2017-08-14Replace labels instead of inserting duplicates in beam_jumpMichał Muskała
This makes other optimisations more efficient since we have less labels overall.
2017-08-14Enhance elimination of useless tests in beam_jumpMichał Muskała
It can happen we have the following situation: {test,is_tuple,Fail,[R1]} {test,test_arity,Fail,[R1,N1]} {get_tuple_element,R1,N2,R2} {test,is_eq_exaqct,Fail,[R2,Atom]} {jump,Fail} Previously, the optimisation would eliminate the last is_eq_exact test, but we can do more. If the register R2 is not used in Fail, we can eliminate the get_tuple_element instruction as well as all the preceding tests. Ultimately, the whole sequence can be replaced by: {jump,Fail}
2017-08-13Run the sharing optimisation in beam_jump until fixpointMichał Muskała
This is especially useful after inlining a function with a case. Today the compiler would most probably be able to unify all the leafs of the case during the sharing optimisation, but it would fail to unify the pattern matching itself. Naively running the optimisation multiple times wouldn't be able to find the common code either, because it would differ in jump/fail targets of various instructions. To remedy this, after doing each sharing pass we traverse the code backwards when reversing and update all the jump targets with the new targets that were discovered during the unification pass. This allows running the optimisation until fixpoint and makes sure all sharing opportunities will be discovered. This optimisation also helps with the Elixir's `with/else` construct.

2017-08-10ssl: Correct cipher suite handlingIngela Anderton Andin
This is mainly fixing the test suites so that they test the intended cipher suites, issue reported in ERL-460. Also ssl_cipher:anonymous_suites was corrected for DTLS.

2017-08-08ssl: Handle OpenSSL output correctlyIngela Anderton Andin
Adjust to handle output from OpenSSL in a more general way, so that "unknown option" should be caught for all cases and the test case skipped if that is the case and other data form OpenSSL should be ignored.

2017-08-07sys_core_fold: Fix unsafe optimization of non-variable applyBjörn Gustavsson
The sys_core_fold pass would do an unsafe "optimization" when an apply operation did not have a variable in the function position as in the following example: > cat test1.core module 'test1' ['test1'/2] attributes [] 'i'/1 = fun (_f) -> _f 'test1'/2 = fun (_f, _x) -> apply apply 'i'/1 (_f) (_x) end > erlc test1.core no_file: Warning: invalid function call Reported-by: Mikael Pettersson
