20 # This file provides the language dependent support in the main Makefile.
21 # Each language makefile fragment must provide the following targets:
23 # foo.all.cross, foo.start.encap, foo.rest.encap,
24 # foo.install-common, foo.install-man, foo.install-info, foo.install-pdf,
25 # foo.install-html, foo.info, foo.dvi, foo.pdf, foo.html, foo.uninstall,
26 # foo.mostlyclean, foo.clean, foo.distclean,
27 # foo.maintainer-clean, foo.stage1, foo.stage2, foo.stage3, foo.stage4
29 # where `foo' is the name of the language.
31 # It should also provide rules for:
33 # - making any compiler driver (eg: gcc)
34 # - the compiler proper (eg: cc1)
35 # - define the names for selecting the language in LANGUAGES.
38 # Define the names for selecting c in LANGUAGES.
41 # Tell GNU make to ignore these if they exist.
44 # The C front end driver. This is different from the drivers for other
45 # front ends, because there is no C language specific driver (i.e. nothing
46 # is to cc1 as e.g. g++ is to cc1plus, or gfortran is to f951).
