# Configure fragment invoked in the common section for subdirs
|
|
# wanting multilib support.
|
|
#
|
|
# The common section was chosen because xiberty clobbers $srcdir in the
|
|
# common section of its configure.in.
|
|
#
|
|
# The intent is to keep as much of this in one place as possible (and out
|
|
# of each subdirectory, eg: newlib, libio, etc.) until the right way to do
|
|
# this (ha ha) is decided upon.
|
|
#
|
|
# This is where a target selects what multilib directories to build.
|
|
# It is advisable to support a few --enable/--disable options to let the
|
|
# user select which libraries s/he really wants.
|
|
#
|
|
# FIXME: Multilib is currently disabled by default for everything other than
|
|
# newlib. It is up to each target to turn on multilib support for the other
|
|
# libraries as desired.
|
|
#
|
|
# FIXME: It would be better if we could use the --print-multi-lib switch to
|
|
# gcc to get the list of directories to build, but at this point the compiler
|
|
# has not been built.
|
|
|
|
# Only do this if --enable-multilib.
|
|
# And only if at the top level, not a multilib subdirectory.
