2019-05-27Fix compiler crash in beam_exceptBjörn Gustavsson
The compiler would crash in `beam_except` while compiling this function: bar(Req) -> ok = case Req of "POST" -> {error, <<"BAD METHOD ", Req/binary>>, Req}; _ -> ok end. https://bugs.erlang.org/browse/ERL-954

2019-05-27Fix loading of Core Erlang code for extracting a map elementBjörn Gustavsson
The following Core Erlang code could not be loaded: 'f'/1 = fun (_1) -> case <_1> of <~{'foo':='foo'}~> when 'true' -> _1 end Loading would fail with the following message: beam/beam_load.c(2314): Error loading function example:f/1: op i_get_map_element_hash p x a u x: no specific operation found https://bugs.erlang.org/browse/ERL-955
2019-05-25Fix unsafe optimizations where guard tests could be removedBjörn Gustavsson
A repeated test could be optimized away. Example: bar(A) -> if is_bitstring(A) -> if is_binary(A) -> binary; true -> bitstring end; true -> other end. In the example, the `is_binary/1` test would be optimized away, basically turning the example into: bar(A) -> if is_bitstring(A) -> bitstring; true -> other end. Thanks user Marcus Kruse in the Elixir forum for noticing this bug.

2019-05-24Fix unsafe negative type inferenceBjörn Gustavsson
The type optimizer pass (`beam_ssa_type`) could make unsafe negative inferences. That is, incorrectly infer that a variable could *not* have a particular type. This bug was found when adding another optimization. It is not clear how write a failing test case without that added optimization.

2019-05-23ETS testing: Improve visualization of ETS throughput benchmark resultsKjell Winblad
This commit makes it possible to see relative differences in the HTML page that visualizes results from the ETS throughput benchmark that is included in the test suite ets_SUITE. This change will make it easier to compare different ETS table configurations and implementations.

2019-05-23Implement '==' optimization in beam_ssa_typeBjörn Gustavsson
`=:=` is faster than `==`, so when they would return the same result, we want to replace `==` with `=:=`. There is currently such an optimization in sys_core_fold, but the optimimization will be more effective if done in beam_ssa_type because beam_ssa_type has better type information.
