2019-02-20ssl: Reintroduce documentation of signature_algs_cert and log_level optionIngela Anderton Andin
When changing the ssl application to use type specs in documentation master additions where lost in the merge as we did not want to rewrite the new documentation in a merge commit.
2019-02-20Improve optimization of switchesBjörn Gustavsson
Part of the switch optimization done by `ssa_opt_sw` can be better done in `beam_ssa_type`.

2019-02-20Refactor optimization of Bool =:= trueBjörn Gustavsson
Refactor optimization of `Bool =:= true` to make the code somewhat simpler, as well as potentially apply the optimization in more cases.
2019-02-20Always make andalso/orelse right-associativeBjörn Gustavsson
Always rewriting left-associative andalso/orelse to right-associative will not change the code (except in very rare cases), but it will make sure that the transformation is tested.

2019-02-19Do the destructive setelement optimization in SSABjörn Gustavsson
The expansion of record field updates, when more than one field is updated, but not a majority of the fields, will create a sequence of calls to `erlang:setelement(Index, Value, Tuple)` where Tuple in the first call is the original record tuple, and in the subsequent calls Tuple is the result of the previous call. Furthermore, all Index values are constant positive integers, and the first call to `setelement` will have the greatest index. Thus all the following calls do not actually need to test at run-time whether Tuple has type tuple, nor that the index is within the tuple bounds. Since OTP R7, the `sys_core_dsetel` pass, run as the very last Core Erlang pass, has optimized this sequence of `setelement` calls to use a special destructive version of `setelement` (called `set_tuple_element`) for all but the very first `setelement` in the sequence. It turns out that the presence of the `set_tuple_element` in SSA code is awkward and can prevent or complicate type analysis and aggressive optimizations. Therefore, this commit removes the `sys_core_dsetel` pass and reimplements it for SSA code. The optimization will be done in the `beam_ssa_pre_codegen` pass (that is, just before code generation and after running all other SSA code optimization passes). In most cases, the resulting BEAM code is identical to previous code. For a few modules, the BEAM code is actually slightly better, with smaller stack frames.

Also make a weaker spec in ssl_internal.hrl for now as it creates a conflict between error handling and dialyzer warnings.
2019-02-18ssh: Refactor decryption in ssh_protocol_SUITEHans Nilsson
Previously this test suite used a short-cut that didn't work well with the new crypto API being experimented with in other branches. This commit uses the legacy decode and decryption functions in ssh_transport. It is of course normally a bad idea to test something with itself. However, other test suites test the interoperability with OpenSSH and by that implicitly of the decoding/decryption. The ssh_protocol_SUITE tests sending malformed and even malicious PDUs to the Erlang/OTP SSH implementation. Therefore the tests in this suite is not dependent on being different than thoose of the system under test.
2019-02-18compiler: Allow disabling SSA passes in -compile() directivesJohn Högberg
This fixes compiling against older OTP versions with the +r?VSN options, which often expand to disabling certain SSA passes to avoid new instructions.
