Chris Lattner 80e8b506b8 rewrite the memset_pattern pattern generation stuff to accept any 2/4/8/16-byte ... constant, including globals. This makes us generate much more "pretty" pattern globals as well because it doesn't break it down to an array of bytes all the time. This enables us to handle stores of relocatable globals. This kicks in about 48 times in 254.gap, giving us stuff like this: @.memset_pattern40 = internal constant [2 x %struct.TypHeader* (%struct.TypHeader*, %struct.TypHeader*)*] [%struct.TypHeader* (%struct.TypHeader*, %struct .TypHeader*)* @IsFalse, %struct.TypHeader* (%struct.TypHeader*, %struct.TypHeader*)* @IsFalse], align 16 ... call void @memset_pattern16(i8* %scevgep5859, i8* bitcast ([2 x %struct.TypHeader* (%struct.TypHeader*, %struct.TypHeader*)*]* @.memset_pattern40 to i8* ), i64 %tmp75) nounwind git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126044 91177308-0d34-0410-b5e6-96231b3b80d8		2011-02-19 19:56:44 +00:00
