Add support for relaxed datatype model for array datatypes. 2014-11-16, by mjsousa
fix bug introduced a few commits ago: do not print the first char ('%') of a direct_variable_c (e.g. skip % in %IW4.2) 2014-11-09, 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

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
Initialise REF_TO variables to NULL. 2014-08-09, by mjsousa
Make support for REF_TO ANY a command line option. 2014-08-09, by mjsousa
Add support for non standard REF_TO ANY (equivalent to void *) 2014-08-09, 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
Add support for implicitly declared REF_TO datatypes. 2014-07-21, 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

array_specification_c may be used as a datatype! Add it to spec_init_separator_c 2014-07-20, by mjsousa
Change REF() operator to return the correct REF_TO datatype datatype. 2014-07-13, by mjsousa
Narrow array subscripts correctly, even in the presence of other datatype errors (so we do not generate error messages for array subscripts that do not contain errors). 2014-07-13, by mjsousa
Add support for REF_TO derived datatypes (along with datatype verification) 2014-07-13, by mjsousa

Remove un-used parameter from class constructor. 2014-07-06, by mjsousa
Move standard FBs to a pre-converted C file, insted of converting them every time along with the IEC source. 2014-07-06, by mjsousa
Move library files compiled to C to their own subdiectory. 2014-07-06, by mjsousa
Fix stupid mistake in previous commit (use 'long double' instead of 'ld' in istandard library macro) 2014-07-06, by mjsousa
merge 2014-07-05, by mjsousa
Update build/compile instructions to reflect the fact that autoconf needs to be executed. 2014-07-05, by mjsousa

closed temporary fix branch 2014-05-28, by Edouard Tisserant
