# will be built as HC files for the target system, and likely won't
# build on this host platform.
#
+# An important invariant is that for any piece of source code, the
+# platform on which the code is going to run is the HOST platform,
+# and the platform on which we are building is the BUILD platform.
+# Additionally for the compiler, the platform this compiler will
+# generate code for is the TARGET. TARGET is not meaningful outside
+# the compiler sources.
+#
# Guidelines for when to use HOST vs. TARGET:
#
# - In the build system (Makefile, foo.mk), normally we should test
#
# - In the compiler itself, we should test HOST or TARGET depending
# on whether the conditional relates to the code being generated, or
-# the platform on which the compiler is running. For stage 2,
-# HOSTPLATFORM should be reset to be TARGETPLATFORM (we currently
-# don't do this, but we should).
+# the platform on which the compiler is running. See the section
+# on "Coding Style" in the commentary for more details.
#
-# - In the RTS and library code, we should be testing TARGET only.
+# - In all other code, we should be testing HOST only.
#
# NOTE: cross-compiling is not well supported by the build system.
# You have to do a lot of work by hand to cross compile: see the
# thr_p : threaded profiled
# debug : debugging (compile with -g for the C compiler, and -DDEBUG)
# debug_p : debugging profiled
+# debug_u : debugging unregisterised
# thr_debug : debugging threaded
# thr_debug_p : debugging threaded profiled
#
#
# -O is pretty desirable, otherwise no inlining of prelude
# things (incl "+") happens when compiling with this compiler
+#
+# -fgenerics switches on generation of support code for
+# derivable type classes. This is now off by default,
+# but we switch it on for the libraries so that we generate
+# the code in case someone importing wants it
