2014-03-25compiler: Do not evaluate map expressions with bad keysBjörn-Egil Dahlberg
Map keys with large (non literal) binary keys must fail.
2014-03-25compiler: Throw 'nomatch' on matching with bad binary keysBjörn-Egil Dahlberg
Even if a binary key is written as a literal the compiler may choose to make an expression. Emit a warning in those cases and saying the case will not match. This is a limitation in current implementation.
2014-03-25compiler: Variable keys are not allowed in MapsBjörn-Egil Dahlberg
No need to check for variables in Map keys.
2014-03-25compiler: Strengthen Maps warnings testsBjörn-Egil Dahlberg
Increases coverage.
2014-03-25compiler: map_pair cannot be a type clause in v3_lifeBjörn-Egil Dahlberg
Map pairs are encapsulated in a map.
2014-03-25Correctly handle non-matching patterns against literal valuesAnthony Ramine
The pass sys_core_fold did not correctly handle non-matching patterns in code such as: 0 = case <<>> of <<>> -> 0; a -> 1 end. Function case_opt_lit/3 is rewritten in two passes to first remove any non-matching clause and only then potentially remove the related patterns in each clause. Reported-by: Ulf Norell

2014-03-24compiler: Test deep map structureBjörn-Egil Dahlberg
2014-03-24compiler: Remove redundant clause in v3_codegenBjörn-Egil Dahlberg
Multiple 'nil' cannot happen on instruction level. Map keys are always unique with literals.
2014-03-24compiler: Cover #{ [] => Var } in testcaseBjörn-Egil Dahlberg
Coverage removed by literals.
2014-03-20Introduce runtime_dependencies in .app filesRickard Green
Most dependencies introduced are exactly the dependencies to other applications found by xref. That is, there might be real dependencies missing. There might also be pure debug dependencies listed that probably should be removed. Each application has to be manually inspected in order to ensure that all real dependencies are listed. All dependencies introduced are to application versions used in OTP 17.0. This since the previously used version scheme wasn't designed for this, and in order to minimize the work of introducing the dependencies.
2014-03-20Bump versions and ensure that all are "normal" versionsRickard Green
Ensure all are "normal" versions according to the new version scheme introduced in OTP 17.0

* bjorn/compiler/utf8-warning/OTP-11791: Don't fail compilation for modules that contain invalid UTF-8 epp: Make it possible to specify a default encoding
2014-03-19Restore the alphabetical order of Core Erlang recordsKostis Sagonas
The introduction of c_map{} and c_map_pair{} unnecessarily broke the alphabetical order of Core Erlang records. They were probably placed at the end of the file so as to use other records as types. There is really no need for this since 'cerl' contains appropriate definitions of types that can be used for this purpose. While at it, a type declaration to the c_binary{} definition was added.
2014-03-19Clean up the types of cerlKostis Sagonas
The introduction of c_map and c_map_pair was not done properly. In particular, the definition of ctype() and an important Edoc comment were not up-to-date. While at it, - some more types were cleaned up and exported so as to be used in core_parse.hrl and - some obviously dead code was removed (the type/1 function does not return 'nil', which in turn simplified a clause in the code of meta_1/2).
2014-03-18Don't fail compilation for modules that contain invalid UTF-8Björn Gustavsson
The default encoding for Erlang modules is now UTF-8, and the compilation would fail if a module contained byte sequences that are not valid UTF-8 sequences. In a large project with say many hundreds of Erlang modules with names of developers such as "Björn" or "Håkan" encoded in latin-1, that could mean that many hundreds of files would need to be modified just to get started testing OTP 17. As a temporary measure to ease the transition, automatically fall back to the latin-1 encoding with a warning for any module that contains invalid byte sequences and for which no encoding has been specified. The intention is to remove this workaround in OTP 18 or 19.

2014-03-17compiler: Transform M#{} to is_map(M)Björn-Egil Dahlberg
Core should not understand M#{} Instead transform M#{} to case _cor0 of <_cor1> when call 'erlang':'is_map' (_cor0) -> _cor1 ( <_cor2> when 'true' -> primop 'match_fail' ('badarg') -| ['compiler_generated'] ) end
2014-03-17compiler: Change #c_map{var} to #c_map{arg}Björn-Egil Dahlberg
Not only variables are allowed as arguments, the name should reflect that. Change cerl Map argument interface * cerl:map_arg/1 is more suitable then cerl:map_val/1 in this case.
2014-03-17compiler: Constant fold Maps that are safeBjörn-Egil Dahlberg
For updates of Map literals which may cause an error will be determined in runtime, i.e. instructions are emitted for those updates. The changes in cerl now requires compiler-5.0 to compile because of is_map/1 guard.
2014-03-17compiler: Validate Map srcBjörn-Egil Dahlberg
Reject all expressions that are known to fail. Emit 'badarg' for those expressions. Ex. []#{ a => 1} Is not a valid map update expression.
2014-03-17compiler: Support literal maps in cerl_clauses:match/2Björn-Egil Dahlberg
2014-03-17compiler: Guard BIF is_map/1 is pureBjörn-Egil Dahlberg
2014-03-17compiler: Change Maps Core FormatBjörn-Egil Dahlberg
Ex. Instead of: M~{~<K,V>}~ The format is now: ~{~<K,V>|M}~ This also removes a shift/reduce warning. The changes in core_pp now requires compiler-5.0 to compile because of is_map/1 guard, i.e. a need for a compiler with Maps know-how.

b08ffc15e1d9ad105dd6385bbac41c97c09b48bc corrected a bug, but violated the types by passing a c_apply() when a c_let() was expected. That happened to work, but Dialyzer was not amused.
