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.
2016-02-15Unify comparison macros in erl_utils.hJosé Valim
This removes the duplication in having both `cmp_eq` and `CMP_EQ` and normalizes their name to uppercase.
2016-02-15Avoid erts_cmp jump in atom, int and float comparisonsJosé Valim
Given the function definition below: check(X) when X >= 0, X <= 20 -> true. @nox has originally noticed that perfoming lt and ge guard tests were performing slower than they should be. Further investigation revealed that most of the cost was in jumping to the erts_cmp function. This patch brings the operations already inlined in erts_cmp into the emulator, removing the jump cost. After applying these changes, invoking the check/1 function defined above 30000 times with different values from 0 to 20 has fallen from 367us to 213us (measured as average of 3 runs). This is a considerably improvement over Erlang 18 which takes 556us on average. Floats have also dropped their time from 1126us (on Erlang 18) to 613us.

* rickard/ds-fixes: Fix unique_SUITE for dirty schedulers Add dirty scheduler process termination test Ensure that work is done on the correct type of schedulers Conflicts: erts/emulator/beam/erl_process.c erts/emulator/beam/erl_process.h erts/emulator/beam/erl_process_dump.c
2016-02-15Fix unique_SUITE for dirty schedulersRickard Green
2016-02-15Add dirty scheduler process termination testSteve Vinoski
In scheduler_SUITE add a new test that runs a single dirty I/O scheduler and launches a number of dirty I/O NIF calls that each sleep for 3 seconds. Given the single scheduler, the first of these will run while the rest queue up. Then start killing these processes, and verify they call exit correctly.
2016-02-15Ensure that work is done on the correct type of schedulersRickard Green
Only the actual call to the dirty nif is allowed to execute on dirty schedulers. The dirty nif is not allowed to execute on normal schedulers if dirty schedulers are available. Arrival of exit signals and system tasks, while a process was scheduled for execution on a dirty scheduler, could mess up the process internal state. Preparation for dirty system task has been made, but is currently unused.

SS_ONSTACK may be set in oss, but it's not supposed to be set in ss, and some systems correctly reject that; current Linux kernels accept but ignore it in ss
