2017-07-07Add stacktrace entries to BIF calls from emulatorJosé Valim
The goal of this change is to improve debugging of emulator calls. For example, the following code rem(1, y) will error with atom `badarith` when y is 0 and the stacktrace has no entry for `erlang:rem/2`, making such cases very hard to debug. This patch makes it so the stacktrace includes `erlang:rem(1, 0)`. The following emulator BIFs have been changed: * band/2 * bnot/1 * bor/2 * bsl/2 * bsr/2 * bxor/2 * div/2 * element/2 * int_div/2 * rem/2 * sminus/2 * splus/2 * stimes/2

2017-05-18Allow multiple types per argument for specific instructionsBjörn Gustavsson
Inroduce syntactic sugar so that we can write: get_list xy xy xy instead of: get_list x x x get_list x x y get_list x y x get_list x y y get_list y x x get_list y x y get_list y y x get_list y y y
2017-05-18Eliminate the -gen_dest macro flagBjörn Gustavsson
Instructions that take a 'd' argument needs a -gen_dest flag in their macros. For example: %macro:put_list PutList -pack -gen_dest put_list s s d -gen_dest was needed when x(0) was stored in a register, since it is not possible to take the address of a register. Now that x(0) is stored in memory and we can take the address, we can eliminate gen_dest.

2017-05-05erts: the esdp is not always available in matchspecLukas Larsson
This happens for instance when a receive_trace is run in the sys_msg_dispatcher thread when the trace_delivered trace message is traced.
2017-05-05Clear p->fvalue when handling a try/catchBjörn Gustavsson
p->fvalue will be set by BIFs that generate exceptions (such as throw/1), and it will not be cleared before another exception is generated. Potentially, p->fvalue may contain a huge term (e.g. after throw(HugeTerm)) which will be kept in the heap. We can shorten the lifetime of f->value by clearing it in the instructions that handle catches: catch_end and try_end. That is safe because BEAM code will never access p->fvalue. If BEAM code needs to rethrow an exception it will use a reference to the value passed in an X register. The reason that p->fvalue must not be cleared already in handle_error() is that native code trap handlers will use it. (See the comment before handle_error() and the comment at the end of handle_error() in beam_emu.c for some more information about exception handling.)

2017-04-18Timer wheel divided into a "soon wheel" and a "later wheel"Rickard Green
The old single wheel implementation handled about 65 seconds. The new dual wheel implementation handles more than 37 hours. The dual wheels have also been shrunk compared to the single wheel, so the total memory consumption for timer wheels have been cut in half.
