2011-11-26beam_load.c: Add init_iff_file() for verifying the IFF headerBjörn Gustavsson
Add init_iff_file() for verifying the IFF header. Also let it handle compressed BEAM files so that it will be done in one place. That means that code:get_chunk/2 and code:module_md5/1 will now support compressed BEAM files.

2011-11-26beam_load.c: Optimize code:get_chunk/2Björn Gustavsson
The undocumented code:get_chunk/2 BIF is supposed to be a fast way to extract a chunk from a BEAM file when loading native code. In practice, it might not have been faster because it happened to calculate an MD5 checksum for the chunk it extracted because it shared the scan_iff_file() function with the erlang:load_module/2 BIF. Split scan_iff_file() into scan_iff_file() and verify_chunks(), so that the unnecessary MD5 calculation can be avoided.
2011-11-26beam_load.c: Eliminate memory leak in code:make_stub_module/3Björn Gustavsson
code:make_stub_module/3 leaked memory if given either a corrupt BEAM file, or a compressed BEAM file and an error occurred, or a binary not aligned on byte boundaries.
2011-11-25Fix clang linking problemBjörn Gustavsson
Inlining was not done in a portable way. clang follows the C99 semantics for inlining ('inline' essentially implies 'static' in C99, but not in GCC), so bp_sched2ix() was not visible outside beam_bp.c. Since the function need to be used from more than one source file, put the function definition in the beam_bp.h header file. Also, give it an 'erts_' prefix since it is globally visible.

2011-11-18Use unbound schedulers as defaultRickard Green
As of ERTS version 5.9 (OTP-R15B) the runtime system will by default not bind schedulers to logical processors. If the Erlang runtime system is the only operating system process that binds threads to logical processors, this improves the performance of the runtime system. However, if other operating system processes (as for example another Erlang runtime system) also bind threads to logical processors, there might be a performance penalty instead. In some cases this performance penalty might be severe. Due to this, we change the default so that the user must make an active decision in order to bind schedulers.

2011-11-17external.c: Remove the option to create over-sized heap binariesBjörn Gustavsson
Since refc binaries are now supported in literal pools, there is no longer any need to allow the creation of over-sized heap binaries.
2011-11-17Allow refc binaries in literal poolsBjörn Gustavsson
To simplify the implementation of literal pools (constant pools) for the R12 release, a shortcut was taken regarding binaries -- all binaries would be stored as heap binaries regardless of size. To allow a module containing literals to be unloaded, literal terms are copied when sent to another process. That means that huge literal binaries will also be copied if they are sent to another process, which could be surprising. Another problem is that the arity field in the header for the heap object may not be wide enough to handle big binaries. Therefore, bite the bullet and allow refc binaries to be stored in literal pools. In short, the following need to be changed: * Each loaded module needs a MSO list, linking all refc binaries in the literal pool. * When check_process_code/2 copies literals to a process heap, it must link each referenced binary into the MSO list for the process and increment the reference counter for the binary. * purge_module/1 must decrement the reference counter for each refc binary in the literal pool.

2011-11-17BEAM loader: Don't stop other schedulers until truly neededBjörn Gustavsson
The erlang:module_load/2 BIF will stop all other schedulers before it starts to process the BEAM file. That is not a problem when starting the Erlang/OTP system, since the start-up is mostly sequential. It is a problem, however, when big BEAM files are loaded in an already running system. After the refactoring in the previous commits, we can now do most of the processing of the BEAM file before we stop the other schedulers, so that we can minimize the time when only one scheduler will be running.

2011-11-14BEAM loader: Refactor code loading into separate functionsBjörn Gustavsson
Break apart code loading into the three functions: erts_alloc_loader_state() erts_prepare_loading() erts_finish_loading() The erts_alloc_loader_state() and erts_prepare_loading() can be executed with all schedulers running. Only erts_finish_loading() needs to be run in a single-scheduling system.

2011-11-14BEAM loader: Clean up handling of error reasonsBjörn Gustavsson
There is no reason to have erts_load_module() return integer values, only to have the caller convert the values to atoms. Return the appropriate atom directly from the place where the error is generated instead. Return NIL if the module was successfully loaded.
