Sure: I obviously care about Solaris (and IRIX and Tru64 UNIX :-), and even
a minimal hello.c fails the test:
r...@zingana 218 > cat hello.c
int
main (void)
{
return 0;
}
r...@zingana 219 > ./xgcc -B./ -g0 -c hello.c -o hello-g0.o
r...@zingana 220 > ./xgcc -B./ -g -c hello.c -o hello-g.o
r...@zingana 221 > /vol/gcc/src/gcc-dist/contrib/compare-debug --preserve
hello-g0.o hello-g.o
hello-g0.o.stripped. hello-g.o.stripped. differ: char 33, line 1
preserving hello-g0.o.stripped. hello-g.o.stripped.
r...@zingana 222 > ls -l hello*.o*
-rw-r--r-- 1 ro gcc 1964 Sep 2 18:23 hello-g.o
-rw-r--r-- 1 ro gcc 884 Sep 2 18:21 hello-g.o.stripped
-rw-r--r-- 1 ro gcc 884 Sep 2 18:23 hello-g.o.stripped.
-rw-r--r-- 1 ro gcc 630 Sep 2 18:23 hello-g0.o
-rw-r--r-- 1 ro gcc 630 Sep 2 18:21 hello-g0.o.stripped
-rw-r--r-- 1 ro gcc 630 Sep 2 18:23 hello-g0.o.stripped.
