[LTP] Finding True Application Code Coverage in case of heteregenous Executable Environment

[Subrata Modak <subrata@linux.vnet.ibm.com>]

Peter,

Is there a way to find true application code coverage for a
heterogeneous Executable Environment, where the application can consist
of:
     1. C Programs(only for which .gcno and .gcda files can be
        generated)
     2. Shell Scripts,
     3. Perl Scripts,
     4. Python Scripts,
     5. etc ?

Is there any by which i can also count the no. of lines/ branches/
Functions executed by the Scripts ??

Another question. when i tried to execute the following, it took into
consideration only the .gcda of the C executables invoked by the
program:
     1. lcov --directory /root/LTP-GIT/ltp/ --zerocounters
     2. (cd /opt/ltp/; ./runltp -f math)
     3. lcov --directory /root/LTP-GIT/ltp/ --capture --output-file
        app.info
     4. genhtml app.info

Instead i wanted it consider all C files for which .gcno are present
and .gcda are not present(as i did not execute the corresponding
binaries), so to truly find the exact % of C files covered and % left
out from the whole trickled down /root/LTP-GIT/ltp/ directory.
