* maint:
Fix miscompilation when module contains multiple named funs
Fix locations of shadowing warnings in ms_transform
|
|
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.

miscompiled.

Matching of type:
#{K := V1} = #{K := V2} = M,
Will alias (coalesce) to
#{K := V1 = V2} = M.

Need heap for maps is zero and fall through is also zero.

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.

Check for literals instead of variables when constructing chains.
|
|
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.

[dialyzer] Correct a doc bug introduced in 0b041238
[dialyzer] Use the option 'dialyzer' to control the compiler
[dialyzer] Fix handling of literal records
|
|
|
|
|
|
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.
