[LLVMdev] SCEV getMulExpr() not propagating Wrap flags
Hi folks,
I'm trying to analyse this piece of IR:
for.body: ; preds = %for.body,
%entry
%indvars.iv = phi i64 [ 0, %entry ], [ %indvars.iv.next, %for.body ]
%0 = shl nsw i64 %indvars.iv, 1
%arrayidx = getelementptr inbounds i32* %b, i64 %0
%1 = load i32* %arrayidx, align 4, !tbaa !1
%add = add nsw i32 %1, %I
%arrayidx3 = getelementptr
