The macro HIPE_SYSTEM_CRC used to contain a hidden cookie from the VM
that generated hipe_literals.hrl. This means that BEAM files containing
that macro would be tied to a particular version of the VM.
Change hipe_bifs:system_crc such that it doesn't require a hidden cookie
to return the desired value.

Dirty schedulers are limited in the type of work they can
perform. Make sure they do not participate in any work or make any
function calls related to timer wheels.
|
|
Also fix and document the broken +We option.

Previously, the emulator would generate a whole string
with values and call the error_logger passing "~s~n".
This commit changes it to a format string containing ~p
with the respective values as arguments.
|
|
This function allows us to send format and args to the
logger which can then be formatted and customized from
Erlang land.

There is no need to take special care of Maps at all since header_arity(hdr)
will take care of the normal case via its Map handling.
|
|
The optimization cannot be used due to that the pattern cannot be ordered.

The current size is too small for 64-bit machines,
causing messages to be truncated and making debugging
more difficult.

sys_write_buf allocator type is used from async-threads and needs
to be lockable. In the SMP case the temporary allocator is lockable but
not in the Non-SMP case.
To remedy this the binary-allocator is used for the Non-SMP case,
which is lockable.

The Android support in erl_child_setup.c is broken:
1. The close fd loop compares an fd (integer i) with the address of the function
__system_properties_fd rather than the value of calling that function.
2. This function is locally defined, but its name starts with two underscores
which is reserved for the implementation.
3. This function is not used outside of this file, so should be static.
4. This function performs a fair amount of work (calls getenv and atoi), which
would be repeated for each and every fd in the [from,to] range.
5. This function contains an unsed local variable 's'.
Fixed by dropping the __ prefix, making the function static, dropping the unused
local variable, and rewriting the close fd loop to call the function at most once.
