Last night I tried enabling coverage in boomerang compilation. It seems it will not be as easy as I thought. Gcov is failing to find source files, although the .gcda and .gcno files are being generated and are on the correct location. Snippet from gcov error:
$ gcov c/ansi-c-parser.gcda -o c -b >/dev/null
ansi-c.y:cannot open source file
/usr/local/lib/bison.cc:cannot open source file
ansi-c-parser.cpp:cannot open source file
In this case the source file is in c/ansi-c-parser.cpp, but it insists on looking for it in the current directory. For this specific case, I figured out the errors are due to #line directives generated by bison++, but there are various errors like this. I’ll look into them at another time. Currently, I’m investigating unexpected errors reported by the functional testsuite (more on this later).
