Subject: target/alpha: Use explicit little-endian LD/ST API
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=954072d255837e12bb6fd1aa6cae74a44fe5c7e2;p=thirdparty%2Fqemu.git

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

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

Mechanical change running:

  $ for a in uw w l q; do \
      sed -i -e "s/ld${a}_p(/ld${a}_le_p(/" \
        $(git grep -wlE '(ld|st)u?[wlq]_p' target/alpha/);
    done
