to provoke case when the main lock is released during execution.
2019-06-10erts: Fix bad loader optimization of get_tuple_elementJohn Högberg
The following sequence would be wrongly optimized into a i_get_tuple_element2 instruction, reading an element from the wrong tuple: {get_tuple_element,{x,0},1,{x,0}}. {get_tuple_element,{x,0},2,{x,1}}.
2019-06-10beam_ssa_type: Fix incorrect bitstring unit determinationJohn Högberg
The compiler would treat the "Unit" of bs_init instructions as the unit of the result instead of the required unit of the input, causing is_binary checks to be wrongly optimized away.

2019-06-04Revert "erts: Force process_info(reductions) as signal"Sverker Eriksson
This reverts commit 70dbf671a8196110d2aee2e7507afc2c2c75183f. As the comment of 70dbf671a8 itself indicates, that "fix" is not really necessary. It has, however, the bad effect of always consuming reductions of the process you want to know reduction from, that is you can't meassure reduction count without affecting it.

2019-05-28Fix 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.
2019-05-28Eliminate crash in the beam_ssa_dead compiler passBjörn Gustavsson
The compiler could crash in the beam_ssa_dead pass while compiling complex nested `case` expressions. See the added test case for an example and explanation. https://bugs.erlang.org/browse/ERL-956
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
2019-05-27compiler: Fix broken type for erlang:'++'/2John Högberg
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
2019-05-24Fix 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.
2019-05-23Fix sticky class in exceptionBjörn Gustavsson
When catching an exception re-throwing with a changed class, the class could be changed to the original class if the exception got caught and rethrown in (for example) an after block: sticky_class() -> try try throw(reason) catch throw:Reason:Stack -> erlang:raise(error, Reason, Stack) end after ok end.
2019-05-22crypto: Re-enable aes_ctr for openssl cryptolib < 1.0.1Hans Nilsson
It was accidently disabled in the crypto:supports/0 and /1. It worked however in the encrypt/decrypt functions.
2019-05-21Eliminate compiler crash when compiling complex receive statementsBjörn Gustavsson
Certain complex receive statements would result in an internal compiler failure. That would happen when the compiler would fail to find the common exit block following a receive. See the added test case for an example. https://bugs.erlang.org/browse/ERL-950
2019-05-20Fix non-terminating compilationBjörn Gustavsson
The compiler would not terminate while compiling the following code: foo(<<N:32>>, Tuple, NewValue) -> _ = element(N, Tuple), setelement(N, Tuple, NewValue). The type analysis pass would attempt to construct a huge list when attempting analyse the type of `Tuple` after the call to `setelement/3`. https://bugs.erlang.org/browse/ERL-948
