1# Configure fragment invoked in the post-target section for subdirs
2# wanting multilib support.
3#
4# It is advisable to support a few --enable/--disable options to let the
5# user select which libraries s/he really wants.
6#
7# Subdirectories wishing to use multilib should put the following lines
8# in the "post-target" section of configure.in.
9#
10# if [ "${srcdir}" = "." ] ; then
11# if [ "${with_target_subdir}" != "." ] ; then
12# . ${with_multisrctop}../../config-ml.in
13# else
14# . ${with_multisrctop}../config-ml.in
15# fi
16# else
17# . ${srcdir}/../config-ml.in
18# fi

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

620# of course.
621# MULTIDIRS is non-empty for the cpu top level Makefile (eg: newlib/Makefile)
622# and lists the subdirectories to recurse into.
623# MULTISUBDIR is non-empty in each cpu subdirectory's Makefile
624# (eg: newlib/h8300h/Makefile) and is the installed subdirectory name with
625# a leading '/'.
626# MULTIDO is used for targets like all, install, and check where
627# $(FLAGS_TO_PASS) augmented with the subdir's compiler option is needed.
628# MULTICLEAN is used for the *clean targets.
629#
630# ??? It is possible to merge MULTIDO and MULTICLEAN into one. They are
631# currently kept separate because we don't want the *clean targets to require
632# the existence of the compiler (which MULTIDO currently requires) and
633# therefore we'd have to record the directory options as well as names
634# (currently we just record the names and use --print-multi-lib to get the
635# options).
