2016-07-11hipe_sdi: Use segment trees to represent PARENTSMagnus Lång
This speeds up parentsOfChild/2 from O(n) to O(lg n + k). A new module misc/hipe_segment_trees.erl is introduced.
2016-07-11hipe_icode_{bincomp,range}: Improve complexityMagnus Lång
hipe_icode_bincomp:find_bs_get_integer/3 was quadratic for no good reason. By observing that NewSuccs and Rest are always disjoint, we can see that the worklist does not need to be a set. Furthermore, by replacing the ordset Visited with a map, we reduce complexity to (a very low) O(n lg n). On cuter_binlib, this change reduced the time for hipe_icode_bincomp from 60s to .25s. Using a gb_set for Visited gives .5s, and a sets:set 1s. We apply the same optimisation to hipe_icode_range.

This is needed in order for the heap to never contain any pointers to invalid memory. This is good for performance and debugging reasons.

2016-07-08ssl: Correct handling of signature algorithm selectionIngela Anderton Andin
In TLS-1.2 the selection of the servers algorithms and the the possible selection of algorithms for the client certificate verify message have different requirements.
2016-07-08ssl: Simplify and refactor testsIngela Anderton Andin
Tests in ECC_SUITE did not always use the certs implied by the name. Variable naming also confused the intent. ssl_certificate_verify_SUITE did not clean up properly and tests could fail due to cache problems.
2016-07-08erts: Check if return_to trace is enabled for bifLukas Larsson
We have to do an extra check if the return_to trace is enabled here as it may have been cleared by the bif after the flags where created by the call_trace.
2016-07-08[sasl test] Skip tests on slow hostSiri Hansen
release_handler_SUITE:otp_9395_update_many_mods and otp_9395_rm_many_mods often fail on test host 'nain' due to a very slow sys call. These tests are now skipped on this host.
2016-07-08[sasl test] Catch erlang:port_close/1Siri Hansen
After starting a node with open_port({spawn_executable,...},...), the resulting port is closed both automatically and by the calling rh_test_lib:cmd/3. To avoid 'badarg' in the case when the automatic is faster, the call to erlang:port_close/1 is now catched.

Netconf client tests fail every now and then with 'table_trans_timeout' with no obvious reason. A monitor of the maint netconf server process is now added - in case this process crashes during the transaction.

2016-07-04dialyzer: Suppress warns on generated case stmtsMagnus Lång
Warnings about clauses that cannot match and are also compiler generated are suppressed unless none of the clauses return. This feature is useful for non-Erlang BEAM languages (such as Elixir) that compile to Erlang and expand certain language constructs into case statements. In that case, as long as the language construct can succeed, these warnings are undesired and appear spurious to users that do not check the Erlang code that their program expands into. Thanks to José Valim for the test (slightly modified).

2016-07-04edoc: Provide a slightly better fix for unmatched returnsKostis Sagonas
An attempt to shut off Dialyzer's unmatched return warnings made a change that simply ignored the return type of a function. It's arguably better to modify the code of this function to not return something "by accident." While at it, rewrote a slighty confusing use of a list comprehension without a generator to a case statement.

2016-06-30hipe: Fix bug in trap frame allocation wrappersMagnus Lång
The trap frame allocation wrappers occasionally call the garbage collector, even though built-in functions are not supposed to. On non-{x86,amd64} platforms, HiPE was optimising the BIF wrapper interface on the basis that BIFs do not GC. So, when hipe_reserve_beam_trap_frame called the garbage collector, the state in the PCB was stale and corruption happened. Now, these particular BIFs are reclassified as GC BIFs. Unfortunately, in order to do that we needed to introduce a gc_bif_interface_3 macro in every hipe_$ARCH_bifs.m4 file.

2016-06-30hipe: Add assertion for gc in bif without wrapperMagnus Lång
An easy source of tricky bugs is to start calling the garbage collector from a built-in function without adding that bif to hipe_bif_list.m4. With this change we, in the debug build, keep track of whether the canonical stack and heap pointers are stored in the PCB or in registers/stack, allowing us to catch this class of mistakes with an assertion.
