In Ada, an enum can contain character literals. GNAT encodes these
values in a special way. For example, the Unicode character U+0178
would be represented as 'QW0178' in the DWARF:
<3><112f>: Abbrev Number: 2 (DW_TAG_enumerator)
<1130> DW_AT_name : (indirect string, offset: 0x19ff): QW0178
<1134> DW_AT_const_value : 2
gdb handles this reasonably well, but failed to handle the 'QWW'
encoding, which is used for characters outside the base plane.
Also, while working on this, I noticed that gdb will print the decimal
value for an enum character constant:
(gdb) print Char_X
$2 = 1 'x'
This is a nice feature, IMO, because in this situation the 'x' enum
constant does not have its usual decimal value -- it has the value
that's assigned based on the enumeration type.
However, gdb did not do this when it decided to print the constant
using the bracket notation:
(gdb) print Char_Thorn
$3 = ["de"]
This patch changes gdb to print the decimal value here as well, and to
put the bracket notation in single quotes -- otherwise gdb will be
printing something that it can't then read. Now it looks like:
(gdb) print Char_Thorn
$3 = 4 '["de"]'
Note that gdb can't read longer bracket notations, like the other ones
printed in this test case:
(gdb) print Char_King
$4 = 3 '["01fa00"]'
While I think this is a bug, I plan to fix it separately.
Finally, in the new test case, the copyright dates are chosen this way
because this all started as a copy of an existing test.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
