25#	Configuration and targets for bignum module
26#	specific to AMD 64-bit architecture, amd64.
27#
28# Bignum configuration (BIGNUM_CFG):
29#   PSR_MUL:
30#       There is a processor-specific implementation bignum multiply functions
31#   HWCAP:
32#       There are multiple implementations of bignum functions, and the
33#	appropriate one must be chosen at run time, based on testing
34#	hardware capabilites.
35#
36# -DPSR_MUL:
37# For AMD64, there is a processor-specific implementation of
38# the bignum multiply functions, which takes advantage of the
39# 64x64->128 bit multiply instruction.
40#
41# -UHWCAP:
42# There is only one implementation, because the 128 bit multiply using
43# general-purpose registers is faster than any MMX or SSE2 implementation.
