+       * sparc/aes.asm (_aes_crypt): Moved increment of src into the
+       source_loop. Also fixed stop condition, the loop was run 5 times,
+       not 4, as it should.
+       (_aes_crypt): Use src directly when accessing the source data,
+       don't use %o5.
+       (_aes_crypt): Renamed variables in source_loop.
+       (_aes_crypt): Changed stop condition in source_loop to not depend
+       on i. Finally reduced the source_loop to 16 instructions. Also
+       increased the alignment of the code to 16.
+       (_aes_crypt): In final_loop, use preshifted indices.
+       (_aes_crypt): In final_loop, construct the result in t0. Use t0-t3
+       for intermediate values.
+       (_aes_crypt): In final_loop, use the register idx.
+       (_aes_crypt): In final_loop, keep i multiplied by 4. Use key to
+       get to the current roundkey.
+       (_aes_crypt): In final_loop, use i for indexing.
+       (_aes_crypt): Update dst in the output loop. This yields a delay
+       slot that isn't filled yet.
+       (_aes_crypt): Decrement round when looping, saving yet some
+       instructions.
+       (_aes_crypt): Reformatted code as blocks of four instructions
+       each.
+       (_aes_crypt): Copy the addresses of the indexing tables into
+       registers at the start. No more need for the idx register.
+       (_aes_crypt): Deleted idx register.
+       (_aes_crypt): Some peep hole optimizations, duplicating some
+       instructions to fill nop:s, and put branch instructions on even
+       word addresses.

+
+       * sparc/aes.asm (_aes_crypt): Moved some more additions out of the
+       inner loop, using additional registers.
+       (_aes_crypt): Deleted one more addition from the inner loop, by
+       using the subkey pointer.

        * configure.in (asm_path): Renamed "path" to "asm_path". Also look
