5# Configure fragment invoked in the post-target section for subdirs
6# wanting multilib support.
7#
8# It is advisable to support a few --enable/--disable options to let the
9# user select which libraries s/he really wants.
10#
11# Subdirectories wishing to use multilib should put the following lines
12# in the "post-target" section of configure.in.
13#
14# if [ "${srcdir}" = "." ] ; then
15#   if [ "${with_target_subdir}" != "." ] ; then
16#     . ${with_multisrctop}../../config-ml.in
17#   else
18#     . ${with_multisrctop}../config-ml.in
19#   fi
20# else
21#   . ${srcdir}/../config-ml.in
22# fi
23#
24#
25# Things are complicated because 6 separate cases must be handled:
26# 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6.
27#
28# srcdir=. is special.  It must handle make programs that don't handle VPATH.
29# To implement this, a symlink tree is built for each library and for each
30# multilib subdir.
31#
32# The build tree is layed out as
33#
34# ./
35#   newlib
36#   m68020/
37#          newlib
38#          m68881/
39#                 newlib
40#
41# The nice feature about this arrangement is that inter-library references
42# in the build tree work without having to care where you are.  Note that
43# inter-library references also work in the source tree because symlink trees
44# are built when srcdir=.
45#
46# Unfortunately, trying to access the libraries in the build tree requires
47# the user to manually choose which library to use as GCC won't be able to
48# find the right one.  This is viewed as the lesser of two evils.
49#
50# Configure variables:
51# ${with_target_subdir} = "." for native, or ${target_alias} for cross.
52# Set by top level Makefile.
53# ${with_multisrctop} = how many levels of multilibs there are in the source
54# tree.  It exists to handle the case of configuring in the source tree:
55# ${srcdir} is not constant.
56# ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881).
57#
58# Makefile variables:
59# MULTISRCTOP = number of multilib levels in source tree (+1 if cross)
60# (FIXME: note that this is different than ${with_multisrctop}.  Check out.).
61# MULTIBUILDTOP = number of multilib levels in build tree
62# MULTIDIRS = list of multilib subdirs (eg: m68000 m68020 ...)
63# (only defined in each library's main Makefile).
64# MULTISUBDIR = installed subdirectory name with leading '/' (eg: /m68000)
65# (only defined in each multilib subdir).
66
67# FIXME: Multilib is currently disabled by default for everything other than
68# newlib.  It is up to each target to turn on multilib support for the other
69# libraries as desired.
70
71# We have to handle being invoked by both Cygnus configure and Autoconf.
72#
73# Cygnus configure incoming variables:
74# srcdir, subdir, host, arguments
75#
76# Autoconf incoming variables:
77# srcdir, host, ac_configure_args
78#
79# We *could* figure srcdir and host out, but we'd have to do work that
80# our caller has already done to figure them out and requiring these two
81# seems reasonable.
82# Note that `host' in this case is GCC's `target'.  Target libraries are
83# configured for a particular host.
