Subject: [Qemu-devel] [PATCH v3 01/31] include/exec/helper-head.h: support f16 in helper calls
Date: Fri, 23 Feb 2018 15:36:06 +0000	[thread overview]
Message-ID: <20180223153636.29809-2-alex.bennee@linaro.org> (raw)
In-Reply-To: <20180223153636.29809-1-alex.bennee@linaro.org>

This allows us to explicitly pass float16 to helpers rather than
assuming uint32_t and dealing with the result. Of course they will be
passed in i32 sized registers by default.
