#	Configuration and targets for bignum module
#	specific to AMD 64-bit architecture, amd64.
#
# Bignum configuration (BIGNUM_CFG):
#   PSR_MUL:
#       There is a processor-specific implementation bignum multiply functions
#   HWCAP:
#       There are multiple implementations of bignum functions, and the
#	appropriate one must be chosen at run time, based on testing
#	hardware capabilites.
#
# -DPSR_MUL:
# For AMD64, there is a processor-specific implementation of
# the bignum multiply functions, which takes advantage of the
# 64x64->128 bit multiply instruction.
#
# -UHWCAP:
# There is only one implementation, because the 128 bit multiply using
# general-purpose registers is faster than any MMX or SSE2 implementation.
