Subject: target/m68k: Use explicit big-endian LD/ST API
X-Git-Tag: v9.2.0-rc0~60^2~5
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3a76d302047ce4518cedef7a9feca1238a00f97b;p=thirdparty%2Fqemu.git

target/m68k: Use explicit big-endian LD/ST API

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' target/m68k/); \
    done
