Sorry for the noise, but I have a better patch that actually solves the root problem. I ran the full testsuite on sis and covoar against libscore.a like this:

$ sparc-rtems5-ar -rcs sparc-rtems5/c/leon3/cpukit/score/libscore.a sparc-rtems5/c/leon3/cpukit/score/src/*.o

$ rtems-test --rtems-bsp=leon3-sis-cov sparc-rtems5/c/leon3/testsuites

$ /opt/rtems/5/share/rtems/tester/bin/covoar -v -f TSIM -S /opt/rtems/5/share/rtems/tester/rtems/testing/coverage/score-symbols.ini -O coverage -E /opt/rtems/5/share/rtems/tester/rtems/testing/coverage/Explanations.txt -p RTEMS-5  sparc-rtems5/c/leon3/testsuites/*/*.exe

All symbol sizes and ranges are now correctly reported/calculated in the reports. There are two remaining issues to be solved:

1. File names are printed as 'unknown' in reports (minor problem but useful)

2. We should add RISC-V support to covoar ...

Let me know if you agree to the patch ..
