2017-09-14Pack sequences of trailing 'f' operandsBjörn Gustavsson
Pack sequences of trailing 'f' operands for instructions such at jump_on_val or i_select_val_lins.
2017-09-14Implement packing of 'f' and 'j'Björn Gustavsson
2017-09-14Make sure that mask literals are 64 bitsBjörn Gustavsson
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.
2017-09-14Add information about offset to common group start positionBjörn Gustavsson
2017-09-14Remove JUMP_OFFSETBjörn Gustavsson
It has served its purpose.
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

2017-09-13erts: Fix 'on_load' tracing bug for modules with -on_loadSverker Eriksson
Symptom: VM crash when erlang:trace_pattern(on_load, ..) is set and module with -on_load is loaded. Problem: Tracing and -on_load clash in their use of Export.beam[1] Solution: Do not do call set_default_trace_pattern in finish_loading_1 for modules with -on_load. finish_after_on_load_2 will do that anyway.

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.

2017-09-13inets: httpd - Add chunk handling of client dataIngela Anderton Andin
If the client uses PUT or POST to send a HTTP body the server currently will gather the whole body in memory before passing it on to the mod-callback. For legacy reasons it also converts the binary body to a list, this is really bad for memory usage! Add new option max_client_body_chunk to enable chunked handling of content-length requests. Also make it possible for chunked-encoded data to be propagated in portions to the mod-callback. Conflicts: lib/inets/test/httpd_SUITE.erl

This commit removes the call to ets:safe_fixtable/2 introduced in commit 9458495. ETS memory can now be reclaimed while merging PLTs.
2017-09-12dialyzer: Adjust a test caseHans Bolinder
Huge maps are truncated differently by the pretty printer. The reason is that erl_types:is_singleton_type/1 no longer recognizes complex singleton types, which results in a less precise representation of map types.
2017-09-12dialyzer: Modify handling of singleton map key typesHans Bolinder
The test case loop.erl shows that there is a problem with certain singleton key types. Here the internal representation toggles between #{a | b => ...} and #{a => ..., b => ...} The choice is to turn #{a | b => ...} into #{a => ..., b => ...} early (t_from_form()). The aim is to keep as much info as possible (in pairs). However, including complex singleton keys (tuples, maps) in this scheme is potentially too costly, and a bit complicated. So one more choice is made: let atoms and number (and nothing else) be singleton types, and let complex keys go into the default key.
