Generating coverage report with rtems-test

[Jerzy J]

Hi,

I'm still trying to generate coverage reports with RTEMS 6 and
gr712rc/leon3 bsps using rtems-test.

However I get a weird behaviour when coverage is generated.
The command I use:
`./rtems-test --rtems-tools=$HOME/RTEMS/rtems/6 --log=log_leon3_sis
--rtems-bsp=leon3-sis-cov --coverage
~/RTEMS/src/rtems/build/sparc/gr712rc/testsuites/validation/ts-model-barrier-mgr-0.exe`

In the log file generated i can see that tests pass, but after that I get:
`Running coverage analysis

Objdump error in generating objdump
Coverage time: 0:00:00.925464
Coverage generating reports
Coverage analysis finished: /home/yoman/RTEMS/rtems/6/bin`

In the generated report everything is at 100% coverage, but it just
contains unreferenced symbols and 0's otherwise. Branch and other reports
are empty.
I checked and it's same when SMP is enabled or disabled, as well as when
trying other tests. In fact it seems I have exactly same issue with any
test I try, even hello.exe.

Any suggestions as to how to fix it?

Thank you in advance and all the best!
