2018-01-19ErLLVM: Preserve precise BEAM tailcall semanticsMagnus Lång
The BEAM compiler chooses not to perform tailcall optimisations for some calls in tail position, for example to some built-in functions. However, when the ErLLVM HiPE backend is used, LLVM may choose to perform tailcall optimisation on these calls, breaking the expected semantics. To preserve the precise semantics exhibited by BEAM, the 'notail' marker, present in LLVM since version 3.8, is added to call instructions that BEAM has not turned into tail calls, which inhibits LLVM from performing tail-call optimisation in turn.

Also modified erl_bif_types:infinity_bsl() when called with zero as first argument. As of writing this, erlang:'bsl'/2 is modified on the master branch to never fail if called with a huge second argument.

2017-11-22dialyzer: Extend the map implementation's handling of ?unitHans Bolinder
The Maps implementation handles ?unit in more cases. Exactly when t_is_none_or_unit() is to be called is not clear to me. The added cases are about a map type being ?unit, but the key or the value of an association can also be ?unit, but that is not always checked.

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.
2017-09-12dialyzer: 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.
