+	* aes-internal.h (struct aes_table): Renamed the shift_idx field
+	to sparc_idx, as it will be tweaked to improve the sparc code.
+	Also reduced its size to [2][4].
+	(IDX_FACTOR): Deleted constant.
+	* aes-encrypt-table.c (_aes_encrypt_table): Adapted initializer of
+	sparc_idx. 
+	* aes-decrypt-table.c (_aes_decrypt_table): Likewise.
+	* asm.m4: Deleted AES_SIDX2, to match struct aes_table.
