Subject: target/rx: Use explicit little-endian LD/ST API
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=41a1b46c3b294b046b439fb46febf4b4a16d9350;p=thirdparty%2Fqemu.git

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

The RX 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/rx/); \
    done
