2019-02-11Use the counters module to speed up coverBjörn Gustavsson
Use `counters:add/3` instead of `ets:update_counter/3` for counting the number of times a line is executed. By default, the reference to the counter array for each module will be stored in a persistent term and retrieved every time a counter is updated. This makes the compiler test suite with coverage enabled run *almost* twice as fast (on my computer, in about 6 minutes down from more than 11 minutes). To get even more speed, the new `cover:local_only/0` function can be called to put cover into a mode where the cover-compiled code can only be run on the local node. In this mode, the cover-compiled modules in a more efficient way by compiling the counter reference into the code. This shaves off about one more minute, making the compiler test suite with coverage enabled run *more than* twice as fast (in about 5 minutes on my computer).

2019-01-21[cover] Make uncovered lines searchable in html outputSiri Hansen
Prior to PR#1807, uncovered lines could be found by searching for " 0.." in the HTML page generated by cover:analyse_to_file/1,2. The pull request removed the two dots after the number of hits, which makes it much harder to find the uncovered lines. This commit introduces a sad face, :-( , instead of the single 0 character, which should make the search easier.

2018-05-08tools: Handle fast restarts of Xref serverHans Bolinder
2018-05-07Ensure that lcnt server is terminated after lcnt:stop/0John Högberg
This makes the nightly tests slightly more stable as they assert that the server isn't alive when lcnt:start/0 is called, which it could still be since the stop command was a plain gen_server call that didn't wait until the termination was completed.
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).

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.
