# 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 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
|
|
# RPATH_ENVVAR environment variable used to find shared libraries
