Fix bugs introduced in previous commit (once again do constant folding of all literals in type declarations) 2014-12-14, by mjsousa

fix code generation when dereferencing pointers (ref_to) to arrays (ref_to_array^[5]) 2014-10-25, by mjsousa
Fix bug: set the scope annotation in deref_operators used inside structs 2014-10-25, by mjsousa
Editing of error message to make it more clear. 2014-10-25, by mjsousa
Filling of symbol->scope annotation moved from narrow to fill_candidate_datatypes_c (became possible because narrowing of struct, array and symbolic variables is now done directly in fill_candidate_datatypes_c) 2014-10-25, by mjsousa
fill_candidate_datatypes_c now uses search_varinstance_decl_c instead of search_varfb_instance_type_c (moving towards deprecation of search_varfb_instance_type_c) 2014-10-25, by mjsousa
Do the full fill_candidate/narrow_datatype algorithm for all fields of a structured variable in the fill_candidate_datatypes_c 2014-10-19, by mjsousa
Fix bug with multple dereferencing (bool_var := bool_ptr_ptr^^;) 2014-10-19, by mjsousa
Fix bug: Add support for de-referencing pointers to struct (struct_ptr^.elem1) when used inside FB. 2014-10-19, by mjsousa

Turn support of derefencing operator '^' an option (default is not supported). 2014-09-28, by mjsousa

Add support for REF_TO inside arrays and structs (a non-standard feature!) 2014-09-27, by mjsousa

Fix typos in comments 2014-08-11, by mjsousa
Add comments, and make get_datatype_id_str_c equivalent to get_datatype_id_c 2014-08-11, by mjsousa
Fix calling of functions whose parameters are of an implicitly declared datatype (currently only makes sense for REF_TO datatypes, but may make sense to other datatypes too if the datatype model is changed in the future). 2014-08-11, by mjsousa
fix indentations. 2014-08-10, by mjsousa
in lvalue, add check for REF() fucntion invocation, and the NULL literal 2014-08-10, by mjsousa

Update some comments. (No changes to code) 2014-08-08, by mjsousa
Introduce absyntax class for keyword ANY, and use REF_TO(ANY) as datatype of NULL literal. 2014-08-08, by mjsousa
Fix bug (introduced a few commits ago) when generating SFC actions that are mapped onto variables --> Make generate_sfcdecl_c stateless (i.e. does not depend on order by which it is called). 2014-08-06, by mjsousa
Add support for the 'NULL' keyword, defined in version 3 of IEC 61131-3. 2014-07-31, by mjsousa
for option '-Op' (generate <pouname>.h/c): add '#include <pouname>.h' to the .c file, and '#ifdef <pouname>_H' to the .h file 2014-07-29, by mjsousa
Ass include of iec_std_lib.h in POUS.h file. 2014-07-25, by mjsousa

With -Op option --> Place implicitly defined datatypes in the .h file corresponding to the POU where they are used. 2014-07-20, by mjsousa
Add name of POU as prefix to names of implicitly defined datatypes 2014-07-20, by mjsousa
Implicitly defined array datatypes use new naming method (greatly simplifies stage 4 code). 2014-07-20, by mjsousa
array_specification_c may be used as a datatype! Add it to spec_init_separator_c 2014-07-20, by mjsousa
