Subject: target/loongarch: Use explicit little-endian LD/ST API
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2a99b2af2c3d3aa3751b005c575b8f0713abb88d;p=qemu.git

target/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' target/loongarch/); \
    done
