Instead of passing around a file descriptor
use a function pointer to facilitate more advanced
backend write logic such as size limitation or compression.

This is mostly a pure refactoring.
Except for the buggy cases when calling erlang:halt() with a positive
integer in the range -(INT_MIN+2) to -INT_MIN that got confused with
ERTS_ABORT_EXIT, ERTS_DUMP_EXIT and ERTS_INTR_EXIT.
Outcome OLD erl_exit(n, ) NEW erts_exit(n, )
------- ------------------- -------------------------------------------
exit(Status) n = -Status <= 0 n = Status >= 0
crashdump+abort n > 0, ignore n n = ERTS_ERROR_EXIT < 0
The outcome of the old ERTS_ABORT_EXIT, ERTS_INTR_EXIT and
ERTS_DUMP_EXIT are the same as before (even though their values have
changed).

This avoids potential integer arithmetic overflow for very large lists.

for naming style consistency.

which is same as old homeSize + splitPosition.

|
|
(homeSize + splitPosition) will do just fine

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.

by limiting table sizes to powers of 2.
This will change the default size from 10 to 8.

* egil/pd-opt-get/OTP-13167:
erts: Add i_get_hash instruction
erts: Use internal hash for process dictionaries
|
|
Calculate hashvalue in load-time for constant process dictionary gets.
|

* egil/process_dictionary-initial-size/OTP-12535:
erts: Document option 'hpds'
erts: Enable command line argument for initial pd size
|
|
Use '+hpds size' to set initial process dictionary size for spawned processes.
|
|
Returns a list of all keys in the process dictionary.

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.
