Subject: [PATCH v3 73/88] include/hw/elf: Remove truncating signed casts
Date: Wed, 1 Nov 2023 18:30:01 -0700 [thread overview]
Message-ID: <20231102013016.369010-74-richard.henderson@linaro.org> (raw)
In-Reply-To: <20231102013016.369010-1-richard.henderson@linaro.org>
There's nothing about elf that specifically requires signed vs unsigned.
This is very much a target-specific preference.
In the meantime, casting low and high from uint64_t back to Elf_SWord
to uint64_t discards high bits that might have been set by translate_fn.
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
