Where is noexcept coming into play? Some std namespace function? mincore is marked noexcept on linux apparently, which is part of the reason I was getting build failures there.

Comment on attachment 426577 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=426577&action=review In a follow up patch I'll make sure we account for PreciseAllocations too. > Source/JavaScriptCore/heap/BlockDirectory.cpp:80 > + // FIXME: We could cache this in bulk (e.g. 25 MB chunks) but we haven't seen any data that it actually matters. Actually, this probably shouldn't be marked as a FIXME since we're not actually going to fix this until we say data saying it matters.
