# 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
# SHLIB_LIBS libraries 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
