# -----------------------------------------------------------------------------
# Bootstrapping

# The stage1/stage2/stage3 business is quite delicate.  Here's how it works:
# 
#  - the variable $(stage) holds the current stage number.  To build a 
#    particular stage, you say 'make stage=N' where N is 1, 2, or 3.
#    N defaults to 1.
#
#  - for stage N, object files and .hi files are placed inside 
#    the directory stageN, in subdirectories as per the sources.
#
#  - .hi-boot files are *linked* into the stageN tree, because in GHC 5.05+
#    the .hi-boot file must reside in the same place as the .hi file.
#
#  - we use explicit -o and -ohi options to direct the output from C & 
#    Haskell compilations.
#
#  - we generate a different .depend file for each build.  They need to be
#    different, because each stage might include different files: stage1
#    might not include GHCi, for example.  For each stage, a normal .depend
#    file is generated, and then post-processed to add the correct stageN/
#    prefix to each object and .hi filename.  The resulting .depend file
#    is named .depend-$(stage).  See the end of this Makefile for details.
#
#  - normal implicit rules don't work any more, because they're of the form
#
#        %.o : %.hs 
#
#    whereas we really need 
#
#	 stageN/%.o : %.hs
#
#    so suffix.mk now defines the appropriate suffix rules when
#    $(odir) is set to a non-empty value.  Here we set $(odir) to
#    stage1, stage2, or stage3.
#
#  There are other plausible designs that might work, but each has different
#  problems:
#
#  - using -odir and -hidir: GHC <= 4.08 doesn't support -hidir, and
#    anyway -odir puts all the objects in one directory (strips off the
#    subdirectory part), which eventually forces us to use VPATH to find
#    the sources.  I have a really bad feeling about VPATH.
#
#  - invoke make in the stageN subdirectory.  This probably requires VPATH
#    too.
#
#  - create a link tree.  The problem with requiring link trees is that 
#    Windows doesn't support symbolic links.

boot ::
	$(MKDIRHIER) stage$(stage)
	for i in $(ALL_DIRS); do \

# On Windows, we can't use symbolic links for the -hi-boot files
# because GHC itself is a Mingw program and does not understand
# symbolic links.  So we have to copy the files instead of link them.
# That means that if you modify a .hi-boot file in Windows, you
# have to to say 'make boot' again.
#
# PS: 'ln -s foo baz' takes 'foo' relative to the path to 'baz'
#     whereas 'cp foo baz' treats the two paths independently.
#     Hence the "../.." in the ln command line
