# This file is a shell script that overrides some of the tools and
# flags used on a host specific basis.

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

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

host64=false
