PR9605 gdb/ * breakpoint.c (insert_bp_location): If inserting the read watchpoint failed, fallback to an access watchpoint. (bpstat_check_watchpoint): Stop for read watchpoint triggers even if the value changed, if not watching the same memory for writes. (watchpoint_locations_match): Add comment. (update_global_location_list): Copy the location's watchpoint type. * i386-nat.c (i386_length_and_rw_bits): It's an internal error to handle read watchpoints here. (i386_insert_watchpoint): Read watchpoints aren't supported. * remote.c (remote_insert_watchpoint): Return 1 for unsupported packets. * target.h (target_insert_watchpoint): Update description. 2010-02-22 Pedro Alves <pedro@codesourcery.com> PR9605 gdbserver/ * i386-low.c (i386_length_and_rw_bits): Throw a fatal error if handing a read watchpoint. (i386_low_insert_watchpoint): Read watchpoints aren't supported. 2010-02-22 Pedro Alves <pedro@codesourcery.com> PR9605 gdb/testsuite/ * gdb.base/watch-read.c, gdb.base/watch-read.exp: New files.
