Tue Jul 28 15:46:02 GMT 2020
Define supports_dumpcore and dumpcore for NetBSD, that wraps
the ptrace(2) call with the PT_DUMPCORE operation.
gdb/ChangeLog:
* nbsd-nat.h (nbsd_nat_target::supports_native_dumpcore)
(nbsd_nat_target::native_dumpcore): New declarations.
* nbsd-nat.c (nbsd_nat_target::supports_native_dumpcore)
(nbsd_nat_target::native_dumpcore): New functions.
