Chris Lattner	d842962e27	change selectiondag to add the sign extended versions of immediate operands ... to instructions instead of zero extended ones. This makes the asmprinter print signed values more consistently. This apparently only really affects the X86 backend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81265 91177308-0d34-0410-b5e6-96231b3b80d8	2009-09-08 23:05:44 +00:00
Eli Friedman	201c9776bd	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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60283 91177308-0d34-0410-b5e6-96231b3b80d8	2008-11-30 06:02:26 +00:00
