It is an in-house airborne RTOS we develop in ISP RAS. There is a legacy paper
in English telling a bit more about the project

While true, this scenario is simply inconvenient in many cases.
(1) When filesystem path limitations exist, they will unavoidably lead to being
unable to save data due to extra large resulting paths. To remind yo

Path length limitation in the current case is 200 bytes, but in general the
issue is that we would like _to be able to properly set the gcda path for the
target_. Currently the specified path may not even exist wh

Sure, the example is published on godbolt, but for completeness:
int main() {}
gcc -fprofile-arcs -S t.c -o t.s
cat t.s | grep gcda
Adding the mentioned arguments (e.g. -fprofile-prefix-map=/home/user=/test)
