Subject: [PATCH v2 25/25] hw/ppc/e500: Use explicit big-endian LD/ST API
Date: Fri,  4 Oct 2024 13:30:41 -0300	[thread overview]
Message-ID: <20241004163042.85922-26-philmd@linaro.org> (raw)
In-Reply-To: <20241004163042.85922-1-philmd@linaro.org>

The 32-bit PPC architecture uses big endianness. Directly use
the big-endian LD/ST API for the E500 hardware.

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/*/*e500*); \
    done
