Subject: [PATCH] sparc: Treat the version field in the FPU control word as reserved
Date: Fri, 12 Jan 2024 10:26:26 +0100 [thread overview]
Message-ID: <20240112092628.2464455-4-cederman@gaisler.com> (raw)
In-Reply-To: <20240112092628.2464455-1-cederman@gaisler.com>
The FSR version field is read-only and might be non-zero.
This allows math/test-fpucw* to correctly pass when the version is
non-zero.
