# 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
39
#   else
40
#     . ${with_multisrctop}../config-ml.in
41
#   fi

# else
43
#   . ${srcdir}/../config-ml.in

# fi

#
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).
88
 
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.

95

# our caller has already done to figure them out and requiring these two
98
# seems reasonable.
