cflow-1.7 released [stable]

[Sergey Poznyakoff]

Hello,

This is to inform you that GNU cflow release 1.7 is available for download.
See the end of this message for the list of noteworthy changes.

GNU cflow analyzes a collection of C source files and prints a graph,
charting control flow within the program.  It can produce both direct
and inverted flowgraphs in several output formats.

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify cflow-1.7.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver keyserver.ubuntu.com --recv-keys 3602B07F55D0C732

and rerun the 'gpg --verify' command.

New in this release:

* Multiple start functions are allowed

The '--main' option can be given multiple times.  A separate graph
will be drawn for each function given as its argument.

* New option --target=FUNCTION

If this option is given, the produced graph will contain only paths
leading from start function (or functions) to the given FUNCTION.

Multiple '--target' options are allowed.

* New output format: dot

The '-f dot' (or '--format=dot') option instructs cflow to output
graph as a description in DOT language, suitable as input to graphviz
programs.

* cflow-mode: new commands for navigating in the graph:

  c   go to the calling function
  n   go to the next function at the same nesting level
  p   go to the previous function at the same nesting level

* Bugfixes:

** CVE-2019-16165
** CVE-2019-16166
** Fix parsing of K&R style function declarations
** Improve parsing of typecasts
** Fix recursive call detection

Best regards,
Sergey
