Hello,
I added a back port of the gcov-tool merge-stream patches to GCC 12. You find
some background information here:
https://gcc.gnu.org/onlinedocs/gcc/Freestanding-Environments.html#Freestanding-Environments
A back port to GCC 10 would be quite difficult since the gcov file handling
changed significantly between GCC 10 and 12.
There is some work in progress to support MC/DC code coverage in gcov:
https://gcc.gnu.org/pipermail/gcc-patches/2022-March/592065.html
Back porting this to GCC 12 would be probably feasible.
It would be nice if we could make the gcov support available for RTEMS 6, but
this is only possible with an update to GCC 12. Are there any objections to
update the RSB to use the upcoming GCC 12 release for RTEMS 6?
Are there any posted test results?
I did only local test runs on simulators so far.
How do I build gcc12 with rtems6 and test? I am working on a large complex C++
framework with rtems6/gcc10 and it is working well and is stable. If there is a
way I can test what I am working on with gcc12 to determine if there are any
regressions that would help me decide.
I updated the RTEMS 7 tools to use the GCC 12 release branch with a gcov
back port. You can test GCC 12 with a local patch for RTEMS 6:
