2002-02-04 Pierre Muller <muller@ics.u-strasbg.fr> 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.
