Subject: hw/loongarch: Use explicit little-endian LD/ST API
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2d3c00965a482d89fc4f0af70e5012a768680e31;p=thirdparty%2Fqemu.git

hw/loongarch: Use explicit little-endian LD/ST API

The LoongArch 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' hw/loongarch/); \
    done
