+Subject: [PATCH 01/21] softfloat: Extend float_exception_flags to 16 bits
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+We will shortly have more than 8 bits of exceptions.
+Repack the existing flags into low bits and reformat to hex.
+
+Upstream-Status: Backport
