2014-04-17hipe, dialyzer: Fix a bug concerning opaque typesHans Bolinder
Dialyzer sometimes output warnings like Attempt to test for inequality between a term of type 'false' and a term of opaque type 'false' | gb_set() The reason was that erl_types:t_inf/3 when called from erl_types:t_find_unknown_opaque() did not return 'false' but found the mismatch. It should not return the mismatch unless the intersection is empty ('none'). Thanks to Shayan Pooya [[email protected]] for pointing out the bug.
2014-03-28Add support for the compilation of the is_map/1 guard to native codeKostis Sagonas
Namely, extend the HiPE tagging scheme info, properly handle the translation of the (is_)map type test to Icode and RTL and support handling of the map() type in the type system. While at it, also performed some clean up of things that needed small fixes.

2014-03-05Add types for new HiPE BIFsKostis Sagonas
Commit 81c7db0e247a6ee1b7a5c2764aa9575d7f6fb88a broke apart hipe_bif:make_fe/3 into two BIFs but forgot to properly update the type information about HiPE BIFs in erl_bif_types.erl. This commit fixes this by taking out the types of hipe_bifs:make_fe/3 and adding types for the new BIFs hipe_bifs:get_fe/2 and hipe_bifs:hipe_bifs_set_native_address_in_fe/2.

2014-02-24Added support for ENEA OSELukas Larsson
This port has support for both non-smp and smp. It contains a new way to do io checking in which erts_poll_wait receives the payload of the polled entity. This has implications for all linked-in drivers.
2014-02-23Deprecate pre-defined built-in typesHans Bolinder
The types array(), dict(), digraph(), gb_set(), gb_tree(), queue(), set(), and tid() have been deprecated. They will be removed in OTP 18.0. Instead the types array:array(), dict:dict(), digraph:graph(), gb_set:set(), gb_tree:tree(), queue:queue(), sets:set(), and ets:tid() can be used. (Note: it has always been necessary to use ets:tid().) It is allowed in OTP 17.0 to locally re-define the types array(), dict(), and so on. New types array:array/1, dict:dict/2, gb_sets:set/1, gb_trees:tree/2, queue:queue/1, and sets:set/1 have been added.
2014-02-22Introduce parameterized opaque typesHans Bolinder
Handle immediate opaque types as aliases: A declaration of dict/0 -opaque dict() :: dict(_, _). -opaque dict(Key, Value) :: ... is handled as an alias, that is, when using dict() it is immediately replaced by dict(_, _). This is a means to avoid having to handle equivalent opaque types later. To be changed if it doesn't work well.
2014-02-22Fix a bug concerning parameterized typesHans Bolinder
This should fix a problem with variables in parameterized types. In particular it concerns parameterized opaque types and records.

2014-01-21[dialyzer] Re-work the handling of opaque typesHans Bolinder
It is now OK to inspect and modify the internals of opaque types within the scope of the module. The contracts are used for decorating types with opaqueness when it is harmless to do so. The opaqueness is propagated by the typesig module and also by the dataflow module. A lot of details have been fixed or updated. In particular the modules erl_types and erl_bif_types have been modified extensively. The version in vsn.mk has been updated to 2.7. The reason is a modification of #opaque{} in erl_types. Dialyzer seems to be about five percent slower than it used to be.
2013-10-09Fix crash when using remote types in the tail of list typesKostis Sagonas
Hans Bolider reported a dialyzer crash when using a remote type in the tail position of a maybe_improper_list() declaration. A test was created (by extending an existing module of the testsuite) and erl_types was modified to expand the remote type and not pass it unexpanded to subsequent phases in the processing.

2013-02-13Change the return value of hipe_bifs:remove_refs_from/1Kostis Sagonas
In order to avoid an ummatched return warning in erts and make the code more sane, the return value of the bif was changed from [] to 'ok'. (Probably more hipe_bifs need such changes but they will have to wait.) While at it, the code of various functions in hipe_unified_loader was shortened by using lists:foreach/1 instead of explicit recursion.

2013-01-25Extend char() to Unicode charactersHans Bolinder
The code related to the introduction of unicode_string() and unicode_char() has been removed. The types char() and string() have been extended to include Unicode characters. In fact char() was changed some time ago; this commit is about cleaning up the documentation and introduce better names for some functions.

The type ascii_string() in the base64 module has been corrected. The type file:file_info() has been cleaned up. The type file:fd() has been made opaque in the documentation. The type nodes() has been removed from erl_bif_types.erl.
