handling of absolute source file paths


Hello,

considering http://sources.redhat.com/gdb/current/onlinedocs/gdb_8.html
, I expect the following behaviour:

$ mkdir /src /tmp/bin /tmp/src
$ cp /bin/ls /tmp/bin/zzz
$ gdb -q
(gdb) file /bin/zzz
/bin/zzz: Datei oder Verzeichnis nicht gefunden.
(gdb) dir /tmp
Source directories searched: /tmp:$cdir:$cwd
(gdb) file /bin/zzz
/bin/zzz: Datei oder Verzeichnis nicht gefunden.
(gdb) 

$ vi /src/a.c
$ gcc -g -o /tmp/bin/a /src/a.c
$ mv /src/a.c /tmp/src
$ gdb -q /tmp/bin/a
(gdb) l main
1       /src/a.c: Datei oder Verzeichnis nicht gefunden.
        in /src/a.c
(gdb) dir /tmp
Source directories searched: /tmp:$cdir:$cwd
(gdb) l main
1       main(){}

However, due to a change discussed in
http://sources.redhat.com/ml/gdb/2004-01/msg00243.html , gdb isn't able
to find the source even after the "directory" command; I consider this
to be a bug. We've implemented the change proposed in
http://sources.redhat.com/ml/gdb/2004-03/msg00026.html . The patched
version behaves the same for binaries, but finds the sources if the
"directory" command was issued.

I've run the test suite on an i386 platform. The only change was for
gdb.cp/annota2.exp from KFAIL to PASS, which is reported to "sometimes
fail unexpectedly" in PR gdb/544.

The patch applies also to the cvs head.

I suggest that it is included for stable and unstable branches. What do
you think?

I consider this patch to be not legally significant. Please inform me if
you need a copyright assignment.

ChangeLog entry:

	* defs.h:
	exec.c (exec_file_attach):
	nto-tdep.c (nto_find_and_open_solib):
	pa64solib.c (pa64_solib_sizeof_symbol_table):
	solib.c (solib_open):
	somsolib.c (som_solib_sizeof_symbol_table):
	source.c (is_regular_file, openp, open_source_file):
	symfile.c (symfile_bfd_open):
	wince.c (upload_to_device): Differentiate between the search for
	binary and source files.

With kind regards,
Baurjan.
