2017-07-12erts: Fix bug in bxor of a big negative numberSverker Eriksson
Wrong result for (X bsl WS) bxor Y. where X is any negative integer Y is any integer that does not require more words than X WS is erlang:system_info(wordsize) or larger Fix: The subtraction of 1 (for 2-complement conversion) must be carried along all the way to the last words.

that could cause heap corruption if whereis lookup conflicts with other register updater AND other thread sends on-heap message while main lock is released. Also improved enif_whereis from dirty nifs by passing c_p as NULL.

2017-07-06Allow toggling lock counting at runtimeJohn Högberg
The implementation is still hidden behind ERTS_ENABLE_LOCK_COUNT, and all categories are still enabled by default, but the actual counting can be toggled at will. OTP-13170
2017-07-06Move lock flags to a common headerJohn Högberg
2017-07-06Enable register_SUITE for lcnt buildsJohn Högberg
It was disabled for performance reasons, and the new implementation handles it just fine (roughly half as fast as without lcnt).

2017-07-04macOS: Fix problems loading cryptoBjörn Gustavsson
On macOS, it was not possible to start crypto after running observer. (ERL_251) On the beta of macOS 10.13 (High Sierra), crypto does not work at all. (ERL-439) The problem is that the use of the -flat_namespace option when linking dynamic drivers such as the one for crypto. With that option, all function names must be unique among all linked libraries and frameworks, or the wrong function could be called. Resolve the problem by using the two-level namespace as recommended by Apple. We need to use the -bundle_loader option to point out beam.smp when building all drivers and NIF libraries. https://bugs.erlang.org/browse/ERL-251 https://bugs.erlang.org/browse/ERL-439

Choose a "lagom" low value to provoke both fallback on erts_alloc AND thread racing in lockless deallocation queue.

2017-06-30erts: Fix bug in quick allocSverker Eriksson
The effect of the race is that a pre-allocated memory block is inserted last without updating tail.data.last, which will cause all subsequent insertions to also fail to update tail.data.last. Hence all pre-allocation for this quick alloc instance is leaked for this thread and will fallback on erts_alloc.

2017-06-26Eliminate potential unsafe use of general destinationBjörn Gustavsson
a3407eaa2104d6 eliminated the -gen_dest flag for macros in ops.tab. It turns out that the new implementation (taking the address of the X or X destination register) is unsafe if the destination is a Y register and there can be a GC. The problem is that the address to the Y register will change if there is a GC. Fortunately, the few instructions in OTP 20 that have a general destinations are safe. The put_list_ssd instruction never does a GC. The bit syntax instructions that may do a GC will always store the result to an X register. To be completely sure, rewrite the destination register from 'd' to 'x' for the bit syntax instructions. That means that a bit syntax instruction with a Y register destionation will abort the loading if it is encountered.
