# sha1_block for Thumb.

#
|

# January 2007.
|
||||
#
|
||||
# The code does not present direct interest to OpenSSL, because of low
|
||||
# performance. Its purpose is to establish _size_ benchmark. Pretty
|
||||
# useless one I must say, because 30% or 88 bytes larger ARMv4 code
|
||||
# [available on demand] is almost _twice_ as fast. It should also be
|
||||
# noted that in-lining of .Lcommon and .Lrotate improves performance
|
||||
# by over 40%, while code increases by only 10% or 32 bytes. But once
|
||||
# again, the goal was to establish _size_ benchmark, not performance.
