# 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:
# CC compiler to use (only if needed and not already set)
# CFLAGS override CFLAGS (only if needed and not already set)
# LDFLAGS override LDFLAGS (only if needed and not already set)
# AR archiver to use (only if needed and not already set)
# RANLIB ranlib to use (only if needed and not already set)
# HDEFINES host specific compiler options
# host64 set to true if this is a 64 bit host
# HOST_64BIT_TYPE host 64 bit type
# 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

# Make sure that the left side always has two dashes. Otherwise you
# can get spurious matches. Even for unambiguous cases, do this as a

# Note that these entries cannot be fully alphabetical. Don't try.
# The order of matching is critical when multiple lines could match.
