30 # It is advisable to support a few --enable/--disable options to let the
31 # user select which libraries s/he really wants.
32 #
33 # Subdirectories wishing to use multilib should put the following lines
34 # in the "post-target" section of configure.in.
35 #
36 # if [ "${srcdir}" = "." ] ; then
37 # if [ "${with_target_subdir}" != "." ] ; then
38 # . ${with_multisrctop}../../config-ml.in

47 # Things are complicated because 6 separate cases must be handled:
48 # 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6.
49 #
50 # srcdir=. is special. It must handle make programs that don't handle VPATH.
51 # To implement this, a symlink tree is built for each library and for each
52 # multilib subdir.
53 #
54 # The build tree is layed out as
55 #
56 # ./
57 # newlib
58 # m68020/
59 # newlib
60 # m68881/
61 # newlib
62 #
63 # The nice feature about this arrangement is that inter-library references
64 # in the build tree work without having to care where you are. Note that
65 # inter-library references also work in the source tree because symlink trees
66 # are built when srcdir=.
67 #
68 # Unfortunately, trying to access the libraries in the build tree requires
69 # the user to manually choose which library to use as GCC won't be able to
70 # find the right one. This is viewed as the lesser of two evils.
71 #
72 # Configure variables:
73 # ${with_target_subdir} = "." for native, or ${target_alias} for cross.
74 # Set by top level Makefile.
75 # ${with_multisrctop} = how many levels of multilibs there are in the source
76 # tree. It exists to handle the case of configuring in the source tree:
77 # ${srcdir} is not constant.
78 # ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881).
79 #
80 # Makefile variables:
81 # MULTISRCTOP = number of multilib levels in source tree (+1 if cross)
82 # (FIXME: note that this is different than ${with_multisrctop}. Check out.).
83 # MULTIBUILDTOP = number of multilib levels in build tree
84 # MULTIDIRS = list of multilib subdirs (eg: m68000 m68020 ...)
85 # (only defined in each library's main Makefile).
86 # MULTISUBDIR = installed subdirectory name with leading '/' (eg: /m68000)
87 # (only defined in each multilib subdir).
89 # FIXME: Multilib is currently disabled by default for everything other than
90 # newlib. It is up to each target to turn on multilib support for the other
91 # libraries as desired.
93 # Autoconf incoming variables:
94 # srcdir, host, ac_configure_args
95 #
96 # We *could* figure srcdir and host out, but we'd have to do work that
97 # our caller has already done to figure them out and requiring these two
98 # seems reasonable.
