2018-11-09Remove --/2 from dirty BIF testsJohn Högberg
Now that it traps, --/2 would hang forever when building under --enable-dirty-schedulers-test.

2018-11-06beam_trim: Add comments about how all this worksBjörn Gustavsson
Also rename a few functions in attempt to make it clearer.
2018-11-06beam_trim: Recognize more safe labelsBjörn Gustavsson
Recognize more safe labels to enable stack trimming in more circumstances.

2018-11-06beam_utils: Remove unused API functionsBjörn Gustavsson
Remove the now unused beam_utils:is_not_used/3 and beam_utils:is_killed/3 functions and friends. Starting out as simple functions a long time ago, those functions have grown and grown to support more optimizations. The number of bugs found and fixed in beam_utils has also grown over time.
2018-11-06beam_trim: Stop using beam_utils:is_not_used/3Björn Gustavsson
Eliminate the use of beam_utils:is_not_used/3 by implementing a simple is_not_used() function in beam_trim itself. The new version actually makes trimming possible in more circumstances, because beam_utils:is_not_used/3 was too conservative for the purpose of stack trimming (it was previously used for optimizations where it was necessary to be more conservative). Alternatives considered: I tried to implement stack trimming in beam_ssa_codegen but it turned out to be a total mess. Not surprisingly, it turns out that an optimization that renumbers Y registers is hard to do on an intermediate representation that still use variables instead of BEAM registers.
2018-11-06beam_jump: Stop using beam_utils:is_killed/3Björn Gustavsson
Prior to this commit, the optimizations using beam_utils:is_killed/3 were only executed a few times in the entire compiler test suite.

2018-11-06Add a persistent term storageBjörn Gustavsson
Persistent terms are useful for storing Erlang terms that are never or infrequently updated. They have the following advantages: * Constant time access. A persistent term is not copied when it is looked up. The constant factor is lower than for ETS, and no locks are taken when looking up a term. * Persistent terms are not copied in garbage collections. * There is only ever one copy of a persistent term (until it is deleted). That makes them useful for storing configuration data that needs to be easily accessible by all processes. Persistent terms have the following drawbacks: * Updates are expensive. The hash table holding the keys for the persistent terms are updated whenever a persistent term is added, updated or deleted. * Updating or deleting a persistent term triggers a "global GC", which will schedule a heap scan of all processes to search the heap of all processes for the deleted term. If a process still holds a reference to the deleted term, the process will be garbage collected and the term copied to the heap of the process. This global GC can make the system less responsive for some time. Three BIFs (implemented in C in the emulator) is the entire interface to the persistent term functionality: * put(Key, Value) to store a persistent term. * get(Key) to look up a persistent term. * erase(Key) to delete a persistent term. There are also two additional BIFs to obtain information about persistent terms: * info() to return a map with information about persistent terms. * get() to return a list of a {Key,Value} tuples for all persistent terms. (The values are not copied.)
