Subject: fbsd-nat: Use regset supply/collect methods.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5dd6c79a323a9ca7bf8d5db3206532580365127e;p=binutils-gdb.git

fbsd-nat: Use regset supply/collect methods.

fbsd-nat includes various helper routines for fetching and storing
register sets via ptrace where the register set is described by a
regset.  These helper routines directly invoke the
supply/collect_regset regcache methods which doesn't permit a regset
to provide custom logic when fetching or storing a register set.
Instead, just use the function pointers from the struct regset
directly.
