Subject: [RFC-PATCH-for-11.0 0/5] accel/tcg: Remove some MO_TE uses in cpu_ld{uw, l, q}_code()
Date: Thu, 20 Nov 2025 18:59:09 +0100 [thread overview]
Message-ID: <20251120175914.6515-1-philmd@linaro.org> (raw)
Hi Richard,
Quick attempt to remove MO_TE uses for fixed-endianness targets.
For the other targets I started to propagate MemOp in the call
chain, but since IIUC it is constant, I wonder if it isn't simpler
to have a CPUClass::code_endian_mo field, set once with a
target_big_endian() call. I can post another RFC to show, WDYT?
Regards,
Phil.
Philippe Mathieu-Daudé (5):
accel/tcg: Add endianness variants of cpu_ld{uw,l,q}_code()
target/alpha: Use little-endian variant of cpu_ldl_code()
target/loongarch: Use little-endian variant of cpu_ldl_code()
target/sparc: Use big-endian variant of cpu_ldl_code()
target/s390x: Use big-endian variant of cpu_ld{uw,l}_code()
