2017-08-11Break out most instructions from beam_emu.cBjörn Gustavsson
2017-08-08beam_makeops: Pretty-print the generated codeBjörn Gustavsson
2017-08-08beam_makeops: Define ARCH_32 and ARCH_64Björn Gustavsson
2017-08-08Introduce micro instructionsBjörn Gustavsson
beam_makeops will place all micro instructions in a block and generate goto instructions from one micro instruction to the next. It will also add adjustments of 'I' if necessary (if the micro instructions have different length).
2017-08-08Simplify specifying implementation of instructionsBjörn Gustavsson
Eliminate the need to write pre-processor macros for each instruction. Instead allow the implementation of instruction to be written in C directly in the .tab files. Rewrite all existing macros in this way and remove the %macro directive.

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.

2017-07-11erts: Fix bug in enif_whereis_pid/portSverker Eriksson
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.

erts: ensure alignment of VM core types
2017-07-10josevalim/jv-op-stacktrace-entry/PR-1478/OTP-14508Lukas Larsson
Add stacktrace entries to BIF calls from emulator
2017-07-10Add a dedicated close function for TCP ports to prevent issues like ERL-430/448John Högberg

2017-07-07Add a proper type for lock optionsJohn Högberg
2017-07-07Add stacktrace entries to BIF calls from emulatorJosé Valim
The goal of this change is to improve debugging of emulator calls. For example, the following code rem(1, y) will error with atom `badarith` when y is 0 and the stacktrace has no entry for `erlang:rem/2`, making such cases very hard to debug. This patch makes it so the stacktrace includes `erlang:rem(1, 0)`. The following emulator BIFs have been changed: * band/2 * bnot/1 * bor/2 * bsl/2 * bsr/2 * bxor/2 * div/2 * element/2 * int_div/2 * rem/2 * sminus/2 * splus/2 * stimes/2

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).

2017-07-06Introduce new_small_map_lit opMichal Muskala
Take advantage of the fact that small maps have a tuple for keys. When new map is constructed and all keys are literals, we can construct the entire keys tuple as a literal. This should reduce the memory of maps created with literal keys almost by half, since they all can share the same keys tuple.
