Move implementation from beam_load into new file code_ix.c and module.c
and make some function inline.

|
The is a refactoring in preparation to add a counter in Module struct
for export entry tracing. It is nicer if the two are kept together.
|
|
|
|
|
|
Staging is a better and more general name as does not necessary need
to involve code loading (can be deletion, tracing, etc).
|
|
Easy fallback solution that goes single threaded if the module to be
purged has a loaded nif lib.
|
|
|
|
Same as index_put() but returns pointer to entry instead of index integer.
|
|
Use a more general approach that does not assume in which order
the table entries in a blob are allocated and freed.
|
|
|
|
|
|
As it can only be used at initialization for preloading
|
|
Renamed merge_secondary_table and called by export_start_load
|
|
Implemented some code_ix locks
and commented calls to erts_smp_thr_progress_block()
|
|
|
|
Having the entire implementation of range handling (address table)
in one source file will help when we'll need to update the ranges
without stopping all schedulers in the next commit.

The default array was defined but not used.

Commit 64ccd8c9b7a782ca777ca4649dbb1f4a1ef00bce introduced BIF
stubs. The stub functions were not actually remove the loaded
code, but the name of the function in the func_info instruction
was changed to [] to mark it as invalid.

Commit 64ccd8c9b7a782ca777ca4649dbb1f4a1ef00bce introduced BIF
stubs. The stub functions were not actually remove the loaded
code, but the name of the function in the func_info instruction
was changed to [] to mark it as invalid.
The actual code for module_info(native_addresses) did not need
to be updated (a BIF stub can never have a native address and
a function without a native address will never be included in
the list), but the assertion that the name is an atom is no
no longer correct.

erts: Correct incorrect assertion in erl_alloc_util.c
|
|
The incorrect assertion would fire when '+Muramv true' has been
given, i.e. when a reallocation always forces a move.
Change the assertion to not call the lock checker if the mutex is
not used (because the allocator will only be accessed from a
specific scheduler and thus no lock is needed).

beam_load.c: Allow stubs for BIFs

We want to be able to write type specifications for BIFs in the same
way as for any other function. Currently, the type for BIFs need
to be described in erl_bif_types.
To avoid extending the compiler and Dialyzer with special directives
for providing specifications for BIFs, we have decided to let the
loader accept a local definition for a function which exists as a
BIF. As an example, here is how a stub for lists:reverse/2 can be
defined:
-export([reverse/2]).
-spec reverse([term()], term()) -> [term()].
reverse(_, _) ->
erlang:nif_error(undef).
Essentially, the loader will discard the local definition of reverse/2.
Other functions in the same module must *not* do local calls to a BIF
stub. If a local call to a BIF is found, the loader will refuse to load
the module. That is, the following call is not allowed:
reverse(List) ->
reverse(List, []).
but the following is:
reverse(List) ->
?MODULE:reverse(List, []).
A few words about the implementation.
It turns out to be too complicated to actually discard the BIF
stubs. Although it would be possibly with some jiggery pokery in
ops.tab, the code would be difficult to maintain and it could slow
down loading of modules that don't define BIFs (which are almost
all modules).
Therefore, the stub functions are kept in the loaded code, but
their names in the func_info instruction are invalidated so that
module_info(functions) can filter them out.
