Well, the problem is that covoar in rtems-tools is hard-coded to use the QEMU
format, and the -f switch to change format is not used. I have attached a patch
to fix that. After that, covoar works fine with the coverage data from sis:
cat coverage/summary.txt
Bytes Analyzed : 20034
Bytes Not Executed : 11734
Percentage Executed : 41.43
Percentage Not Executed : 58.57
Uncovered ranges found : 242
Total branches found : 443
Uncovered branches found : 167
68 branches always taken
99 branches never taken
If you approve to the patch, then I will check it in (now that I know how ...
:-))
