2017-02-03Store messages for 'rex' and 'error_logger' off heapBjörn Gustavsson
Performance for processes that receive huge amounts of messages can be increased by storing the incoming messages outside the heap (that avoids copying the message in a garbage collection). Two OTP processes that are known to receive many messages are 'rex' (used by 'rpc') and 'error_logger'.

2017-02-03dialyzer: Attempt to reduce memory consumptionHans Bolinder
The 'deps' field is reset when no longer used, which could possibly save some memory.
2017-02-03dialyzer: Do not spawn all workers at onceHans Bolinder
Spawning all worker processes at once has the potential to increase peak memory consumption. Therefore the implementation is now slightly modified: `20 * dialyzer_utils:parallelism()' processes are running in parallel. 20 i quite a big factor, but seems necessary to keep all schedulers busy according to the Observer application's Load Charts, with a 100 ms update interval.
2017-02-03dialyzer: Write PLT in subprocessHans Bolinder
At common case, which will otherwise leave a big heap.
2017-02-03dialyzer: Remove code for non-started workersHans Bolinder
Since SCCs and modules are now topologically sorted (relative the active graph), we can safely assume that workers have been started.
2017-02-03dialyzer: Sort graphs topologicallyHans Bolinder
Although some variable names indicate that lists of SCCs and modules are sorted, that was not always the case. The effect on the execution time of sorting them doesn't seem to be significant. dialyzer_coordinator:sccs_to_pids() should now always return an empty second list (not yet started workers). Since the condensation of graphs often needs a lot of heap memory, it is run in a separate process.
2017-02-03dialyzer: Compress some PLT tablesHans Bolinder
Compressing the signatures or the contract records would cost time. The contract records are still held in two places (code server and PLT) in many cases.
2017-02-03dialyzer: Check return value of digrahp:add_edge()Hans Bolinder
2017-02-03dialyzer: Use less memory for the PLT when analyzingHans Bolinder
The two tables for (record) types and exported types are no longer kept in memory (by the PLT) when analyzing, which reduces memory consumption. A first step towards removing (or replacing) the #plt{} record.
2017-02-03typer: Fix a bug regarding the -T optionHans Bolinder
The -T option has not been working for a long time.
2017-02-03dialyzer: Do not keep the code server's type info on the heapHans Bolinder
The table used during translation of forms to types used to be a dictionary of the type info (-type(), -opaque(), and -record()) for all modules. Now it is reduced to the modules that are needed to handle references to types in other modules. The PLT:s type info is still kept on the heap.
