# Written by Andy Polyakov <appro@fy.chalmers.se> for the OpenSSL
|
|
# project. The module is, however, dual licensed under OpenSSL and
|
|
# CRYPTOGAMS licenses depending on where you obtain it. For further
|
|
# details see http://www.openssl.org/~appro/cryptogams/.

# ====================================================================

|
|
# Eternal question is what's wrong with compiler generated code? The
|
|
# trick is that it's possible to reduce the number of shifts required
|
|
# to perform rotations by maintaining copy of 32-bit value in upper
|
|
# bits of 64-bit register. Just follow mux2 and shrp instructions...
|
|
# Performance under big-endian OS such as HP-UX is 179MBps*1GHz, which
|
|
# is >50% better than HP C and >2x better than gcc.
