This issue actually affects the Safari in the latest OSX. We confirmed with our users that this is a regression introduced between `Safari 11.0.3 (13604.5.6)` and `Safari 11.1 (13605.1.33.1.2)`.

Seems like a real bug in NaturalLoops.

Comment 14 2018-06-10 18:55:25 PDT
(In reply to Saam Barati from comment #13) > Seems like a real bug in NaturalLoops. I think this is the bug: NaturalLoops's algorithm breaks down if a loop contains the same block more than once. This can happen in a case like this: block:header something something switch (case 1: header, case 2:header, etc)

This can happen in a case like this: > > block:header > something > something > switch (case 1: header, case 2:header, etc) I still don't know why exactly the algorithm breaks down, but it makes this loop produce wrong things inside the m_innerMostLoopIndices map: ``` for (unsigned loopIndex = m_loops.size(); loopIndex--;) { NaturalLoop<Graph>& loop = m_loops[loopIndex]; for (unsigned blockIndexInLoop = loop.size(); blockIndexInLoop--;) { typename Graph::Node block = loop[blockIndexInLoop]; for (unsigned i = 0; i < std::tuple_size<InnerMostLoopIndices>::value; ++i) { unsigned thisIndex = m_innerMostLoopIndices[block][i]; if (thisIndex == UINT_MAX || loop.size() < m_loops[thisIndex].size()) { insertIntoBoundedVector( m_innerMostLoopIndices[block], std::tuple_size<InnerMostLoopIndices>::value, loopIndex, i); break; } } } } ``` I need to figure out why
Saam Barati
Comment 16 2018-06-10 18:58:58 PDT
Seems mostly obvious why, actually. It'll do things for a block more than once now. That could make it compute things more than once in a way the algorithm isn't expecting for the same loop.
