Subject: [PATCH v2 00/11] target/arm: Fix neon reg offsets
Date: Thu, 29 Oct 2020 19:26:07 -0700 [thread overview]
Message-ID: <20201030022618.785675-1-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.
Changes for v2:
* Fix two tcg temp leaks.
