Add new ptrace(2) calls:
- PT_COUNT_WATCHPOINTS - count the number of available hardware watchpoints
- PT_READ_WATCHPOINT - read struct ptrace_watchpoint from the kernel state
- PT_WRITE_WATCHPOINT - write new struct ptrace_watchpoint state, this
includes enabling and disabling watchpoints
The ptrace_watchpoint structure contains MI and MD parts:
typedef struct ptrace_watchpoint {
int pw_index; /* HW Watchpoint ID (count from 0) */
lwpid_t pw_lwpid; /* LWP described */
struct mdpw pw_md; /* MD fields */
} ptrace_watchpoint_t;
For example amd64 defines MD as follows:
struct mdpw {
void *md_address;
int md_condition;
int md_length;
};
These calls are protected with the __HAVE_PTRACE_WATCHPOINTS guard.
Tested on amd64, initial support added for i386 and XEN.
