#  This is the Makefile for the runtime-system stuff.
#  This stuff is written in C (and cannot be written in Haskell).
#
#  Things are organised into exactly one level of subdirs.
#
#  At the moment, there are a few such subdirs:
#	c-as-asm	-- mini-interpreter & register hackery
#	gum		-- GUM-specific stuff
#	main		-- "main", associated startup stuff, & MISC things
#	prims		-- code for primitives that must be written in C
#	profiling	-- cost-centre profiling
#	storage		-- the storage manager(s)
#
#  We create two libraries.  One, libHSrts<tag>.a, is built separately
#  for each "build".  The other, libHSclib.a is built once: it is just
#  .lc files that end up the same no matter what, i.e. completely
#  ordinary C.

#  Other sorta independent, compile-once subdirs are:

#	gmp		-- GNU multi-precision library (for Integer)

# If you use EXTRA_HC_OPTS on the command line (which you shouldn't,
# strictly speaking), it will probably work -- it is pinned onto
