Subject: [RFC-PATCH-for-11.0 v3 14/21] target/s390x: Use little-endian variant of cpu_ld/st_data*()
Date: Fri, 21 Nov 2025 14:44:56 +0100 [thread overview]
Message-ID: <20251121134503.30914-15-philmd@linaro.org> (raw)
In-Reply-To: <20251121134503.30914-1-philmd@linaro.org>
We only build the S390x target using little endianness order,
therefore the cpu_ld/st_data*() definitions expand to the little
endian declarations. Use the explicit little-endian variants.
Mechanical change running:
$ tgt=s390x; \
end=be; \
for op in data mmuidx_ra; do \
for ac in uw sw l q; do \
sed -i -e "s/cpu_ld${ac}_${op}/cpu_ld${ac}_${end}_${op}/" \
$(git grep -l cpu_ target/${tgt}/); \
done;
for ac in w l q; do \
sed -i -e "s/cpu_st${ac}_${op}/cpu_st${ac}_${end}_${op}/" \
$(git grep -l cpu_ target/${tgt}/); \
done;
done
