strcmp (and unlike strcmp_iw), it returns negative if STRING1 <
|
|
|
|
|
STRING2, 0 if STRING2 = STRING2, and positive if STRING1 > STRING2
|

according to that ordering.
|

|
If a list is sorted according to this function and if you want to
|
|
|
|
|
find names in the list that match some fixed NAME according to
|
|
|
|
|
strcmp_iw(LIST_ELT, NAME), then the place to start looking is right
|
|
|
|
|
where this function would put NAME.
|
|
|
|
|
|
|
|
|
|
Here are some examples of why using strcmp to sort is a bad idea:
|
|
|
|
|
|
|
|
|
|
Whitespace example:
|
|
|
|
|
|
|
|
|
|
Say your partial symtab contains: "foo<char *>", "goo". Then, if
|
|
|
|
|
we try to do a search for "foo<char*>", strcmp will locate this
|
|
|
|
|
after "foo<char *>" and before "goo". Then lookup_partial_symbol
|
|
|
|
|
will start looking at strings beginning with "goo", and will never
|
|
|
|
|
see the correct match of "foo<char *>".
|
|
|
|
|
|
|
|
|
|
Parenthesis example:
|
|
|
|
|
|
|
|
|
|
In practice, this is less like to be an issue, but I'll give it a
|
|
|
|
|
shot. Let's assume that '$' is a legitimate character to occur in
|
|
|
|
|
symbols. (Which may well even be the case on some systems.) Then
|
|
|
|
|
say that the partial symbol table contains "foo$" and "foo(int)".
|
|
|
|
|
strcmp will put them in this order, since '$' < '('. Now, if the
|
|
|
|
|
user searches for "foo", then strcmp will sort "foo" before "foo$".
|
|
|
|
|
Then lookup_partial_symbol will notice that strcmp_iw("foo$",
|
|
|
|
|
"foo") is false, so it won't proceed to the actual match of
|
|
|
|
|
"foo(int)" with "foo". */

gdb/ChangeLog:
2003-01-23 Alexander Larsson <alexl@redhat.com>
Jim Blandy <jimb@redhat.com>
Add support for executables whose debug info has been separated
out into a separate file, leaving only a link behind.
* objfiles.h (struct objfile): New fields: separate_debug_objfile
and separate_debug_objfile_backlink.
(put_objfile_before): New declaration.
* symfile.c: #include "filenames.h".
(symbol_file_add_with_addrs_or_offsets): If this objfile has its
debug info in a separate file, read that, too. Save the addrs
argument, so we can use it again to read the separated debug info;
syms_from_objfile modifies the table we pass it.
(reread_symbols): After re-reading an objfile, call
reread_separate_symbols to refresh its separate debug info
objfile, if it has one.
(reread_separate_symbols, find_separate_debug_file,
get_debug_link_info, separate_debug_file_exists): New functions.
(debug_file_directory): New global var.
(_initialize_symfile): Initialize debug_file_directory, and
provide the new `set debug-file-directory' command to let the user
change it.
* objfiles.c (free_objfile): If this objfile has its debug info in
a separate objfile, free that one too. If this is itself a
separate debug info objfile, clear our parent's backlink.
(put_objfile_before): New function.
* utils.c (gnu_debuglink_crc32): New function.
* defs.h (gnu_debuglink_crc32): New declaration.
* Makefile.in (symfile.o): Note dependency on "filenames.h".
* configure.in: Handle --with-separate-debug-dir config option.
* acinclude.m4 (AC_DEFINE_DIR): New macro.
* acconfig.h (DEBUGDIR): New macro.
* configure, aclocal.m4, config.in: Regenerated.
gdb/doc/ChangeLog:
2003-01-23 Jim Blandy <jimb@redhat.com>
* gdb.texinfo (Separate Debug Files): New section.

gdb/ChangeLog:
2003-01-23 Alexander Larsson <alexl@redhat.com>
Jim Blandy <jimb@redhat.com>
Add support for executables whose debug info has been separated
out into a separate file, leaving only a link behind.
* objfiles.h (struct objfile): New fields: separate_debug_objfile
and separate_debug_objfile_backlink.
(put_objfile_before): New declaration.
* symfile.c: #include "filenames.h".
(symbol_file_add_with_addrs_or_offsets): If this objfile has its
debug info in a separate file, read that, too. Save the addrs
argument, so we can use it again to read the separated debug info;
syms_from_objfile modifies the table we pass it.
(reread_symbols): After re-reading an objfile, call
reread_separate_symbols to refresh its separate debug info
objfile, if it has one.
(reread_separate_symbols, find_separate_debug_file,
get_debug_link_info, separate_debug_file_exists): New functions.
(debug_file_directory): New global var.
(_initialize_symfile): Initialize debug_file_directory, and
provide the new `set debug-file-directory' command to let the user
change it.
* objfiles.c (free_objfile): If this objfile has its debug info in
a separate objfile, free that one too. If this is itself a
separate debug info objfile, clear our parent's backlink.
(put_objfile_before): New function.
* utils.c (gnu_debuglink_crc32): New function.
* defs.h (gnu_debuglink_crc32): New declaration.
* Makefile.in (symfile.o): Note dependency on "filenames.h".
* configure.in: Handle --with-separate-debug-dir config option.
* acinclude.m4 (AC_DEFINE_DIR): New macro.
* acconfig.h (DEBUGDIR): New macro.
* configure, aclocal.m4, config.in: Regenerated.
gdb/doc/ChangeLog:
2003-01-23 Jim Blandy <jimb@redhat.com>
* gdb.texinfo (Separate Debug Files): New section.
