This reverts commit 07293be448, as it
causes an unintended change of behavior with GDB/MI's =library-loaded
events: The host-name="<path>" part of the event is now showing the
target-side path instead of the host-side path.
This revert affects Darwin and AIX systems, however, where the BFD
is either artificial or icomplete, leading to the outputt of
"info shared" not containing the information we'd like. For instance,
on Darwin, we would see:
(top-gdb) info shared
From To Syms Read Shared Object Library
0x00007fff8d060de4 0x00007fff8d09ce1f Yes (*) i386:x86-64
0x00007fff8af08b10 0x00007fff8b1c6f73 Yes (*) i386:x86-64
To compensate for that, we overwrite the filename of the associated bfd.
gdb/ChangeLog:
Revert the following commit:
* solib.c (solib_map_sections): Remove code overwriting
SO->SO_NAME with the bfd's filename.
Make the following changes required after the revert above:
* solib-aix.c (solib_aix_bfd_open): Set the filename of the
returned bfd to a copy of the synthetic pathname.
* solib-darwin.c (darwin_bfd_open): Set the filename of the
returned bfd to a copy of PATHNAME.
This removes gdb_string.h. This patch is purely mechanical. I
created it by running the two commands:
git rm common/gdb_string.h
perl -pi -e's/"gdb_string.h"/<string.h>/;' *.[chyl] */*.[chyl]

I tried debugging a remote Windows program on Linux host, and pointed the
sysroot to "/some/path/" rather than "remote:", and I found GDB couldn't
find the dlls in the sysroot. If the dll name is
"C:/Windows/system32/ntdll.dll", I end up with the sysroot+in_pathname
concatenated this way:
(top-gdb) p temp_pathname
$1 = 0x228b690 "/some/pathC:/Windows/system32/ntdll.dll"
^^
That is, a directory separator is missing. This is a regression.
The problem is that solib_find decides that since the target path has
a drive spec, a separator is not necessary, which is clearly wrong in
this case. That check was added in
<https://sourceware.org/ml/gdb-patches/2013-06/msg00028.html>, to
handle the case of sysroot being "remote:". This patch fixes that
original issue in a different way. Instead of checking whether the
path has a drive spec, check whether the sysroot is "remote:". The
patch adds a table that helps visualize the cases that need a
separator. I also confirmed the original issue is still handled as
expected. That is, that "set sysroot remote:" still does the right
thing.
remote_filename_p returns true if the filename is prefixed with
"remote:". In this case, we need to check whether the filename is
exactly "remote:". I thought of different ways or either changing
remote_filename_p or adding another convenience function to remote.c
to avoid exposing the "remote:" prefix out of remote.c. But all
attempts turned out adding lot of over needless complication. So the
patch just exposes the prefix behind a new macro, which allows using a
straighforward strcmp.
