Other Additions/Improvements
·
A new
statistics option, -A (/ASSESS), provides sorted list of procedure names,
lengths, and cyclomatic complexities v(G), output in
the summary/statistics section
·
Complete MPI
interface definition using stubs for thorough interface analysis and variable tracking
(see section 9.2 for stub information)

·
Force –O+
processing. Example: --w no longer supersedes –O+103
(warning: dead code).
·
Flint now exits
immediately if source is >72 columns but no –e was specified, which
generated a lot of spurious messages

Some messages
downgraded to FYIs if analysis performed in local mode (i.e., no –g): #136, 538
·
New xref legend
item, ‘C’ for “assoCiated”
·
A new command line
switch -o "message_format"
to change the format of Flint’s analysis messages, suitable for interfacing to
IDE/ editor such as Visual Studio

User Interface Changes to Note
·
Separator for cross
reference (xref) content selection is now ‘.’ instead of ‘_’; see Section 8.4 of flintman.pdf. Prior versions of Flint retain the old
syntax.
