@magicus now i've done a build without using -fdebug-prefix-map, and the 
debuginfo obviously contains lots of absolute paths to the "src" cpp/c/hpp/.. 
files, HOWEVER, if I grep for ".o" file names, I still only get the 3 hotspot 
assembly objects:

andrew@andrew:~$ strings 
/home/andrew2/jdk/build/linux-aarch64-server-release/images/jdk/lib/server/libjvm.debuginfo
 | grep andrew | grep ".o"
