2012-02-21BEAM loader: Break out handling of ranges into beam_ranges.cBjörn Gustavsson
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.

2012-02-01beam_bp: Fix faulty assertion in erts_find_local_func()Björn Gustavsson
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.
2012-02-01beam_load: Fix faulty assertion in module_info(native_addresses)Björn Gustavsson
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.

2012-01-31erts: Correct incorrect assertion in erl_alloc_util.cBjörn Gustavsson
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).

2012-01-24beam_load.c: Allow stubs for BIFsBjörn Gustavsson
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.

2012-01-11beam_load.c: Don't show unnecessary context in errorsBjörn Gustavsson
For errors that occur after reading the code chunking, saying that the error occurred in the last function in the module and in the instruction int_code_end/0 is just confusing.
2012-01-11beam_load.c: Remove useless call to next_heap_size()Björn Gustavsson
The idea was probably to cause less fragmentation. Even if that would be true, it is irrelevant because the short-lived allocator that is used does not have any problems with fragmentation. In CodeNeed() we will simply double the size of the area used for code instead of using the next heap size.
2012-01-11beam_load.c: apply/2 does not need a special caseBjörn Gustavsson
It is wrongly assumed in the BEAM loader that apply/2 is a BIF and must be treated specially. Also make it clearer in ops.tab that apply/3 is a BIF, but apply/2 is not.

It is possible also in non-SMP case: 1. The process receives an exit signal and is set in status exiting and inserted into the run queue. 2. The distribution port exits before the process has been selected for execution and cannot remove the link half on the process since it is in status exiting. 3. Process is selected for execution and when removing this link half the distribution channel is gone!
