Introduce two new BIFs, erlang:prepare_loading/2 and
erlang:finish_loading/1, and re-implement erlang:load_module/2 in
Erlang code.
We have two reasons for doing this:
* To facilitate suspending a process if another process
is already doing code loading.
* In the future, we can implement parallel and atomic loading
of several modules. Atomic loading works except for modules with
on_load handlers. Because of that issue, erlang:finish_loading/2
will currently only accept a list with a single magic binary.

Update preloaded erlang.beam
Removed stray error in dialyzer test suite - different error message
with the new specs.
|
|
This involves exception BIF's, guar BIF's and some other complicated BIF's
Also some minor corrections to documentation and specs in erlang.erl
Added comment for each spec in erlang.erl shadowed by erl_bif_types.
Dialyzer test should now run well except for one or two cases.
|
|
New errors found when adding specs to erlang.erl and
removing them from erl_bif_types are examined and corrected.
Some errors was due to faulty specs, while others were actual
errors in the code using BIF's.
|
|
Reintroduced setelement in erlang.erl and erlang.xml
Preloaded erlang.beam updated.

aa_mem_data/2 is only called by aa_mem_data/1 and itself.
aa_mem_data/1 called with the argument 'notsup' will never
call aa_mem_data/2. aa_mem_data/2 will only call itself with
a #memory{} record as the first argument. QED.
Noticed-by: Dialyzer.

A number of memory allocation optimizations have been implemented. Most
optimizations reduce contention caused by synchronization between
threads during allocation and deallocation of memory. Most notably:
* Synchronization of memory management in scheduler specific allocator
instances has been rewritten to use lock-free synchronization.
* Synchronization of memory management in scheduler specific
pre-allocators has been rewritten to use lock-free synchronization.
* The 'mseg_alloc' memory segment allocator now use scheduler specific
instances instead of one instance. Apart from reducing contention
this also ensures that memory allocators always create memory
segments on the local NUMA node on a NUMA system.

concat_binary/1 was deprecated in R13B04, but already in
the R10B-2 release, the documentation recommends using
list_to_binary/1 instead.
|
|
An incorrect spec, rpc:yield/1, has been fixed.

Import directives still not sorted out!
