2015-09-09dialyzer: Correct the handling of parameters of opaque typesHans Bolinder
Prior to this commit, the fact that parameters of opaque types are expanded differently depending on the current values of limits used during expansion, caused problems later when the types of parameters are used for determining if opaque types are comparable.

2015-08-25dialyzer: Optimize expansion of parameters of opaque typesHans Bolinder
Opaque recursive parameters are expanded faster.
2015-08-25dialyzer: Optimize the expansion of parameterized types somewhatHans Bolinder
Expand parameters when needed only. The opaqueness is removed from types expanded to any().

2015-08-25dialyzer: Generalize an argument of erl_types:t_from_form()Hans Bolinder
Add more information about the caller of t_from_form(). Instead of just the module, also provide name of the type, spec, or record where the type form resides.

The example is provided by James Fish in http://erlang.org/pipermail/erlang-questions/2014-December/082204.html. Note that warnings with text such as "the _ variable breaks opaqueness" are still possible.
2015-07-11Teach Dialyzer arity of funs with literal arityLuca Favatella
Re-insert logic for `erlang:make_fun/3` in `erl_bif_types`. It had been removed in bd941f5 while type spec-ing `erlang.erl`. Type spec in `erlang.erl` cannot express arity of returned fun based on value of argument hence re-introducing logic in `erl_bif_types`. Re-definition of logic in `erl_bif_types` follows approach in 9d870a0.
2015-07-10ose: Remove all code related to the OSE portLukas Larsson
The OSE port is no longer supported and this commit removed it and any changes related to it. The things that were general improvements have been left in the code.

2015-06-15dialyzer: Fix a minor bug concerning opaque typesHans Bolinder
The test t_is_none() does not check for opaque types (and this is most likely how it should be), why t_opaque() should never be called with none().
2015-06-15dialyzer: Modify warning for comparison of opaque typesHans Bolinder
Comparing two operands for (in)equality is allowed if both operands are of the same unknown opaque type. Since OTP 17, there is a warning if the types of the operands have nothing in common (this cannot happen before OTP 17). However, the warning says there is a test between opaque types, which is wrong. The warning now states that the comparison cannot evaluate to 'true', which is more consistent.
2015-06-15dialyzer: Modify the handling of parametrized opaque typesHans Bolinder
In OTP 17 it is possible to mix types such as dict:dict() and dict:dict(_, _) outside of the dict module (and similarly for some other opaque types in STDLIB), but the results are unfortunately possibly invalid warnings in users' code. In OTP 18 parameterized opaque types with the same name but with different number of parameters are no longer compatible when seen from outside of the module where the types are declared. The types in STDLIB have been updated accordingly; for instance -opaque dict() :: dict(_, _). has been replaced by -type dict() :: dict(_, _).
2015-06-15dialyzer: Fix a bug in the expansion of formsHans Bolinder
The check that a modified type of a field is a subtype of the declared type has been moved outside of the expansion of forms to avoid loops.

2015-05-27Change hipe_bifs:system_crc/1 to hipe_bifs:system_crc/0Magnus Henoch
The macro HIPE_SYSTEM_CRC used to contain a hidden cookie from the VM that generated hipe_literals.hrl. This means that BEAM files containing that macro would be tied to a particular version of the VM. Change hipe_bifs:system_crc such that it doesn't require a hidden cookie to return the desired value.
2015-05-12Allow use of complete interface of cerl_pmatch moduleKostis Sagonas
The cerl_pmatch module performs pattern matching compilation at the level of Core Erlang. Functions that were not needed by the HiPE compiler were ifdef-ed out. However, these functions may come handy to other users; in particular a new testing tool currently under development needs access to these functions. While at it, added specs for these exported functions and also strengthened the spec of another one.

2014-06-17[dialyzer] Fix handling of literal recordsHans Bolinder
This ticket is about records in Erlang code, and when to check the fields against the (optional) types given when defining records. Dialyzer operates on the Erlang Core format, where there are no trace of records. The fix implemented is a Real Hack: Given the new option 'dialyzer' erl_expand_records marks the line number of records in a way that is undone by v3_core, which in turn inserts annotations that can be recognized by Dialyzer.

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.
