Subject: [PULL 06/12] hw/m68k: Use explicit big-endian LD/ST API
Date: Mon, 7 Oct 2024 13:50:21 +0200 [thread overview]
Message-ID: <20241007115027.243425-7-thuth@redhat.com> (raw)
In-Reply-To: <20241007115027.243425-1-thuth@redhat.com>
From: Philippe Mathieu-Daudé <philmd@linaro.org>
The M68K architecture uses big endianness. Directly use
the big-endian LD/ST API.
Mechanical change using:
$ end=be; \
for acc in uw w l q tul; do \
sed -i -e "s/ld${acc}_p(/ld${acc}_${end}_p(/" \
-e "s/st${acc}_p(/st${acc}_${end}_p(/" \
$(git grep -wlE '(ld|st)t?u?[wlq]_p' hw/m68k/); \
done
