1 # This file is a shell script that overrides some of the tools and
2 # flags used on a host specific basis.
4 # Since the "bfd/hosts" directory is shared by the bfd, opcodes, and
5 # binutils directories (at least), the index to it is also shared.
6 # This is that index. Each configure.in file should source this file
7 # in its per-host part.
9 # This sets the following shell variables:
10 # HDEFINES host specific compiler options
11 # host64 set to true if this is a 64 bit host
12 # HOST_64BIT_TYPE host 64 bit type
13 # SHLIB_CC compiler to use when building shared library
14 # SHLIB_CFLAGS flags to use when building shared library
15 # PICFLAG may be set to flag to use to compile PIC
16 # SHLINK may be set to the name to link the shared library to
17 # ALLLIBS may be set to libraries to build
18 # HLDFLAGS LDFLAGS specific to the host
19 # RPATH_ENVVAR environment variable used to find shared libraries
