Literal tags are used by the VM as an alternative to reserving a large
virtual memory space in order to be able to quickly identify which terms
are literals. The use of literal tags harms performance, but is useful
to support systems where allocating a large amount of virtual memory is
not an option.

Since gcunsafe values are live over is_divisible calls (although only
the happy path, which never GCd), it should be a primop so there cannot
be any GCs.

Fix hipe bug in binary <<X/utf32>> construction
|
|
by introducing new primop 'is_unicode'
with no exception (ab)use and no GC.
Replaces bs_validate_unicode which is kept for backward compat for now.
|
|
Fix for x86_64 only.
The calling native code can not handle a GC
as it has a raw pointer where to write the binary data.
If a GC happens the data (utf32) will be written
to the old deallocated heap.

Native code does not register its literals in the code header for the
loaded code. Therefore, a literal created by native code can not be
found by mark_literal(). Ignore literals that can't be found instead
of crashing (the crasdump_viewer will report such literals as
incomplete heap data, but will not crash).

erlang:is_builtin(erlang, M, F) returns false for apply/2 and
yield/0. The documentation for erlang:is_builtin/3 says that it
returns true for BIFs that are implemented in C. apply/2 and
yield/0 are implemented in C (as BEAM instructions), and
therefore the correct return value is true.
Also see a similar argument that was made for apply/3 in the past:

gen_sctp:connect_init/4 could return error even though the connect are in progress.
I.e. connect on socket returned "in progress".
The error can come from packet_inet_output() which is checking the socket for errors.
The issue here is that from erlang you don't think the connect is still ongoing.
But you will receive a sctp_assoc_change message later on.

* lukas/erts/fix-cpu-bind-w-modifies-scheduler-avail/OTP-14694:
erts: Fix so that bind correct schedulers
|
|
When the cpu ids and scheduler ids don't match,
the end schedulers could end up not being bound
when they should be.
example:
> taskset -c 1-3 erl +S 4 +sbts
> erlang:system_info(scheduler_bindings).
{1,2,3,unbound}
This fix makes it so that all cores are used to
bind schedulers.

Optimize instructions for comparing a register with a literal

We can avoid calling eq() from the is_eq_exact_literal/3
and is_ne_exact_literal/3 instructions if the source operand is
an immediate (since a literal is either a boxed or a list, never
an immediate).

When a literal was used from several processes, the literal would
be dumped in only one of the processes. The other processes
that referenced the literals would have incomplete heap data.
|
|
Maps would be dumped as the atom 'undefined', which is
not very informative.
|
|
Writing of crash dumps were done using unbuffered IO. This
is slow since many small writes are done.
Use a FILE* with an allocated buffer to obtain buffered IO.
I wrote a small test program that created 50000 binaries of 200 bytes
each and then created a crash dump. The crash dumping was an order of
magnitude faster with buffered IO than without.
