I just found this report--seems to be still an issue in 12.1.

    gcc: honour -ffile-prefix-map in ASM_MAP [PR93371]

    -ffile-prefix-map is supposed to be a superset of -fmacro-prefix-map
    and -fdebug-prefix-map. However, when building .S or .s files, gas is
    not called with the appropriate --debug-prefix-map option when
    -ffile-prefix-map is used.

    While the user can specify -fdebug-prefix-map when building assembly
    files via gcc, it's more ergonomic to also support -ffile-prefix-map;
    especially since for .S files that could contain the __FILE__ macro,
    one would then also have to specify -fmacro-prefix-map.

    gcc:
            PR driver/93371
            * gcc.cc (ASM_MAP): Honour -ffile-prefix-map.

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
