1b3155b	add a trivial test that vector compares work. ... llvm-svn: 74963	2009-07-07 22:51:09 +00:00
