2015-03-12erts: Change phash2 of maps to be sensitive to key-value combos.Sverker Eriksson

2014-02-27erts: Fix Map cmp exact equal of an empty mapBjörn-Egil Dahlberg
The expression, #{} =:= M where M was any Map, would always result in 'true'. This commit fixes this issue by first comparing sizes for both terms and then checking for size zero.

2014-02-24Added support for ENEA OSELukas Larsson
This port has support for both non-smp and smp. It contains a new way to do io checking in which erts_poll_wait receives the payload of the polled entity. This has implications for all linked-in drivers.
2014-02-19beam/utils.c: Change back cmp() to only take two argumentsBjörn Gustavsson
Commit d5c238473b9cec819d93faaef4ccc00ddb60465f added a third argument to the cmp() function, but did not change the code generation of native code that called cmp(). Name the new functions with an "erts_" prefix, and reinstate the old cmp() function with two arguments. We don't have to keep a cmp() function in the halfword emulator, since HiPE does not support the halfword emulator.
2014-01-29erts: Add cmp_term to compareBjörn-Egil Dahlberg
Uses total order of types meaning int < float
2014-01-28erts: erlang:phash2 should hash Maps independent of orderBjörn-Egil Dahlberg
2014-01-28erts: Add Maps to erlang:phash/2 and erlang:hash/2Björn-Egil Dahlberg
The hashing a map in these functions uses the same strategy as the other terms. The exception being a prime number with size so we do not get erlang:phash(#{}) -> 1 which would be the same as erlang:phash({}) and erlang:phash(<<>>). Same argument for erlang:hash/1.

2014-01-22erts: Fix crash when comparing very large floats with integersSverker Eriksson
big_buf was one word too short on 32-bit emulators causing memory corruption. Seems like this did not cause a problem before the ESTACK memory layout was changed in 172ebf11dc455e22b87f.
2014-01-22erts: Refactor big-float compare on HALFWORD to use C-stackSverker Eriksson
for the temporary conversion from float to big. Preparation for coming bugfix of 'big_buf' array size.
2014-01-17erts: Refactor ESTACK & WSTACK to use a struct easy to "export"Sverker Eriksson
This is not a clean refactor. It changes the behaviour slightly of E/WSTACK_RESTORE. The allocated stack from E/WSTACK_SAVE is used as-is and not copied into default_stack. This will hopefully fix an illusive memory leak that valgrind is reporting.

* rickard/garbage_collect/OTP-11388: Parallel check_process_code when code_server purge a module Functionality for disabling garbage collection Use asynchronous check_process_code in code_parallel_SUITE Execution of system tasks in context of another process Conflicts: bootstrap/lib/kernel/ebin/hipe_unified_loader.beam erts/preloaded/ebin/erlang.beam erts/preloaded/ebin/erts_internal.beam
2013-11-18Execution of system tasks in context of another processRickard Green
A process requesting a system task to be executed in the context of another process will be notified by a message when the task has executed. This message will be on the form: {RequestType, RequestId, Pid, Result}. A process requesting a system task to be executed can set priority on the system task. The requester typically set the same priority on the task as its own process priority, and by this avoiding priority inversion. A request for execution of a system task is made by calling the statically linked in NIF erts_internal:request_system_task(Pid, Prio, Request). This is an undocumented ERTS internal function that should remain so. It should *only* be called from BIF implementations. Currently defined system tasks are: * garbage_collect * check_process_code Further system tasks can and will be implemented in the future. The erlang:garbage_collect/[1,2] and erlang:check_process_code/[2,3] BIFs are now implemented using system tasks. Both the 'garbage_collect' and the 'check_process_code' operations perform or may perform garbage_collections. By doing these via the system task functionality all garbage collect operations in the system will be performed solely in the context of the process being garbage collected. This makes it possible to later implement functionality for disabling garbage collection of a process over context switches. Newly introduced BIFs: * erlang:garbage_collect/2 - The new second argument is an option list. Introduced option: * {async, RequestId} - making it possible for users to issue asynchronous garbage collect requests. * erlang:check_process_code/3 - The new third argument is an option list. Introduced options: * {async, RequestId} - making it possible for users to issue asynchronous check process code requests. * {allow_gc, boolean()} - making it possible to issue requests that aren't allowed to garbage collect (operation will abort if gc should be needed). These options have been introduced as a preparation for parallelization of check_process_code operations when the code_server is about to purge a module.
