[Debuginfo] dbg.value points to undef value after Induction Variable Simplification.
Induction Variable Simplification pass does not update dbg.value intrinsic.
Before:
%add = add nuw nsw i32 %ArgIndex.06, 1
call void @llvm.dbg.value(metadata i32 %add, metadata !17, metadata !DIExpression())
After:
%indvars.iv.next = add nuw nsw i64 %indvars.iv, 1
call void @llvm.dbg.value(metadata i64 undef, metadata !17, metadata !DIExpression())
There should be:
%indvars.iv.next = add nuw nsw i64 %indvars.iv, 1
call void @llvm.dbg.value(metadata i64 %indvars.iv.next, metadata !17, metadata !DIExpression())
