Chris Lattner 59723e9698 recognize some patterns as fabs operations, so that fabs at the source level ... is deconstructed then reconstructed here. This catches 19 fabs's in 177.mesa 9 in 168.wupwise, 5 in 171.swim, 3 in 172.mgrid, and 14 in 173.applu out of specfp2000. This allows the X86 code generator to make MUCH better code than before for each of these and saves one instr on ppc. This depends on the previous CFE patch to expose these correctly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21171 91177308-0d34-0410-b5e6-96231b3b80d8		2005-04-09 05:15:53 +00:00
