# 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.in 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)
#  SHLIB_CC		compiler to use when building shared library
#  SHLIB_CFLAGS		flags to use when building shared library
#  PICFLAG		may be set to flag to use to compile PIC
#  SHLINK		may be set to the name to link the shared library to
#  ALLLIBS		may be set to libraries to build
#  HLDFLAGS		LDFLAGS specific to the host
#  HLDENV		environment variable to set when linking for the host
#  RPATH_ENVVAR		environment variable used to find shared libraries
#  INSTALL_SHLIB	install a shared library
