2019-05-21Make the `cpu_sup_SUITE:util_values` test case more reliableKjell Winblad
Previously, the `util_values` test case in the test suite `cpu_sup_SUITE` tested the `cpu_sup:util()` by checking if a process that spins in a loop cause the CPU utilization measured with `cpu_sup:util()` to increase. This was unreliable on test machines that ran other tasks at the same time. This commit tries to make the test case more reliable by skipping the test case if it is detected that the system is doing other work that use a lot of CPU time and starting 100 spinning processes instead of only 1.

2019-05-20Improve optimization of redundant testsBjörn Gustavsson
The `beam_ssa_dead` pass is supposed to eliminate tests that are determined to be redundant based on the outcome of a previous test. For example, in the following example that repeats a guard test, the second clause can never be executed: foo(A) when A >= 42 -> one; foo(A) when A >= 42 -> two; foo(_) -> three. `beam_ssa_dead` should have eliminated the second clause, but didn't: {test,is_ge,{f,5},[{x,0},{integer,42}]}. {move,{atom,one},{x,0}}. return. {label,5}. {test,is_ge,{f,6},[{x,0},{integer,42}]}. {move,{atom,two},{x,0}}. return. {label,6}. {move,{atom,three},{x,0}}. return. Correct the optimization of four different combinations of relational operations that were too conservate. To ensure the correctness of the optimization, also add an exahaustive test of all combinations of relational operations with one variable and one literal. (Also remove the weak and now redundant coverage tests in `beam_ssa_SUITE`.) With this correction, the following code will be generated for the example: {test,is_ge,{f,5},[{x,0},{integer,42}]}. {move,{atom,one},{x,0}}. return. {label,5}. {move,{atom,three},{x,0}}. return. Thanks to Dániel Szoboszlay (@dszoboszlay), whose talk at Code BEAM STO 2019 made me aware of this missed opportunity for optimization.
2019-05-20Fix non-terminating compilationBjörn Gustavsson
The compiler would not terminate while compiling the following code: foo(<<N:32>>, Tuple, NewValue) -> _ = element(N, Tuple), setelement(N, Tuple, NewValue). The type analysis pass would attempt to construct a huge list when attempting analyse the type of `Tuple` after the call to `setelement/3`. https://bugs.erlang.org/browse/ERL-948

2019-05-19Extra -mode flags are ignored with a warningJose M Perez
Prior to this change, providing multiple -mode flags to erl would start the code server as 'interactive', regardless of their value ('-mode embedded -mode embedded' would start erl as in interactive mode). With this change, the extra -mode flags are ignored, and a warning gets logged.

Maybe we should only have specs for external APIs?! This is a how to write spec problem that we have to address later.

2019-05-15ssl: Internal active n must back off when user does not read dataIngela Anderton Andin
TLS connections should not buffer too much application data if they want to benefit from TCP flow control. Certain applications may want to customize the value of internal_active_n as there is a tradeoff between buffering memory and throughput. Conflicts: lib/ssl/src/tls_connection.erl
