Subject: gdb: Implement native dumpcore function for NetBSD
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a6e6223e9a2f6ca77e064fbe8b326ac7fa205872;p=binutils-gdb.git

gdb: Implement native dumpcore function for NetBSD

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_dumpcore)
       (nbsd_nat_target::dumpcore): New declarations.
       * nbsd-nat.c (nbsd_nat_target::supports_dumpcore)
       (nbsd_nat_target::dumpcore): New functions.
