Sure. I used C-Vise:
https://github.com/marxin/cvise

with a built cross compiler:
cvise -c 'cp ~/Programming/gcc2/objdir/gcc/predict.gcda . &&
/home/marxin/Programming/gcc2/objdir/gcc/xgcc -B
/home/marxin/Programming/gcc2/objdir/gcc/ -fprofile-use -fselective-scheduling
-fselective-scheduling2 -fsel-sched-pipelining -g  -O3 -fno-strict-aliasing -c
predict.i 2>&1 | grep code_motion_process_successors' predict.i

Note that one can theoretically reduce also the .gcda file. I have an
experimental pass for it in C-Vise and I will likely upstream it.

Does it explain all your questions?
