-# This is drop-in MIPS III/IV ISA replacement for crypto/bn/bn_asm.c.
-#
-# The module is designed to work with either of the "new" MIPS ABI(5),
-# namely N32 or N64, offered by IRIX 6.x. It's not ment to work under
-# IRIX 5.x not only because it doesn't support new ABIs but also
-# because 5.x kernels put R4x00 CPU into 32-bit mode and all those
-# 64-bit instructions (daddu, dmultu, etc.) found below gonna only
-# cause illegal instruction exception:-(
-#
-# In addition the code depends on preprocessor flags set up by MIPSpro
-# compiler driver (either as or cc) and therefore (probably?) can't be
-# compiled by the GNU assembler. GNU C driver manages fine though...
-# I mean as long as -mmips-as is specified or is the default option,
-# because then it simply invokes /usr/bin/as which in turn takes
-# perfect care of the preprocessor definitions. Another neat feature
-# offered by the MIPSpro assembler is an optimization pass. This gave
-# me the opportunity to have the code looking more regular as all those
-# architecture dependent instruction rescheduling details were left to
-# the assembler. Cool, huh?
-#
-# Performance improvement is astonishing! 'apps/openssl speed rsa dsa'
-# goes way over 3 times faster!
-#
-# <appro@fy.chalmers.se>
-
-# October 2010
-#
-# Adapt the module even for 32-bit ABIs and other OSes. The former was
-# achieved by mechanical replacement of 64-bit arithmetic instructions
-# such as dmultu, daddu, etc. with their 32-bit counterparts and
-# adjusting offsets denoting multiples of BN_ULONG. Above mentioned
-# >3x performance improvement naturally does not apply to 32-bit code
-# [because there is no instruction 32-bit compiler can't use], one
-# has to content with 40-85% improvement depending on benchmark and
-# key length, more for longer keys.
