The TMPBUF option is no longer needed due to is_literal test and NONE
was only used for initial debugging. So we remove the entire option.

Repeatedly reload a literals module while sending
the references literals around in a process ring.
This will smoke test the non-copying literals message sending does
not corrupt code unloading.

The Map implementation has changed since initial preserved copy implementation.
|
|
Halfword is no longer present in the runtime system.
|
|
The internal stacks has changed between releases.

This is very verbose, you have been warned.
It should work with the copy-spy.py script, which may be a bit outdated.

This commit is just for debugging purposes, will probably be reverted.
It comes with a the erts_debug:copy_shared/1 BIF. If SHCOPY_DISABLE
is defined, SHCOPY starts disabled and is dynamically enabled the first
time that the BIF is called.

Add functions size_shared, copy_shared_calculate and copy_shared_perform.
Add the infrastructure for making these communicate with each other.
Add debug information to other places in the VM, to watch interaction
with the sharing-preserving copy.
CAUTION: If you define the SHCOPY_DEBUG macro (after SHCOPY is actually
used in the VM) and make the whole OTP, there will be a lot of debugging
messages during make (it will also be enabled in erlc). You have been
warned...

Before 912fea0b beam_validator could validate disassembled files.
That's probably why the entry label was allowed to be 'undefined'.

No one has used the debug support in many years. Also, the debug
support is not free. There are calls to lists:foreach/2 that will be
executed even when debug support is turned off.

Avoid yield in the BIF when input is small. This either yielding
before beginning to work in the BIF, or by allowing some more
reductions before yielding.
