+Subject: [PATCH 1/1] rijndael-ssse3: fix counter operand from read-only to
+ read/write
+
+* cipher/rijndael-ssse3-amd64.c (_gcry_aes_ssse3_ctr_enc): Change
+'ctrlow' operand from read-only to read-write.
+--
+
+With read-only operand, compiler is allowed to pass temporary
+register to assembly block and throw away any calculation that
+have been done on that register. On the other hand, compiler is
+also allowed to keep operand value permanently in one register
+as value is treated as read-only, and effectly operates as
+expected. Selection between these two depends on compiler
+version and used flags.
+
