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

2016-01-29Eliminate redundant double is_function testBjörn Gustavsson
When tuple funs were still supported, the idiom for allowing real funs with a certain arity but not tuple funs was: is_function(Fun) andalso is_function(Fun, Arity) The reason that both tests were needed is because: is_function({M,F}) would return 'false' is_function({M,F}, Arity) would return 'true' In 53ec991d19, is_function/2 was updated to only return 'false' for tuples, so the call to is_function/1 can be removed.

2016-01-28Extend cerl_trees:mapfold with a 'pre-order' operationStavros Aronis
When manipulating Core Erlang trees it may be useful to perform some operation when a node is visited, before inspecting children nodes. The definition of cerl_tree:mapfold/3 does not allow that, as it applies the given function only after all the recursive calls on the children nodes have been completed. This patch adds a new argument to mapfold: a function that is applied when a node is first entered. As an example of its use, consider the case where one wants to move a 'call' node earlier, by adding 'let' node and replacing the 'call' node with the defined variable. The name of that variable must be specified before one traverses the inner tree (especially if such replacements can be nested).
2016-01-28Use file read buffering in dbg:trace_clientPéter Gömöri
Trace files are typically large but contain small terms so we can expect a performance gain from read buffering. dbg:trace_client with a dummy handler ran more then 3x faster on a sample 200MB trace file. fprof:profile can also gain a bit.

2016-01-28code: Correct the types for error returnsBjörn Gustavsson
The specifications for functions that load code in the 'code' module (e.g. code:load_file/1) have some problems: * The specs claim that the functions can return {error,on_load}, but they never do. However, they can return {error,on_load_failure} if the -on_load function in a module fails. * The specs claim that the functions can return {error,native_code}, but they never do. While we are it, also extend the on_load_errors/1 test case to test that the load functions return {error,on_load_failure} when an -on_load function fails.
2016-01-27code_server: Add types to the state recordBjörn Gustavsson
2016-01-27code_server: Don't export internal system_* functionsBjörn Gustavsson
There is no reason to export system_continue/3 and system_terminate/4 from code_server. Servers that use proc_lib and 'sys' to handle system message do need those functions exported, but code_server contains a modified copy of the system message handling code from 'sys', and that code only make local calls to system_continue/3 and system_terminate/4.
2016-01-27Simplify starting of code serverBjörn Gustavsson
There is unnecessary knowledge about the -nostick option in the 'kernel' module. -nostick can be handled entirely in the 'code' module. There is no need to have both code:start_link/0 and code:start_link/1. code:start_link/0 is sufficient. Also get rid of error handling for things that cannot happen: The 'init' module has made sure that init:get_argument(root) can't fail, so there is no need for any error-reporting code. (See e1dc0aa4.) We also don't need to test the return value from code_server:start_link/1, because it will always return {ok,Pid} (or crash).

2016-01-27Remove first argument of code_server:call()Björn Gustavsson
Remove the first argument for code_server:call(). It makes no sense. The only caller is 'code'. Note that the code_server module is undocumented and that code_server:call() is an internal helper function.
