Subject: [PATCH 00/11] target/arm: Fix neon reg offsets
Date: Tue, 27 Oct 2020 20:26:52 -0700 [thread overview]
Message-ID: <20201028032703.201526-1-richard.henderson@linaro.org> (raw)
Much of the existing usage of neon_reg_offset is broken for
big-endian hosts, as it computes the offset of the first
32-bit unit, not the offset of the entire vector register.
Fix this by separating out the different usages. Make the
whole thing look a bit more like the aarch64 code.

Richard Henderson (11):
target/arm: Introduce neon_full_reg_offset
target/arm: Move neon_element_offset to translate.c
target/arm: Use neon_element_offset in neon_load/store_reg
target/arm: Use neon_element_offset in vfp_reg_offset
target/arm: Add read/write_neon_element32
target/arm: Expand read/write_neon_element32 to all MemOp
target/arm: Rename neon_load_reg32 to vfp_load_reg32
