2014-06-05Replace erlang:binary_to_term() Erlang wrappersRickard Green
Replace the 'erlang:binary_to_term/1' and 'erlang:binary_to_term/2' Erlang wrappers taking care of failure after yield with management of this in the hidden yield BIF.

2014-03-07Add a BIF that only returns the atom okYiannis Tsiouris
A call in llvm_fix_pinned_regs/0 is inserted in the beginning of LLVM unwind blocks (i.e. code executed when an LLVM 'invoke' call triggers an exception) in order to get the BP and SP registers right. This is needed because LLVM exception handling doesn't provide the return value (that also contains the values for these registers, as defined in the HiPE Calling Convention for LLVM) on the 'landingpad's.

2014-02-28hipe: Break apart hipe_bif:make_fe/3 into two BIFsBjörn Gustavsson
This commit is a preparation for eliminating a race condition loading the native code for modules whose BEAM code has already been loaded. Here we introduce two new BIFs so that looking up a fun entry is separate from setting the native address in the fun entry.

2013-11-18Execution of system tasks in context of another processRickard Green
A process requesting a system task to be executed in the context of another process will be notified by a message when the task has executed. This message will be on the form: {RequestType, RequestId, Pid, Result}. A process requesting a system task to be executed can set priority on the system task. The requester typically set the same priority on the task as its own process priority, and by this avoiding priority inversion. A request for execution of a system task is made by calling the statically linked in NIF erts_internal:request_system_task(Pid, Prio, Request). This is an undocumented ERTS internal function that should remain so. It should *only* be called from BIF implementations. Currently defined system tasks are: * garbage_collect * check_process_code Further system tasks can and will be implemented in the future. The erlang:garbage_collect/[1,2] and erlang:check_process_code/[2,3] BIFs are now implemented using system tasks. Both the 'garbage_collect' and the 'check_process_code' operations perform or may perform garbage_collections. By doing these via the system task functionality all garbage collect operations in the system will be performed solely in the context of the process being garbage collected. This makes it possible to later implement functionality for disabling garbage collection of a process over context switches. Newly introduced BIFs: * erlang:garbage_collect/2 - The new second argument is an option list. Introduced option: * {async, RequestId} - making it possible for users to issue asynchronous garbage collect requests. * erlang:check_process_code/3 - The new third argument is an option list. Introduced options: * {async, RequestId} - making it possible for users to issue asynchronous check process code requests. * {allow_gc, boolean()} - making it possible to issue requests that aren't allowed to garbage collect (operation will abort if gc should be needed). These options have been introduced as a preparation for parallelization of check_process_code operations when the code_server is about to purge a module.

2013-02-13Change the return value of hipe_bifs:remove_refs_from/1Kostis Sagonas
In order to avoid an ummatched return warning in erts and make the code more sane, the return value of the bif was changed from [] to 'ok'. (Probably more hipe_bifs need such changes but they will have to wait.) While at it, the code of various functions in hipe_unified_loader was shortened by using lists:foreach/1 instead of explicit recursion.

2012-12-20erts,hipe: Make hipe compiler ask running emulator about process struct offsetsSverker Eriksson
Changes in "struct process" has made native code more depenedent on if the executing emulator is smp enabled or not. This commit will make a default built hipe compiler (without -xcomp) to ask the running emulator about process struct offsets. This will make native code work (again) as long as the same emulator is used for compilation as well as execution of the native code.

2012-06-25hipe_arm.c: remove dead codeMikael Pettersson
erts/emulator/hipe/hipe_arm.c started out as a clone of hipe_ppc.c, with #ifdefs to select ARM-specific code. Somehow those #ifdefs never got cleaned out, resulting in fairly ugly-looking code. This eliminates the #ifdefs, deletes dead PowerPC-specific code, and keeps only the ARM-specific code. I've verified that the exact same assembly code is generated for hipe_arm.c before and after this patch (if you compile without -g, with -g there are unavoidable changes to the debug data).

2012-05-10Remove stale code for hybrid heap and incremental GCBjörn Gustavsson
The hybrid heap emulator was last working in the non-SMP R11B run-time system. When the constant pools were introduced in R12B, the hybrid heap emulator was not updated to handle them. At this point, the harm from reduced readability of the code is greater than any potential usefulness of keeping the code.
