   1 # Configure fragment invoked in the common section for subdirs
   2 # wanting multilib support.
   3 #
   4 # The common section was chosen because xiberty clobbers $srcdir in the
   5 # common section of its configure.in.
   6 #
   7 # The intent is to keep as much of this in one place as possible (and out
   8 # of each subdirectory, eg: newlib, libio, etc.) until the right way to do
   9 # this (ha ha) is decided upon.
  10 #
  11 # This is where a target selects what multilib directories to build.
  12 # It is advisable to support a few --enable/--disable options to let the
  13 # user select which libraries s/he really wants.
  14 #
  15 # FIXME: Multilib is currently disabled by default for everything other than
  16 # newlib.  It is up to each target to turn on multilib support for the other
  17 # libraries as desired.
  18 #
  19 # FIXME: It would be better if we could use the --print-multi-lib switch to
  20 # gcc to get the list of directories to build, but at this point the compiler
  21 # has not been built.
  22
  23 # Only do this if --enable-multilib.
  24 # And only if at the top level, not a multilib subdirectory.
  25

  27
  28 # Doing this in the common section means ${target} isn't set yet, so compute
  29 # a copy here.  This is a bit kludgey, but again the current (short term) goal
  30 # is to be as unobtrusive (sp?) to the rest of the sources as possible.
