  19 # flags used on a host specific basis.

  21 # Since the "bfd/hosts" directory is shared by the bfd, opcodes, and
  22 # binutils directories (at least), the index to it is also shared.
  23 # This is that index.  Each configure.ac file should source this file
  24 # in its per-host part.

  26 # This sets the following shell variables:
  27 #  HDEFINES             host specific compiler options
  28 #  host64               set to true if 64 bit types are as fast as 32 bit
  29 #  HOST_64BIT_TYPE      host 64 bit type
  30 #  HOST_U_64BIT_TYPE    unsigned 64 bit type (not needed if 64BIT_TYPE is long)
