39 # A "platform" is the GNU cpu-type/manufacturer/operating-system target machine
40 # specifier. E.g. sparc-sun-solaris2
41 #
42 # Build platform: the platform on which we are doing this build
43 # Host platform: the platform on which these binaries will run
44 # Target platform: the platform for which this compiler will generate code
45 #
46 # We don't support build & host being different, because the build
47 # process creates binaries that are run during the build, and also
48 # installed.
49 #
50 # If host & target are different, then we are building a compiler
51 # which will generate intermediate .hc files to port to the target
52 # architecture for bootstrapping. The libraries and stage 2 compiler
53 # will be built as HC files for the target system, and likely won't
54 # build on this host platform.
55 #
56 # An important invariant is that for any piece of source code, the
57 # platform on which the code is going to run is the HOST platform,
58 # and the platform on which we are building is the BUILD platform.
59 # Additionally for the compiler, the platform this compiler will
60 # generate code for is the TARGET. TARGET is not meaningful outside
61 # the compiler sources.
62 #
63 # Guidelines for when to use HOST vs. TARGET:
64 #
65 # - In the build system (Makefile, foo.mk), normally we should test
66 # $(HOSTPLATFORM). There are some cases (eg. installation), where
67 # we expect $(HOSTPLATFORM)==$(TARGETPLATFORM), so in those cases it
68 # doesn't matter which is used.
69 #
70 # - In the compiler itself, we should test HOST or TARGET depending
71 # on whether the conditional relates to the code being generated, or
72 # the platform on which the compiler is running. See the section
73 # on "Coding Style" in the commentary for more details.
74 #
75 # - In all other code, we should be testing HOST only.
76 #
77 # NOTE: cross-compiling is not well supported by the build system.
78 # You have to do a lot of work by hand to cross compile: see the
79 # section on "Porting GHC" in the Building Guide.
