Subject: * amd64fbsd-tdep.c (amd64fbsd_r_reg_offset): New variable.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=477f40d1aef74d9b120920517f90663e4c173cf2;p=binutils-gdb.git

* amd64fbsd-tdep.c (amd64fbsd_r_reg_offset): New variable.
(amd64fbsd_init_abi): Set TDEP->gregset_reg_offset,
TDEP->gregset_num_regs and TDEP->sizeof_gregset.  Use ARRAY_SIZE
in initialization of TDEP->sc_num_regs.
