Fix lookup of separate debug file on MS-Windows.
If you put the separate debug file in a global debug directory, GDB on
MS-Windows would fail to find it. This happens because we obtain the
directory to look up the debug file by concatenating the debug
directory name with the leading directories of the executable, and the
latter includes the drive letter on MS-Windows. So we get an invalid
file name like
d:/usr/lib/debug/d:/usr/bin/foo.debug
This commit fixes that by removing the colon of the drive letter,
thus producing
d:/usr/lib/debug/d/usr/bin/foo.debug
gdb/ChangeLog:
2019-05-03 Eli Zaretskii <eliz@gnu.org>
* symfile.c (find_separate_debug_file): Remove colon from the
drive spec of DOS/Windows file names of the target, so that the
file name produced from DEBUGDIR and the target's directory will
be valid on DOS/Windows systems.
gdb/doc/ChangeLog:
2019-05-03 Eli Zaretskii <eliz@gnu.org>
* gdb.texinfo (Separate Debug Files): Document how the
subdirectory of the global debug directory is computed on
MS-Windows/MS-DOS.
