2017-05-22erts: Optimize etp-processes and etp-portsLukas Larsson
Not calculating the max, table and invalid addresses each loop speeds up iterating through the processes list by about 5x.

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
2017-05-18Modernize subroutine calls by removing '&'Björn Gustavsson
In Perl 5, '&' on direct subroutine calls are optional.
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.

2017-05-16Teach erlexec the -emu_type optionBjörn Gustavsson
Add the option -emu_type to start an emulator of a certain type. For exampe, "-emu_type lcnt" will start beam.lcnt.smp. Any string will be accepted after -emu_type. If there is no corresponding emulator, there will be an error similar to: erlexec: The emulator '.../bin/x86_64-unknown-linux-gnu/beam.foo.smp' does not exist. On Windows, there is an undocumented option "-debug". Remove that option, because -emu_type can be used instead.
2017-05-16Let --enable-lock-counter build an additional emulatorBjörn Gustavsson
"./configure --enable-lock-counter" would modify the behavior of the default emulator (usually SMP). To make lock counting more accessible, change --enable-lock-counter to build an additional emulator in the same way as: (cd erts/emulator && make lcnt) (The next commit will make it easier to start the built lock-counter emulator.)

2017-05-12Warn for potentially unsafe use of get_stacktrace/0Björn Gustavsson
erlang:get_stacktrace/0 returns the stacktrace for the latest exception. The problem is that the stacktrace is kept until the next exception occurs. If the last exception was a 'function_clause' or a 'badarg', the arguments for the call are also kept forever. The arguments can be terms of any size (potentially huge). In a future release, we would like to only allow erlang:get_stacktrace/0 from within a 'try' expression. That would make it possible to clear the stacktrace when the 'try' expression is exited. The 'catch' expression has no natural end where the stacktrace could be cleared. The stacktrace could be cleared at the end of the function that the 'catch' occurs in, but that would cause problems in the following scenario (from real life, but simplified): try ... catch _:_ -> io:format(...), io:format("~p\n", [erlang:get_stacktrace()]) end. %% In io.erl. format(Fmt, Args) -> Res = case ... of SomePattern -> catch... ...; SomeOtherPattern -> %% Output the formatted string here ... end, clear_stacktrace(), %% Inserted by compiler. Res. The call to io:format() would always clear the stacktrace before it could be retrieved. That problem could be solved by tightning the scope in which the stacktrace is kept, but the rules for how long erlang:get_stacktrace/0 would work would become complicated. Therefore, the solution we suggest for a future major release of OTP is that erlang:get_stacktrace/0 will return [] if it is called outside the 'catch' part of a 'try' expression. To help users prepare, introduce a warning when it is likely that erlang:get_stacktrace/0 will always return an empty list, for example in this code: catch error(foo), Stk = erlang:get_stacktrace() or in this code: try Expr catch _:_ -> ok end, Stk = erlang:get_stacktrace()
