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 # CC compiler to use (only if needed and not already set)
11 # CFLAGS override CFLAGS (only if needed and not already set)
12 # LDFLAGS override LDFLAGS (only if needed and not already set)
13 # AR archiver to use (only if needed and not already set)
14 # RANLIB ranlib to use (only if needed and not already set)
15 # HDEFINES host specific compiler options
16 # host64 set to true if this is a 64 bit host
17 # HOST_64BIT_TYPE host 64 bit type
18 # SHLIB_CC compiler to use when building shared library
19 # SHLIB_CFLAGS flags to use when building shared library
20 # PICFLAG may be set to flag to use to compile PIC
21 # SHLINK may be set to the name to link the shared library to
22 # ALLLIBS may be set to libraries to build
23 # HLDFLAGS LDFLAGS specific to the host
24 # RPATH_ENVVAR environment variable used to find shared libraries
31 # WHEN ADDING ENTRIES TO THIS MATRIX:
32 # Make sure that the left side always has two dashes. Otherwise you
33 # can get spurious matches. Even for unambiguous cases, do this as a
34 # convention, else the table becomes a real mess to understand and maintain.
36 # Note that these entries cannot be fully alphabetical. Don't try.
37 # The order of matching is critical when multiple lines could match.
