This patch removes VEC (mem_region). Doing so requires touching a lot of little things here and there. The fields in mem_attrib are now initialized during construction. The values match those that were in default_mem_attrib (now removed). unknown_mem_attrib is also removed, and replaced with a static method (mem_attrib::unknown) that returns the equivalent. mem_region is initialized in a way similar to mem_region_init (now removed) did. I found the organization of mem_region_list and target_mem_region_list a bit confusing. Sometimes mem_region_list points to the same vector as target_mem_region_list (and therefore does not own it), and sometimes (when the user manually edits the mem regions) points to another vector, and in this case owns it. To avoid this ambiguity, I think it is simpler to have two vectors, one for target-defined regions and one for user-defined regions, and have mem_region_list point to one or the other. There are now no vector objects dynamically allocated, both are static. The make-target-delegates script does not generate valid code when a target method returns a type with a parameter list. For this reason, I created a typedef (mem_region_vector) that's only used in the target_ops structure. If you speak perl, you are welcome to improve the script! Regtested on the buildbot. gdb/ChangeLog: * memattr.h: Don't include vec.h. (struct mem_attrib): Initialize fields. <unknown>: New static method.

README
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.
