With -Op option --> Place implicitly defined datatypes in the .h file corresponding to the POU where they are used.

Add name of POU as prefix to names of implicitly defined datatypes

Implicitly defined array datatypes use new naming method (greatly simplifies stage 4 code).

array_specification_c may be used as a datatype! Add it to spec_init_separator_c

Change REF() operator to return the correct REF_TO datatype datatype.

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).

Add support for REF_TO derived datatypes (along with datatype verification)

Add option to place each POU in a distinct .c and .h file pair.

code re-organisation. Preparing for the changes to come in the next commit (one C file for each POU)

Remove un-used parameter from class constructor.

Move standard FBs to a pre-converted C file, insted of converting them every time along with the IEC source.

Move library files compiled to C to their own subdiectory.

Fix stupid mistake in previous commit (use 'long double' instead of 'ld' in istandard library macro)

merge

Update build/compile instructions to reflect the fact that autoconf needs to be executed.

Fix time conversion function in std library, and change into macro (so it may be used in variable initialisations)

Add support for the stepname.T syntax.

Change the name of the variable with the step state to stepname.X (in the generated VARIABLES.csv file)

Add support for Stepname.X syntax.

Remove dead code previously left in by mistake.

Add error message for invalid datatype of transition condition. Generalize datatype narrowing algorithm for transition conditions.

merge

closed temporary fix branch

Check VAR_EXTERN variables declared in FBs instantiated in a Program (and recursively too - FBs in FBs).

Fix typo in as yet dormant code (related to REF_TO keyword, that is not yet active)

Fix compilation error on platforms where real64_t is mapped onto 'long double'

Correctly handle structured variables that include FB and external FBs (example: FB1.FB2.extFB3.FB4.extFB5.extFB6.structvar.field1 := 42;) (this commit fixes only ST code. TODO: IL and SFC)

Remove call to type_is_complex() in ST code generation.

A little code cleanup (reduce number of possible variable generation states)

Finish: Change order of SET_xxx() macros. (this will allow me to simplify the print_setter() methods later on)

Change order of SET_xxx() macros. (this will allow me to simplify the print_setter() methods later on)

More static declarations in POUS.c in order to avoid conflicting symbol definitions with new POUS.c inclusion scheme

Fix multiple resources support, POUS.c now only contain static definitions. POUS.c is included in configuration C code as well as in resources to allow GLOBAL FBs to be declared in configurations

Disable stage4 options with on windows since getsuboptr isn't supported in mingw

merge

Track of line number correctly when input file has code with very long lines.

Fix memory leak in lexical parser.

Make generation of #line directives optional.

Insert #line directives in generated C code.

Add support for parsing of REF_TO keyword (defined in IEC61131-3 v3). This support is currently inactive (in flex) until we get to add C code generation later on.

Update files to be ignored by mercurial: ignore files generated by autoconf, directory test/, and *.orig

Fix bug: do not print IL 'label' when generating inline functions (JMPxx label was generating erroneous C code)

Add limited support for the REF() operator (defined in v3 of IEC 61131-3)

Remove assertion being failed by IL labels (IL labels do not yet have specific datatypes).

Added stage1_2/Makefile.am weird rule to keep compatible with previous version of automake

Merge

fix definition of pragma.

Fix the state machine that became broken 2 commits ago (when adding support for nested comments)
