Subject: [PATCH 2/5] fbsd-nat: Use regset supply/collect methods.
Date: Thu, 7 Jul 2022 17:58:13 -0700 [thread overview]
Message-ID: <20220708005816.9408-3-jhb@FreeBSD.org> (raw)
In-Reply-To: <20220708005816.9408-1-jhb@FreeBSD.org>
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.
