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 64 bit types are as fast as 32 bit
12 #  HOST_64BIT_TYPE      host 64 bit type
13 #  HOST_U_64BIT_TYPE    unsigned 64 bit type (not needed if 64BIT_TYPE is long)
