Subject: [PATCH  v3 06/20] target/arm: use gdb_get_reg helpers
Date: Wed, 11 Dec 2019 17:05:06 +0000	[thread overview]
Message-ID: <20191211170520.7747-7-alex.bennee@linaro.org> (raw)
In-Reply-To: <20191211170520.7747-1-alex.bennee@linaro.org>

This is cleaner than poking memory directly and will make later
clean-ups easier.

v2
  - make sure we pass hi/lo correctly as quads are stored in LE order
