I am using gcc as a cross compiler (386-linux to powerpc-eabi) to generate code for an embedded power pc app. There is no operating system running on the target and I am using newlib instead of glibc, but I would still like to do code coverage analysis. Adding -ftest-coverage to the compile options generates the necessary .bb and .bbg files. Adding -fprofile-arcs causes the output code to contain space for the counts and each basic block has the necessary instructions for properly incrementing the counts. Of course, this doesn't work because I get a few unresolved symbols like "__bb_init_func" My target doesn't have a filesystem so there is no way to write the .da files. What I would like to do is supply my own library of functions to support -fprofile-arcs so the counts still end up being generated correctly in memory. I can then send the .da files over a serial port back to the host or use the gdb remote protocol to retrieve then and run gcov. I tried to figure out how to do this by looking at the assembly and map files generated for a simple program using the native compiler (running RedHat 7.1). However, I am having a hard time figuring out what functions I need to supply and what they should do. I found some of it in the gcc source code but there aren't many comments. Is there some documentation of how this works somewhere? Can somebody help me figure it out? thanks, marc ------ Want more information?
