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. llvm-svn: 81265 2009-09-09 01:05:44 +02:00			`; RUN: llc < %s -mtriple=i686-pc-linux-gnu \| grep -- -1985`
Followup to r60283: optimize arbitrary width signed divisions as well as unsigned divisions. Same caveats as before. llvm-svn: 60284 2008-11-30 07:35:39 +01:00			`target datalayout = "e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:32:64-f32:32:32-f64:32:64-v64:64:64-v128:128:128-a0:0:64-f80:32:32"`
