[v2] misc: Use explicit endian LD/ST API

[PATCH v2 06/25] target/alpha: Use explicit little-endian LD/ST API

Posted by Philippe Mathieu-Daudé 1 month, 3 weeks ago

The Alpha 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/alpha/); \
    done
