Chris Lattner 5d461d20ae Implement a fixme. The helps loops that have induction variables of different ... types in them. Instead of creating an induction variable for all types, it creates a single induction variable and casts to the other sizes. This generates this code: no_exit: ; preds = %entry, %no_exit %indvar = phi uint [ %indvar.next, %no_exit ], [ 0, %entry ] ; <uint> [#uses=4] *** %j.0.0 = cast uint %indvar to short ; <short> [#uses=1] %indvar = cast uint %indvar to int ; <int> [#uses=1] %tmp.7 = getelementptr short* %P, uint %indvar ; <short*> [#uses=1] store short %j.0.0, short* %tmp.7 %inc.0 = add int %indvar, 1 ; <int> [#uses=2] %tmp.2 = setlt int %inc.0, %N ; <bool> [#uses=1] %indvar.next = add uint %indvar, 1 ; <uint> [#uses=1] br bool %tmp.2, label %no_exit, label %loopexit instead of: no_exit: ; preds = %entry, %no_exit %indvar = phi ushort [ %indvar.next, %no_exit ], [ 0, %entry ] ; <ushort> [#uses=2] *** %indvar = phi uint [ %indvar.next, %no_exit ], [ 0, %entry ] ; <uint> [#uses=3] %indvar = cast uint %indvar to int ; <int> [#uses=1] %indvar = cast ushort %indvar to short ; <short> [#uses=1] %tmp.7 = getelementptr short* %P, uint %indvar ; <short*> [#uses=1] store short %indvar, short* %tmp.7 %inc.0 = add int %indvar, 1 ; <int> [#uses=2] %tmp.2 = setlt int %inc.0, %N ; <bool> [#uses=1] %indvar.next = add uint %indvar, 1 *** %indvar.next = add ushort %indvar, 1 br bool %tmp.2, label %no_exit, label %loopexit This is an improvement in register pressure, but probably doesn't happen that often. The more important fix will be to get rid of the redundant add. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13101 91177308-0d34-0410-b5e6-96231b3b80d8		2004-04-21 22:22:01 +00:00
