The assertion
gdb_assert (nr_bits >= 1 && nr_bits <= type_bitsize);
is not correct. Well, it's correct in that we do want the number of
bits to be in the range [1, type_bitsize]. But we don't check anywhere
that the end of the specified flag is within the containing type.
The following code should generate a failed assertion, as the flag goes
past the 32 bits of the underlying type, but it's currently not caught:
static void
test_print_flag (gdbarch *arch)
{
type *flags_type = arch_flags_type (arch, "test_type", 32);
type *field_type = builtin_type (arch)->builtin_uint32;
append_flags_type_field (flags_type, 31, 2, field_type, "invalid");
}
(You can test this by registering it as a selftest using
selftests::register_test_foreach_arc and running.)
Change the assertion to verify that the end bit is within the range of
the underlying type. This implicitly verifies that nr_bits is not
too big as well, so we don't need a separate assertion for that.

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.
