+Subject: [PATCH] enable unaligned access optimizations for RISC-V with Zicclsm
+While reviewing the Redis code, we discovered that optimizations 
+for unaligned memory accesses are not enabled on RISC-V. After 
+testing siphash separately, we found some performance improvements 
+in this area and hope to add them.
+
+The zicclsm extension, which includes unaligned memory accesses, 
+is required on RISC-V, as specified in the RVA20U64 specification. 
+GCC also provides the macro zicclsm to detect the zicclsm extension.
+
+Supported versions: GCC 14.1.0 and above
