Test case:
Let's consider having file "empty.S" with following contents:
// -- cut --
.text
ret
// -- cut --
$ gcc -c -o empty.S.o empty.S -O2 -g && strings -f empty.S.o | grep -F ${PWD}
&& echo NOT OK || echo OK
empty.S.o: /home/krd/gcc-prefix-case
empty.S.o: /home/krd/gcc-prefix-case
NOT OK
$ gcc -c -o empty.S.o empty.S -O2 -g -fdebug-prefix-map=${PWD}=. && strings -f
empty.S.o | grep -F ${PWD} && echo NOT OK || echo OK
OK
$ gcc -c -o empty.S.o empty.S -O2 -g -ffile-prefix-map=${PWD}=. && strings -f
empty.S.o | grep -F ${PWD} && echo NOT OK || echo OK
empty.S.o: /home/krd/gcc-prefix-case
empty.S.o: /home/krd/gcc-prefix-case
NOT OK
$ gcc -c -o empty.S.o empty.S -O2 -g -ffile-prefix-map=${PWD}=.
-Wa,--debug-prefix-map,${PWD}=. && strings -f empty.S.o | grep -F ${PWD} &&
echo NOT OK || echo OK
OK
