2018-04-23erts: Rewrite memory instrumentationJohn Högberg
This commit replaces the old memory instrumentation with a new implementation that scans carriers instead of wrapping erts_alloc/erts_free. The old implementation could not extract information without halting the emulator, had considerable runtime overhead, and the memory maps it produced were noisy and lacked critical information. Since the new implementation walks through existing data structures there's no longer a need to start the emulator with special flags to get information about carrier utilization/fragmentation. Memory fragmentation is also easier to diagnose as it's presented on a per-carrier basis which eliminates the need to account for "holes" between mmap segments. To help track allocations, each allocation can now be tagged with what it is and who allocated it at the cost of one extra word per allocation. This is controlled on a per-allocator basis with the +M<S>atags option, and is enabled by default for binary_alloc and driver_alloc (which is also used by NIFs).

Split the manual testcase and run them in daily tests instead. Easy to run directly as well: (cd ../test; cerl -eval "emacs_SUITE:indent([])")

2018-02-12Automatically start lcnt server on first useJohn Högberg
lcnt:collect is documented as implicitly starting the lcnt server but didn't do so prior to this commit. I've decided to extend this behavior to all operations as the overhead is negligible and it's a bit more convenient to use.

2017-11-30Fix incorrect assumption about process activityJohn Högberg
The tests assume that the most active process will be the current one, which is no longer true since the delayed_write option now uses a wrapper process for much of its work. The timeout for this test has been increased to account for the lack of delayed_write; 60s was enough for everything except the debug build on some machines.
2017-10-27Correct erlang:is_builtin/3 for apply/2 and yield/0Björn Gustavsson
erlang:is_builtin(erlang, M, F) returns false for apply/2 and yield/0. The documentation for erlang:is_builtin/3 says that it returns true for BIFs that are implemented in C. apply/2 and yield/0 are implemented in C (as BEAM instructions), and therefore the correct return value is true. Also see a similar argument that was made for apply/3 in the past: http://erlang.org/pipermail/erlang-bugs/2015-October/005101.html https://bugs.erlang.org/browse/ERL-500

2016-08-29Fix purge of codeRickard Green
Ensure that we cannot get any dangling pointers into code that has been purged. This is done by a two phase purge. At first phase all fun entries pointing into the code to purge are marked for purge. All processes trying to call these funs will be suspended and by this we avoid getting new direct references into the code. When all processes has been checked, these processes are resumed. The new purge strategy now also completely ignore the existence of indirect references to the code (funs). If such exist, they will cause bad fun exceptions to the caller, but will not prevent a soft purge or cause a kill of a process having such live references during a hard purge. This since it is impossible to give any guarantees that no processes in the system have such indirect references. Even when the system is completely clean from such references, new ones can appear via distribution and/or disk.
