search for: tmpfresh

Hi! Is there a pass that will remove constant expressions from appearing within other expressions? For instance it would convert the call: %tmp20 = tail call i32 (i8*, ...)* @printf( i8* getelementptr ([4 x i8]* @.str, i32 0, i32 0), i32 %tmp18 ) ; <i32> [#uses=0] Into: %tmpFresh = getelementptr [4 x i8]* @.str, i32 0, i32 0 ; <i8*> [#uses = 1] %tmp20 = tail call i32 (i8*, ...)* @printf( i8* %tmpFresh, i32 %tmp18 ) ; <i32> [#uses=0] (Ideally it would do this as an .s -> .s transformation and be accessible through a tool like opt).
