BOARD: clean naming of profiling data *.gcda

[Apaczer]

Otherwise it brakes MinGW git or be it WSL2 with native git - to long file names for Win FS.

welp the compiler ask for #home#runner#work#buildroot#buildroot#output#build#libretro-gpsp-092c5144827ee3ac07a6af9276244221c303ca41#<src_file>.gcda so need to find a workaround to explictly point to only <src_file>.gcda or maybe run prebuild script and change the naming on the run.

Anyway you can't use normally provided *.gcda data in current state because for e.g. when running locally on your machine, a working directory of compiler changes.

mm ive had similar problems with paths so i solved it by using git config --system core.longpaths true i wonder if this affects also files (or if there is a counterpart for files)

If you want directory structure intact in profile/ data output don't indicate path in -fprofile-generate.

or run this script for output .gcda files (replace <commit> with git hash):

for file in *; do cleanname=$(echo "$file" | sed 's/^.*<commit>#//') ; mv "$file" "$cleanname" ; done

for file in *; do newdirectory=$(echo "$file" | sed 's/#[^#]*$//' | sed 's/#/\//g') ; mkdir -p "$newdirectory" ; newname=$(echo "$file" | sed 's/^.*#//') ; mv "$file" "$newdirectory/$newname" ; done
