Subject: [Qemu-devel] [PULL 02/22] include/fpu/softfloat: remove USE_SOFTFLOAT_STRUCT_TYPES
Date: Wed, 21 Feb 2018 11:05:02 +0000	[thread overview]
Message-ID: <20180221110523.859-3-alex.bennee@linaro.org> (raw)
In-Reply-To: <20180221110523.859-1-alex.bennee@linaro.org>

It's not actively built and when enabled things fail to compile. I'm
not sure the type-checking is really helping here. Seeing as we "own"
our softfloat now lets remove the cruft.
