# 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.
