The recent change to reload_shared_libraries() broke FDPIC shared libraries as the solib-frv.c code was implicitly relying on the initial order of calls (first solib_addr() and then solib_create_inferior_hook()). It was maintaining internal state via enable_break{1,2}_done to handle this. While I could tweak these values a bit more, the original code wasn't terribly bullet proof -- if during the initial debug you attempted to view shared libraries, the enable2_break() code would whine about the ldso internal debug addresses being unfetchable (and would actually attempt to read address 0x8 on the target). So I've dropped this implicit dependency on order (i.e. enable_break1_done) and updated the ldso poking code (i.e. enable_break2) to silently return when the internal debug address is still set to 0. It will remain this way until the ldso gets a chance to initialize at which point the code will act the same as before. While I have no way of testing the FRV, the Blackfin FDPIC code is using this same base in a 100% copy & paste method since we implemented FDPIC the same way as the FRV guys (I'll address this in the future). This fix was required in order to handle shared libraries with Blackfin FDPIC properly, and I see no reason why it wouldn't also work for FRV (since the uClibc ldso FDPIC code is the same too and that's really what this is poking).

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.
