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.

2014-03-12cerl_inline: Fix type errorBjörn Gustavsson
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.

2014-03-10Properly handle redundant boolean clauses in sys_core_foldAnthony Ramine
Boolean case expressions with redundant clauses could make the compiler crash: case X == 0 of false -> no; false -> no; true -> yes end. Reported-by: Ulf Norell

2014-03-06Do not emit blatantly illformed apply expressions in core_inlineAnthony Ramine
Code such as apply 'f'/1 () should not be emitted by the Core Erlang inliner. Commit 1b8ad68361db59477013bf96e485d5293723ff42 added a test case and correction in v3_core.

2014-03-05Do not export variables from comprehension cases in v3_coreAnthony Ramine

2014-03-05Compile BIF calls and operator expressions to Core the same wayAnthony Ramine
Previously, erlang:'or'(X, Y) and X or Y were not compiled to the same Core code.
2014-03-05Do not try to optimize non-boolean guardsAnthony Ramine
Expressions such as erlang:'or'(bar, true) can make beam_bool crash if it tries to optimize them, as this code is not quite really written by users, no attempt to rewrite them more efficiently should be done, for simplicity's sake. Reported-by: Ulf Norell

2014-03-04Support maps in cerl_clauses:match/2Anthony Ramine
Without this, sys_core_fold could crash on non-matching clauses using maps patterns. Reported-by: Ulf Norell
2014-03-04Properly order Kernel code for maps with mixed pairsAnthony Ramine
The Kernel instructions were not properly ordered when compiling maps with complex values mixed in assoc and exact pairs. Reported-by: Ulf Norell
2014-03-04Properly sort map pairs in v3_codegenAnthony Ramine
Literal nil values aren't tagged tuple but the bare atom nil. The function lists:sort/2 expects the passed function to return true if the first element is less than or equal to the second, not strictly less than. The original base clause is changed accordingly. Reported-by: Ulf Norell
2014-03-04Properly lint calls in Core Erlang guardsAnthony Ramine
Not all calls to the erlang module are legal guards in Core Erlang.

2014-03-04Introduce compiler option 'nowarn_deprecated_type'Hans Bolinder
The deprecation of the built-in types dict/0 and so on had as side-effect that it was impossible to switch to dict:dict/2 and so on without getting warnings either in the the previous release (R16B) or the current one (17.0). By including the attribute -compile(nowarn_deprecated_type). in an Erlang source file warnings about deprecated types can be avoided in 17.0. The option can also be given as a compiler flag: erlc +nowarn_deprecated_type file.erl

2014-03-03Do not mark all calls to erlang:is_function/2 as safeAnthony Ramine
Calls to erlang:is_function/2 where the second is not a literal nonnegative integer can crash at runtime and thus can't be marked as safe.
2014-03-02Do not mark all calls to erlang:is_record/3 as safeAnthony Ramine
Calls to erlang:is_record/3 where the second and third arguments are not respectively a literal atom and a literal integer can't be transformed to guards and thus are not safe. Reported-by: Ulf Norell
2014-03-01Do not emit blatantly illformed Core Erlang apply expressionsAnthony Ramine
