2016-02-09dialyzer: Correct byte_size() and comparisonsHans Bolinder
The argument of byte_size() is a bitstring(). The code in erl_bif_types that finds cases where comparisons always return true or false is corrected when it comes to maps and bit strings.

2016-02-08dialyzer: Fix a bug concerning the option 'plt_remove'Hans Bolinder
[James Fish:] Dialyzer always asserts that files and directories passed in its options exist. Therefore it is not possible to remove a beam/module from a PLT when the beam file no longer exists. Dialyzer should not to check files exist on disk when removing from the PLT.

2016-02-03Speed up supervisor:count_children/1; simple_one_for_oneRory Byrne
Speed up supervisor:count_children/1 for simple_one_for_one supervisors. This is achieved by avoiding looping through all the child process and verifying that each one is alive. For a supervisor with 100,000 'temporary' children the count-time will drop from approx 25ms to about 0.005ms. For a supervisor with 100,000 'permanent' or 'transient' children the count-time will drop from approx 30ms to about 0.005ms. This avoids having the supervisor block for an extended period while the count takes place. Under normal circumstances the accuracy of the result should also improve since the duration is too short for many processes to die during the count.
2016-02-03Add supervisor:get_callback_module/1Siri Hansen
This function is used by release_handler during upgrade. This was earlier implemented in the release_handler, but it required a copy og the definition of the supervisor's internal state, which caused problems when this state was updated.
2016-02-03v3_core: Eliminate double processing of patternsBjörn Gustavsson
Internally in the v3_core pass, an #imatch{} record represents a match expression: Pattern = Expression If Pattern is a single, unbound variable, #imatch{} will be rewritten to #iset{}; otherwise it will be rewritten to #icase{}. To determine how #imatch{} should be translated, the pattern is processed using upattern/3. The return value from upattern/3 is thrown away (after having been used for determing how the #imatch{} record should be translated). That means that every pattern in an #imatch{} is processed twice, which is wasteful. We can easily avoid the double processing of patterns by introducing a new helper function that determines whether the pattern is a new variable.

2016-02-03tools: Add a Cover testHans Bolinder
2016-02-03tools: Fix wrong instrumentation of binary comprehensionsLuis Rascao
When cover instruments binary comprehensions it's generating a {block, ...} abstract code term inside a {bc, ...} term that is causing the evaluation to fail at runtime. Removing the block statement eliminates the error. The template of a bit string comprehension cannot have a counter since it is not allowed to be a block.

2016-02-02erts: Add microstate accountingLukas Larsson
Microstate accounting is a way to track which state the different threads within ERTS are in. The main usage area is to pin point performance bottlenecks by checking which states the threads are in and then from there figuring out why and where to optimize. Since checking whether microstate accounting is on or off is relatively expensive if done in a short loop only a few of the states are enabled by default and more states can be enabled through configure. I've done some benchmarking and the overhead with it turned off is not noticible and with it on it is a fraction of a percent. If you enable the extra states, depending on the benchmark, the ovehead when turned off is about 1% and when turned on somewhere inbetween 5-15%. OTP-12345
2016-02-02erts, kernel: Add os:perf_counter functionLukas Larsson
The perf_counter is a very very cheap and high resolution timer that can be used to timestamp system events. It does not have monoticity guarantees, but should on most OS's expose a monotonous time. A special instruction has been created for this counter to further speed up fetching it. OTP-12908
