Changelog for fortran-src-0.3.0
0.3.0 (June 13, 2019)
- Add partial Fortran2003 support.
- Introduce datatype for BBGr instead of prior type alias for Gr.
- Now split into three fields: bbgrGr, bbgrEntries and bbgrExits
- May require refactoring of code to use bbgrGr field where a Gr was expected before.
- Introduce pragmaOffset field for Position, allowing pragmas to specify an apparent file and line-number.
- May require refactoring of code that uses the Position constructor.
- Fifth field is Maybe (Int, String), containing a line-offset and a target filename when present.
- It's designed such that most Position-based transformations are not affected by the pragmaOffset.
- They may need to preserve the field, though, as it passes through functions.
- Default value is 'Nothing'.
- Add --show-flows-to/--show-flows-from features
- Visualise the dataflow use/def chains using GraphViz.
- Add --show-block-numbers feature.
- Allows user to get AST-block numbers easily in order to use them with the above visualisation features.
- Fix several bugs with dataflow analysis that had accumulated.
- Eliminate StContinue and StEnddo are eliminated during GroupLabeledDo transformations.
- To be consistent with unlabeled Do.
- Parse and discard C-comments as a convenience feature for when fortran-src must interact with the output of C preprocessors that insert spurious comments.
- Add type propagation into type analysis, annotating every expression with a type.
- Additional interface: analyseTypesWithEnv to access a list of type errors found.
- Add dimensional information to CTArray and length/kind to TypeCharacter.
- Stricter checking of the grouping transform - if any statements that should be grouped are not grouped, raise an error.
- Support pragmas that alter the current 'filename and position' tracker, often used by preprocessors to help pinpoint original code locations.
- Uses a relative offset field called 'posPragmaOffset' so that relative measures continue to function correctly.
- Add constant propagation / parameter variable analysis.
- Add -c feature to compile 'fsmod files' with renaming and type info.
