Add new field pw_type in the ptrace_watchpoint structure. amd64 and i386 offer the current set of watchpoints as PTRACE_PW_TYPE_DBREGS. On other archs than x86, there are readily available different types of hardware assisted watchpoints like for code-only or data-only registers on ARM. Also in future there is an option to implement MMU-based watchpoints and future per-port or per-cpu extensions. Next step is to alter this interface on x86 to generate SIGTRAP with si_code TRAP_HWWTRAP with additional information on occurred event: - which watchpoint fired, - additional watchpoint-type specific information, like on amd64 with PTRACE_PW_TYPE_DBREGS.: * only watchpoint fired * watchpoint fired and single step occurred Adjust ATF tests for the pw_type change.

$NetBSD: README,v 1.4 2012/05/18 15:36:21 jruoho Exp $ When adding new tests, please try to follow the following conventions. 1. For library routines, including system calls, the directory structure of the tests should follow the directory structure of the real source tree. For instance, interfaces available via the C library should follow: src/lib/libc/gen -> src/tests/lib/libc/gen src/lib/libc/sys -> src/tests/lib/libc/sys ... 2. Equivalently, all tests for userland utilities should try to follow their location in the source tree. If this can not be satisfied, the tests for a utility should be located under the directory to which the utility is installed. Thus, a test for env(1) should go to src/tests/usr.bin/env. Likewise, a test for tcpdump(8) should be in src/tests/usr.sbin/tcpdump, even though the source code for the program is located under src/external. 3. Otherwise use your own discretion.
