Subject: [PATCH] sparc: Do not test preservation of NaN payloads for LEON
Date: Fri, 12 Jan 2024 10:26:23 +0100 [thread overview]
Message-ID: <20240112092628.2464455-1-cederman@gaisler.com> (raw)
The FPU used by LEON does not preserve NaN payload. This change allows
the math/test-*-canonicalize tests to pass on LEON.
Signed-off-by: Daniel Cederman <cederman@gaisler.com>
