Re: error while building leon3 with gcov flags

I suggest this because it is a work around for you. The long term solution could be to add the symbol to newlib's dummy RTEMS crt0.c, add it to librtemscpu.a (which is the temporary hack I suggested), add a libgcov.a implementation or stub to RTEMS, or modify GCC. Up until now, we have avoided

Re: error while building leon3 with gcov flags

For now, add a file to libcsupport/src which provides the symbols needed. Make sure things are methods or data as needed. Check GCC source for the prototype. On Sat, Jun 9, 2018, 3:34 PM Vijay Kumar Banerjee wrote: > On 10 June 2018 at 01:28, Joel Sherrill wrote: > >> >> >> On Sat, Jun 9,

Re: error while building leon3 with gcov flags

Hello, I was going through the gcc manual for gcov https://gcc.gnu.org/onlinedocs/gcc/Gcov-and-Optimization.html#Gcov-and-Optimization It mentions that the flag -fprofile-arcs is necessary for generating the .gcda files. I have tried it with a small hello world program to see the reports, and it

Re: error while building leon3 with gcov flags

Bringing in Krzysztof. Hoping he can get us on the right track here. I don't think you can run GcovData.cc independent of a covoar run. If you can figure out how to write a unit test that would be helpful. On Thu, Jun 7, 2018 at 2:29 PM, Vijay Kumar Banerjee < vijaykumar9...@gmail.com> wrote: >

Hello, I was looking into the code in GcovData.cc to see how it works and what it's doing, too me it looked like very messed up, I couldn't understand (yet) what it's trying to do. Is there some way I can manually run it for one file? Is there any place where I can read how it was intended to
