2015-09-04compiler: Add test for corrupt register in get_map_elementsBjörn-Egil Dahlberg

2015-04-15Raise more descriptive error messages for failed map operationsBjörn Gustavsson
According to EEP-43 for maps, a 'badmap' exception should be generated when an attempt is made to update non-map term such as: <<>>#{a=>42} That was not implemented in the OTP 17. José Valim suggested that we should take the opportunity to improve the errors coming from map operations: http://erlang.org/pipermail/erlang-questions/2015-February/083588.html This commit implement better errors from map operations similar to his suggestion. When a map update operation (Map#{...}) or a BIF that expects a map is given a non-map term, the exception will be: {badmap,Term} This kind of exception is similar to the {badfun,Term} exception from operations that expect a fun. When a map operation requires a key that is not present in a map, the following exception will be raised: {badkey,Key} José Valim suggested that the exception should be {badkey,Key,Map}. We decided not to do that because the map could potentially be huge and cause problems if the error propagated through links to other processes. For BIFs, it could be argued that the exceptions could be simply 'badmap' and 'badkey', because the bad map and bad key can be found in the argument list for the BIF in the stack backtrace. However, for the map update operation (Map#{...}), the bad map or bad key will not be included in the stack backtrace, so that information must be included in the exception reason itself. For consistency, the BIFs should raise the same exceptions as update operation. If more than one key is missing, it is undefined which of keys that will be reported in the {badkey,Key} exception.

To be sure that the compiler and BEAM virtual machine correctly handles literals maps, we must test it.

2015-01-28core_pp: Correct printing of map literalsBjörn Gustavsson
A map key in a pattern would be incorrectly pretty-printed. As an example, the pattern in: x() -> #{ #{ a => 3 } := 42 } = X. would be pretty-printed as: <~{~<~{~<'a',3>}~,42>}~ instead of: <~{~<~{::<'a',3>}~,42>}~ When this problem has been corrected, the workaround for it in cerl:ann_c_map/3 can be removed. The workaround was not harmless, as it would cause the following map update to incorrectly succeed: (#{})#{a:=1}

Literal nil values aren't tagged tuple but the bare atom nil. The function lists:sort/2 expects the passed function to return true if the first element is less than or equal to the second, not strictly less than. The original base clause is changed accordingly. Reported-by: Ulf Norell
