2017-03-16hipe: Add basic range splitting ra callbacksMagnus Lång
In addition to the temporary name rewriting that hipe_regalloc_prepass does, range splitters also need to be able to insert move instructions, as well as inserting new basic blocks in the control flow graph. The following four callbacks are added for that purpose: * Target:mk_move(Src, Dst, Context) Returns a move instruction from the temporary (not just register number) Src to Dst. * Target:mk_goto(Label, Context) Returns a unconditional control flow instruction that branches to the label with name Label. * Target:redirect_jmp(Instr, ToOld, ToNew, Context) Modifies the control flow instruction Instr so that any control flow that would go to a label with name ToOld instead goes to the label with name ToNew. * Target:new_label(Context) Returns a fresh label name that does not belong to any existing block in the current function, and is to be used to create a new basic block in the control flow graph by calling Target:update_bb/4 with this new name.
2017-03-16hipe: Add basic_edge_cases test caseMagnus Lång
Two tests are added, primarily aimed at the range splitters. * test_float_spills, which exercises the rare case of high floating point register pressure, including spill slot move coalescing. * test_infinite_loops, which tests that various infinite loops are properly compiled and do contain reduction tests (otherwise they would permanently hog their scheduler and not notice being sent an exit signal).

With this change, both the matches and does not match cases have fastpaths that does not need to call primops.
2017-02-28dialyzer: Improve a warningHans Bolinder
When a pattern a type do not match, opaque warnings were given precedence before structure mismatches. This is no longer always the case. Mentioned by Nick Marino on erlang-questions.

2017-02-03dialyzer: Do not keep the code server's type info on the heapHans Bolinder
The table used during translation of forms to types used to be a dictionary of the type info (-type(), -opaque(), and -record()) for all modules. Now it is reduced to the modules that are needed to handle references to types in other modules. The PLT:s type info is still kept on the heap.

2017-01-10dialyzer: Fix check of parameterized opaque typesHans Bolinder
Two parameters used to be "compatible" if one is a specialization of the other, in the way that the input type of t_limit() is a specialization of the output type. This check is now relaxed: any() in any of the two parameters is compatible with any type of the other parameter. The change is due to bugus warnings. A clause for maps has been added.
2016-12-21stdlib: Allow characters in types and constant patternsHans Bolinder
Characters ($char) can be used in constant pattern expressions. They can also be used in types and contracts.
