2017-09-15dialyzer: Improve check of unknown typesHans Bolinder
The implementation of OTP-14218 (commit 6d3b38a) has a weakness: only a very limited part of the type form is checked. This is now fixed: types not used by specs are checked equally well as types used by specs. The new function erl_types:t_from_form_check_remote() checks usage of remote types. It does not expand used local types, and has (almost) no limits on depth and size.

2017-09-14Add compile_info option to compileJosé Valim
This allows compilers built on top of the compile module to attach external compilation metadata to the compile_info chunk. For example, Erlang uses this chunk to store the compiler version. Elixir and LFE may augment this by also adding their own compiler versions, which can be useful when debugging. The deterministic option does not affect the user supplied compile_info. It is therefore the responsibility of external compilers to guarantee any added information does not violate the determinsitic option, if such option is supported. Finally, this code moves the building of the compile_info options to the compile module instead of beam_asm, moving all of the option mangling code to a single place.

2017-09-14Optimize i_select_tuple_arity2 and is_select_linsBjörn Gustavsson
Don't save a pointer to the default failure label. That could relieve register pressure. Instead, if we'll need to signal an error in i_select_tuple_arity2, delay to the execution phase. That should be a clear win because i_select_tuple_arity2 very rarely fails because of the term being selected is not a tuple.

Use the "ull" suffix for the mask literals instead of "ul" to ensure that the literals are 64 bits also on Windows.
2017-09-14Use relative failure labelsBjörn Gustavsson
Relative failure in itself is not an optimization, but we plan to pack failure labels in the future to save memory.

2017-09-14Document that the compiler may optimize away atomsBjörn Gustavsson
The following code could fail in the call to list_existing_atom/1: String = atom_to_list(some_atom), Atom = list_to_existing_atom(String) because the compiler will rewrite the code to: String = "some_atom", Atom = list_to_existing_atom(String) If some_atom is not used in another place, it will not exist. The compiler could be updated to preserve the atom in this simple case, but it would be hard to make sure that the compiler never loses atoms that exist in the source text. It also difficult to imagine a real world use case where this would be a problem. If an atom is mentioned only in a way that the compiler can optimize away, is there really any need to create the atom at all in list_to_existing_atom/1? Therefore, it is better to place the responsibility that the atom exists on the user of list_to_existing_atom/1. Update the documentation to mention that the compiler may optimize away atoms. https://bugs.erlang.org/browse/ERL-453

2017-09-13Refactor instructions to support relative jumpsBjörn Gustavsson
Introduce new macros that can be used for relative jumps and use them consistently. Test that everything works by using a non-zero constant JUMP_OFFSET. The loader subtracts JUMP_OFFSET from loaded labels, and all instructions that use 'f' operands add it back.
