2016-02-17Makefiles: Remove test_server from include path and code pathBjörn Gustavsson
Since no test suites includede test_server.hrl, there is no need to have test_server in the include path or code path.
2016-02-17Eliminate use of test_server.hrl and test_server_line.hrlBjörn Gustavsson
As a first step to removing the test_server application as as its own separate application, change the inclusion of test_server.hrl to an inclusion of ct.hrl and remove the inclusion of test_server_line.hrl.

2016-02-02Better list_to_integerDmytro Lytovchenko
Now tries to use whole width of signed long (Sint) and this halves amount of multiplications needed to parse long integers. New code is 2-3 times faster than the old code for large inputs (tens and hundreds of digits), behavior should not change for small inputs. Test ran 10k times with GC forced between attempts.

perf counter is now part of the function pointer interface and also the function returns the value instead of writing to a memory buffer.

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
2016-02-02erts: Add ERTS_WRITE_UNLIKELYLukas Larsson
ERTS_WRITE_UNLIKELY can be used to place global variables in a specific section where only data that is very rarely modified sits. This is used to improve cache locality.
