to include upgrade from deleted (old) module instance
|
|
Normally, calling code:delete/1 before re-loading the code for a
module is unnecessary but causes no problem.
But there will be be problems if the new code has an on_load function.
Code with an on_load function will always be loaded as old code
to allowed it to be easily purged if the on_load function would fail.
If the on_load function succeeds, the old and current code will be
swapped.
So in the scenario where code:delete/1 has been called explicitly,
there is old code but no current code. Loading code with an
on_load function will cause the reference to the old code to be
overwritten. That will at best cause a memory leak, and at worst
an emulator crash (especially if NIFs are involved).
To avoid that situation, we will put the code with the on_load
function in a special, third slot in Module.

Thread progress leader update did not cache current unmanaged index
when waiting for unmanaged threads. This caused
erts_thr_progress_unmanaged_delay() to stop working until a new leader
took over.

|
|
Add math:floor/1 and math:ceil/1 to avoid unnecessary conversions
in floating point expressions. That is, instead of having to write
float(floor(X)) as part of a floating point expressions, we can
write simply math:floor(X).
|
|
Implement as ceil/1 and floor/1 as new guard BIFs (essentially part of
Erlang language). They are guard BIFs because trunc/1 is a guard
BIF. It would be strange to have trunc/1 as a part of the language, but
not ceil/1 and floor/1.

When running the signal handler, the errno has to be restored
to its original value, otherwise code running in the same thread
may misbehave.

clang will generate smaller code if we avoid reassigning the
reg and freg arrays. That can be easily arranged by passing them
as arguments to process_main().
|
|
sys_pre_expand previously did a lot more work, for example,
translating records and funs, but now is merely a grab bag
of small transformations. Move those transformations to
v3_core.
