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