Disallow implicit conversions between ilist iterators and element points. Explicit conversions still work of course. This is the first step toward removing the undefined behaviour in `ilist` and `iplist`: http://lists.llvm.org/pipermail/llvm-dev/2015-October/091115.html The motivation for removing the implicit iterators is that I came across real bugs (that were *really* getting lucky). More details and some brief discussion later in that thread: http://lists.llvm.org/pipermail/llvm-dev/2015-October/091617.html Note: if you have out-of-tree code, it should be fairly easy to revert this patch downstream while you update your out-of-tree call sites. Note that these conversions are occasionally latent bugs (that may happen to "work" now, but only because of getting lucky with UB; follow-ups will change your luck). When they are valid, I suggest using `->getIterator()` to go from pointer to iterator, and `&*` to go from iterator to pointer. llvm-svn: 252372 |
