Subject: target/hexagon: Use explicit little-endian LD/ST API
X-Git-Tag: v9.2.0-rc0~46^2~25
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ae412c021088da9f977f6407fedef652fb4c43db;p=thirdparty%2Fqemu.git

target/hexagon: Use explicit little-endian LD/ST API

The Hexagon architecture uses little endianness. Directly use
the little-endian LD/ST API.

Mechanical change using:

  $ end=le; \
    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/hexagon/); \
    done
