I came across some code in buildsym_compunit::make_blockvector that uses
hardcoded constants 0 and 1:
...
gdb_assert (blockvector->block (0)->is_global_block ());
gdb_assert (blockvector->block (1)->is_static_block ());
...
Fix this by instead using the symbolic constants GLOBAL_BLOCK and
STATIC_BLOCK.
The same function has an odd-looking for loop that uses a hard-coded '1' to
skip the global block:
...
/* The 'J > 1' here is so that we don't place the global block into
the map. For CU with gaps, the static block will reflect the
gaps, while the global block will just reflect the full extent of
the range. */
for (int j = num_blocks; j > 1; )
{
--j;
struct block *b = blockvector->block (j);
...
Fix this by rewriting it into an ordinary descending for loop, and using
symbolic constant GLOBAL_BLOCK to avoid the global block:
...
for (int j = num_blocks - 1; j > GLOBAL_BLOCK; --j)
{
struct block *b = blockvector->block (j);
...

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, and so on. 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.
