2016-05-04dialyzer: Use maps instead of dictHans Bolinder
Optimization: A few dictionaries are maps instead of dicts.
2016-05-03One more test suite for binary pattern matchingKostis Sagonas
Taken from the OTP test suites and changed accordingly for HiPE. Used to be problematic in the tests that matched against a segment of 'bad_size'. This was corrected in the BEAM compiler for OTP 19.
2016-04-29dialyzer: Fix a bug in the translation of forms to typesHans Bolinder
A bug is fixed, but there are more problems. Modify erl_types.erl like this: -define(EXPAND_LIMIT, 500). and bogus warnings are output (again). Callbacks and specs are compared (subtype) in dialyzer_behaviour. If they are expanded to different depths, then invalid warnings can be generated.

2016-04-28erl_types: Don't consider opaque keys singletonMagnus Lång
Opaque singleton keys have the unfortunate property, unlike any other singleton type, to overlap with other singleton types that do not have the same internal representation. Therefore, we must not keep opaque singletons in the Pairs list in a map type.
2016-04-28erl_types: Fix t_subtract/2 correctness bugMagnus Lång
t_subtract/2 would break its postcondition by always returning the underapproximation none() when given a variable on the right hand side. This broke map type parsing, since it relied on t_subtract/2 to tell it when map keys would shadow each other.
2016-04-28erl_types: Fix crash merging maps with opaque keysMagnus Lång
Opaque keys in maps broke an assumption in erl_types:mapmerge_otherv/3 (that the infinimum of a singleton type and some other type would either be none() or that same singleton type), causing a case_clause crash.

2016-04-28erl_types: Add a map type representationMagnus Lång
The type of a map is represented as a three-tuple {Pairs, DefaultKey, DefaultValue}. DefaultKey and DefaultValue are types. Pairs is a list of three-tuples {Key, mandatory | optional, Value}, where Key and Value are types. All types Key must be singleton, or "known at compile time," as the EEP put it. Examples: #{integer()=>list()} {[], integer(), list()} #{a=>char(), b=>atom()} {[{a, optional, char()}, {b, optional, atom()}], none(), none()} map() {[], any(), any()} A more formal description of the representation and its invariants can be found in erl_types.erl Special thanks to Daniel S. McCain (@dsmccain) that co-authored a very early version of this with me back in April 2014, although only the singleton type logic remains from that version.

2016-03-02hipe: Fix crashing bugs when inlining FP opsMagnus Lång
It was assumed in hipe_icode_fp:filter_map/3 that either all predecessors would have an up-to-date ("assigned") tagged copy, or none of them. This is temporarily false during the fixpoint loop in basic_floats:test_icode_type_crash_2/0, which exercises the all_args_equal(Bindings) =:= true branch, that would previously erroneously end up in the 'false' branch, which is what caused the crash in that case. This is likewise only temporarily false during the fixpoint loop in basic_floats:test_icode_type_crash/0, but that case instead exercises the 'false' branch, justifying the inclusion of both tests.

2015-12-16Fix compilation of matching with UTF binariesKostis Sagonas
The code generated by the HiPE compiler for pattern matching with UTF binaries was such that sometimes THE_NON_VALUE was stored in the roots followed by the garbage collector. This was not an issue for the vanilla native code compiler, but was problematic for the ErLLVM back-end. Fix the issue by not storing THE_NON_VALUE in the live roots. An alternative fix would be to change the code of the garbage collector. With this fix, there are no more (known) failing test cases for the ErLLVM back-end (at least on x86_64 with LLVM 3.5, which is the configuation regularly tested). Thanks to @margnus1 for the fix.
