[LLVMdev] RFC: change BoundsChecking.cpp to use address-based tests
...│ Cmp2: Size ≥ Offset
┆ ┆ Cmp3: ObjSize ≥ NeededSize
I am looking at generating IR like this:
%upperbound = getelementptr inbounds i64* %memobj, i64 %elements
%end = getelementptr inbounds i64* %ptr, i64 1
%ilowerbound = ptrtoint i64* %memobj to i64
%iupperbound = ptrtoint i64* %upperbound to i64
%iptr = ptrtoint i64* %ptr to i64
%iend = ptrtoint i64* %end to i64
%cmpl = icmp ult %iptr, %ilowerbound
%cmpu = icmp ult %iupperbound, %iend
%9 = or i1 %cmpl, %cmpu
br i1 %11, label %trap, label %12
