#define TARGET_HAS_HARDWARE_WATCHPOINTS
+/* Returns the number of hardware watchpoints of type TYPE that we can
+ set. Value is positive if we can set CNT watchpoints, zero if
+ setting watchpoints of type TYPE is not supported, and negative if
+ CNT is more than the maximum number of watchpoints of type TYPE
+ that we can support. TYPE is one of bp_hardware_watchpoint,
+ bp_read_watchpoint, bp_write_watchpoint, or bp_hardware_breakpoint.
+ CNT is the number of such watchpoints used so far (including this
+ one). OTHERTYPE is non-zero if other types of watchpoints are
+ currently enabled.
+
+ We always return 1 here because we don't have enough information
+ about possible overlap of addresses that they want to watch. As
+ an extreme example, consider the case where all the watchpoints
+ watch the same address and the same region length: then we can
+ handle a virtually unlimited number of watchpoints, due to debug
+ register sharing implemented via reference counts in go32-nat.c. */
