When trying to run gdbserver compiled for x86 win32 under wine, I get:
$ wine ./gdbserver/gdbserver.exe --once :1234 ./test
/home/emaisin/src/binutils-gdb/gdb/gdbserver/regcache.c:177: A problem internal to GDBserver has been detected.
regcache* new_register_cache(const target_desc*): Assertion `tdesc->registers_size != 0' failed.
It seems like on that platform, init_target_desc is never called, so
registers_size is never computed.
My first thought was to call init_target_desc somewhere in win32-low.c,
but it turns out that when using win32 on arm, the target description is
already initialized by the generated code. My second thought was to
call it in {i386,amd64}_create_target_description, but those functions
are shared with GDB, and init_target_desc is gdbserver-specific. So I
ended up with the simplest fix, calling it in i386_arch_setup.
Now I hit some other problem:
$ wine ./gdbserver/gdbserver.exe --once :1234 ./test
Killing process(es): 39
No program to debug
Exiting
but still, I think fixing the tdesc issue this is a step forward.
gdb/gdbserver/ChangeLog:
* win32-i386-low.c (i386_arch_setup): Call init_target_desc.
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.
