2014-02-07compiler: Fix sys_core_fold let optimizationBjörn-Egil Dahlberg
Map variable was not covered and faulty optimization could occur. Ex. t() -> M0 = id(#{ "a" => 1 }), #{ "a" := _ } = M0, M0#{ "a" := b }. M0 was lost in let expression optimization.

2014-02-07compiler: Fix codegen multiple updates for MapsBjörn-Egil Dahlberg
This fixes an error on multiple updates optimization for map pairs. The error was introduced with moving to term order in Maps. This also fixes an error where register life time was lost for values and could result in erroneuos values being emitted in for map pairs. Simplified v3_codegen by moving multiple update optimizations to v3_kernel.

2014-02-05beam_bsm: Eliminate emulator crash when a binary is calledBjörn Gustavsson
We must not do the delayed binary creation optimization if the code attempts to call the matched out binary. Calling a matchstate will crash the run-time system. Reported-by: Loïc Hoguin
2014-02-05beam_validator: Validate the "fun" argument for a call_fun/1 instructionBjörn Gustavsson
The fun argument for a call_fun/1 instruction was not validated.

* bjorn/eep37/OTP-11537: Issue a warning when a named fun is constructed but not used
2014-02-04sys_core_fold: Prevent case expressions from being evaluated twiceBjörn Gustavsson
In e12b7d5331c58b41db06cadfa4af75b78b62a2b1, a bug was introduced that would cause case expressions to be evaluated more than once if there were aliases in the pattern. Example: X = Y = io:put_chars("some chars"), {X,Y} That would be rewritten to code similar to (but in Core Erlang): X = io:put_chars("some chars"), X = io:put_chars("some chars"), {X,Y} Make sure that we only evalute the expression once by doing a transformation similar to (but in Core Erlang): NewVar = io:put_chars("some chars"), X = NewVar, Y = NewVar, {X,Y} Reported-by: José Valim Reported-by: Anthony Ramine

2014-01-28compiler: Fix get_map_element bug with allocateBjörn-Egil Dahlberg
The instruction get_map_element has a faillabel so you may not use the instruction within a allocate/deallocate block.

2014-01-28sys_core_fold: Remove optimization that has become invalidBjörn Gustavsson
With the => and := operators for updating maps, this optimization is no longer valid.
2014-01-28compiler: Implement support for exact Op in MapsBjörn-Egil Dahlberg
The syntax is handled upto v3_kernel where it is reduced to previous behaviour for construction and updates. Meaning, the ':=' operator is handled exactly as '=>' operator.

Update erlang lint and syntax expand for #{ K := V }
2014-01-28erts: Add the type-testing guard BIF is_map/1Björn-Egil Dahlberg
To add a type-testing guard BIF, the following steps are needed: * The BIF itself is added to bif.tab (note that it should be declared using "ubif", not "bif"), and its implementation to erl_bif_op.c. * erl_internal must be modified in 3 places: The type test must be recognized as guard BIF, as a type test, and it must be auto-imported. * There must be an instruction that implements the same type test as the BIF (it will be used in guards). beam_utils:bif_to_test/3 must be updated to recognize the new guard BIF.
2014-01-28compiler: Fix sorted keys in put_map instructionBjörn-Egil Dahlberg
All pairs in a Map needs to be in strict ascending key order.
