-       * x86/aes-encrypt-internal.asm: Updated use of AES_SUBST_BYTE.
+       * x86/aes-encrypt-internal.asm: Replaced pushl and popl in the
+       loop with movl. Eliminated redundant movl.
        * x86/aes-decrypt-internal.asm: Likewise.
-       * x86/aes.m4 (BYTEREG): New macro.
-       (AES_SUBST_BYTE): Take state registers as argument. Use BYTEREG to

+       * x86_64/aes.m4: New file.
+
+       * x86/aes-encrypt-internal.asm: Updated for AES_FINAL_ROUND. Only
+       three times through the substitution loop.
+       * x86/aes-decrypt-internal.asm: Likewise.
