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