Add support for hardware watchpoints on win32 native. * win32-nat.c (CONTEXT_DEBUG_DR macro): Add use of CONTEXT_DEBUG_REGISTERS. (dr variable): New variable. Static array containing a local copy of debug registers. (debug_registers_changed): New variable. Reflects when debug registers are changed and need to be written to inferior. (debug_registers_used): New variable. Reflects when any debug register was set, used when new threads are created. (cygwin_set_dr, cygwin_set_dr7, cygwin_get_dr6): New functions used by i386-nat code. (thread_rec): Set dr array if id is the thread of current_event . (child_continue, child_resume): Change the debug registers for all threads if debug_registers_changed. (child_add_thread): Change the debug registers if debug_registers_used. * config/i386/cygwin.mh: Add use of i386-nat.o file. Link nm.h to new nm-cygwin.h file. + config/i386/nm-cygwin.h: New file. Contains the macros used for use of hardware registers.
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.
