2011-12-07erl_driver.h: Use ErlDrvSizeT for size field in ErlIOVecRaimo Niskanen
2011-12-02Iron out bugs in Win64 found in daily buildsPatrik Nyblom
Almost all uses of the 'long' datatype is removed from VM and tests Emulator test now runs w/o drivers crashing Nasty abs bug fixed in VM as well as type errors in allocator debug functions Still one allocator test that fails, domain knowledge is needed to fix that. Fix type inconsistency in beam_load causing crashes
2011-12-02Get cerl and distribution working in Win64Patrik Nyblom
Can still not setup -a, but cerl works.
2011-11-13Use generic lock-free queue for async threadsRickard Green
Queues used for communication between async threads and scheduler threads have been replaced with lock-free queues. Drivers using the driver_async functionality are not automatically locked to the system anymore, and can be unloaded as any dynamically linked in driver. Scheduling of ready async jobs is now also interleaved in between other jobs. Previously all ready async jobs was performed at once.

2010-03-10Adopt the new (R13B04) Nif functionality to the halfword codebasePatrik Nyblom
Change erl_int_sizes_config to include HALFWORD_HEAP_EMULATOR, which make it possible for the NIFs to figure out the term size.
2010-03-10Store pointers to heap data in 32-bit wordsPatrik Nyblom
Store Erlang terms in 32-bit entities on the heap, expanding the pointers to 64-bit when needed. This works because all terms are stored on addresses in the 32-bit address range (the 32 most significant bits of pointers to term data are always 0). Introduce a new datatype called UWord (along with its companion SWord), which is an integer having the exact same size as the machine word (a void *), but might be larger than Eterm/Uint. Store code as machine words, as the instructions are pointers to executable code which might reside outside the 32-bit address range. Continuation pointers are stored on the 32-bit stack and hence must point to addresses in the low range, which means that loaded beam code much be placed in the low 32-bit address range (but, as said earlier, the instructions themselves are full words). No Erlang term data can be stored on C stacks (enforced by an earlier commit). This version gives a prompt, but test cases still fail (and dump core). The loader (and emulator loop) has instruction packing disabled. The main issues has been in rewriting loader and actual virtual machine. Subsystems (like distribution) does not work yet.
