An incoming suspend monitor down wasn't handled correct when the local monitor half had been removed with an emulator crash as result.
2018-08-17Teach binary instructions to use Y registers as destinationBjörn Gustavsson
The new code generator will use Y registers as a destination for binary construction and matching instructions. v3_codegen would always first store terms in an X register and it would be the responsibility of the optimization passes to optimize the extra moves.

2018-08-16Do not allocate good and bad shifts for single byte lookupsJosé Valim
The single byte lookups always rely on `memchr` and never really use the good and bad shifts arrays.

2018-08-07Optimize binary matchJosé Valim
The idea is to use memchr on the first lookup for binary:match/2 and also after every match on binary:matches/2. We only use memchr in case of matches because benchmarks showed that using memchr even when we had false positives could negatively affect performance. This speeds up binary matching and binary splitting by 4x in some cases and by 70x in other scenarios (when the last character in the needle does not occur in the subject). The reason to use memchr is that it is highly specialized in most modern operating systems, often defaulting to SIMD operations. The implementation uses the reduction count to figure out how many bytes should be read with memchr. We could increase those numbers but they do not seem to make a large difference.

2018-08-03erts: Fix seq_trace to not clear token for system messagesLukas Larsson
A lot of erts internal messages used behind APIs to create non-blocking calls, e.g. port_command, would cause the seq_trace token to be cleared from the caller when it should not. This commit fixes that and adds asserts that makes sure that all messages sent have to correct token set. Fixes: ERL-602
