2016-01-08erts: Allow -fvisibility=hidden for NIFs and driversSverker Eriksson
as is strongly recommended by gcc man page. We use __attribute__ ((visibility("default"))) to make sure the init functions are properly exported.
2016-01-08erts: Cleanup erl_driver.h for windowsSverker Eriksson
The comment is misleading and no need to "export" static windows drivers. DRIVER_INIT for dynamic windows drivers is defined in erl_win_dyn_driver.h

2015-12-21Do not allow aux work on dirty schedulersSteve Vinoski
The nature of aux work is such that dirty schedulers should not attempt to perform it. Modify the code to ensure that dirty schedulers avoid aux work. Also fix an incorrect assumption about the size of a Uint in the ErtsDirtySchedId type.

* rickard/ohmq-fixup/OTP-13047: Fix check_process_code()
2015-12-15erts: Add 'fill_heap' to erts_debug:state_internal_stateSverker Eriksson
to make it easy to provoke GC inside/after a BIF or instruction.
2015-12-15erts: Rename proc dict size to arraySizeSverker Eriksson
for naming style consistency.
2015-12-15erts: Refactor proc dict with 'usedSlots'Sverker Eriksson
which is same as old homeSize + splitPosition.

2015-12-15erts: It is not possible to exit the forker driverLukas Larsson
2015-12-15erts: Fix memory leak at async open portLukas Larsson
When an async open port fails early, it would sometimes leak memory.
2015-12-15erts: Move os_pid to port hash to child setupLukas Larsson
Had to move the hashing because of a race that can otherwise happen where a new os_pid value was inserted into the hash before the previous value had been removed. Also replaced the protocol inbetween erts and child setup to be a binary protocol. This was done in order to deal with the varying size of Eterm.
2015-12-15erts: Fix forker driver ifdefs for win32Lukas Larsson
2015-12-15erts: Create forker process for spawn driverLukas Larsson
Instead of forking from the beam process, we create a separate process in which all forks are done. This has several advantages: 1) performance: * don't have to close all fd's in the world * fork only has to copy stuff from a small process * work is done in a completely seperate process * a 3x performance increase has been measured, can be made even greater (10x) if we cache the environment in child setup 2) stability * the exec is done in another process than beam, which means that if the file that we exec to is on an nfs that is not available right now we will not block a scheduler until the nfs returns. 3) simplicity * don't have to deal with SIGCHLD in the erts Unfortunately, this solution also implies some badness. 1) There will always be a seperate process running together with beam on unix. This could be confusing and undesirable. 2) We have to transfer the entire environment to child_setup for each command. OTP-13088

2015-12-09erts: Remove ProcDict.usedSverker Eriksson
(homeSize + splitPosition) will do just fine
2015-12-09erts: Add proc dict macros ERTS_PD_START/SIZESverker Eriksson
2015-12-09erts: Optimize away function "array_put" in proc dictSverker Eriksson
Replace heave array_put() with a dumb array index assignment ARRAY_PUT and instead introduce ensure_array_size() to be called when we know the array might need to grow. This change also ensures the entire HASH_RANGE is always allocated. No need for ARRAY_GET to check index any more.
2015-12-09erts: Optimize hashing in process dictionarySverker Eriksson
by limiting table sizes to powers of 2. This will change the default size from 10 to 8.
