PR 27614 shows that gdb-add-index fails to generate the index when its
argument is a symlink.
The following one liner illustrates the reported problem:
$ echo 'int main(){}'|gcc -g -x c -;ln -s a.out symlink;gdb-add-index symlink
gdb-add-index: No index was created for symlink
gdb-add-index: [Was there no debuginfo? Was there already an index?]
$ ls -l
-rwxr-xr-x 1 25712 Mar 19 23:05 a.out*
-rw------- 1 8277 Mar 19 23:05 a.out.gdb-index
lrwxrwxrwx 1 5 Mar 19 23:05 symlink -> a.out*
GDB generates the .gdb-index file with a name that matches the name of
the actual program (a.out.gdb-index here), not the symlink that
references it. The remaining of the script is looking for a file named
after the provided argument (would be 'symlink.gdb-index' in our
example).
gdb/ChangeLog:
PR gdb/27614
* contrib/gdb-add-index.sh: Fix when called with a symlink as an
argument.
gdb/testsuite/ChangeLog:
PR gdb/27614
* gdb.dwarf2/gdb-add-index-symlink.exp: New test.
