2014-12-01compiler: Coalesce map keys in dialyzer modeBjörn-Egil Dahlberg
This fixes a regression introduced in commit 805f9c89fc01220bc1bb0f27e1b68fd4eca688ba The problem occured with map keys compiled with dialyzer option turned on. In OTP 17, map keys needs to be literals.

2014-10-27Extract annotations from filter qualifiers in a type-friendly wayBjörn Gustavsson
Commit 78ce8917d started to use get_anno/1 to extract the line annotation from filter qualifiers in comprehensions, but this does not respect the spec of this function and resuls in a dialyzer warning. To make the code more type-friendly, introduce a get_qual_anno/1 function. Kostis Sagonas suggested that the function should be implemented similar to this to also ensure that the qualifiers are of the appropriate form: get_qual_anno({call,Line,_,_}) -> Line; get_qual_anno({op,Line,_,_,_}) -> Line; . . . get_qual_anno({var,Line,_}) -> Line. The problem is that it is difficult to know exacly which forms that may occur and the function will need to be updated if new abstract forms are added. Thus this implementation would complicate maintanance without any real payoff. Reported-by: Kostis Sagonas

2014-09-01sys_core_fold: Eliminate name capture bugBjörn Gustavsson
The scope is supposed to contain all variables that are currently live. We need this information for certain optimizations to avoid capturing a name (a name that is in the scope must be renamed; for an example, see move_let_into_expr/2 or any function that calls sub_subst_scope/1). We also use the scope to optimize sub_del_var/2 and sub_is_val/2. When optimizing case expressions, the scope could be reset to an empty list (because sub_new/0 was called instead of sub_new/1). That could cause name capture if inlining was turned on. As simple way to force this bug is to uncomment the "-define(DEBUG, 1)." near the beginning of the file. Without this correction, most files in the test suite fail to compile.

2014-08-26compiler: Use expressions in core patternsBjörn-Egil Dahlberg
Two patterns, binary_segment size and map_pair key, are expressions even in matching. If only bound variables are used we are fine but some expressions which appears as literals needs to be lifted. Currently only Map key binaries will use this.

Unary ops are normalized before core transformation, i.e. handle negative integers as map keys. Strictly speaking, map keys are expressions but by handling them as patterns we can normalize negative integers.

2014-06-17[dialyzer] Fix handling of literal recordsHans Bolinder
This ticket is about records in Erlang code, and when to check the fields against the (optional) types given when defining records. Dialyzer operates on the Erlang Core format, where there are no trace of records. The fix implemented is a Real Hack: Given the new option 'dialyzer' erl_expand_records marks the line number of records in a way that is undone by v3_core, which in turn inserts annotations that can be recognized by Dialyzer.
