Chris Lattner a1246ba8ed Teach argpromote to ruthlessly hack small byval structs when it can ... get away with it, which exposes opportunities to eliminate the memory objects entirely. For example, we now compile byval.ll to: define internal void @f1(i32 %b.0, i64 %b.1) { entry: %tmp2 = add i32 %b.0, 1 ; <i32> [#uses=0] ret void } define i32 @main() nounwind { entry: call void @f1( i32 1, i64 2 ) ret i32 0 } This seems like it would trigger a lot for code that passes around small structs (e.g. SDOperand's or _Complex)... llvm-svn: 45886		2008-01-11 22:31:41 +00:00
