# This file provides the language dependent support in the main Makefile.
# Each language makefile fragment must provide the following targets:
#
# foo.all.build, foo.all.cross, foo.start.encap, foo.rest.encap,
# foo.info, foo.dvi,
# foo.install-normal, foo.install-common, foo.install-info, foo.install-man,
# foo.uninstall, foo.distdir,
# foo.mostlyclean, foo.clean, foo.distclean, foo.extraclean,
# foo.maintainer-clean, foo.stage1, foo.stage2, foo.stage3, foo.stage4
#
# where `foo' is the name of the language.
#
# It should also provide rules for:
#
# - making any compiler driver (eg: g77)
# - the compiler proper (eg: f771)
# - define the names for selecting the language in LANGUAGES.
#
# $(srcdir) must be set to the gcc/ source directory (not gcc/f/).
#
# Extra flags to pass to recursive makes (and to sub-configure).
# Use different quoting rules compared with FLAGS_TO_PASS so we can use
# this to set environment variables as well
# Note that GCC_FOR_TARGET, GCC_FLAGS aren't in here -- treated separately.

# This dance is all about producing accurate documentation for g77's
# intrinsics with minimum fuss.  f/ansify appends "\n\" to C strings
# so ANSI C compilers can compile f/intdoc.h -- gcc can compile f/intdoc.in
# directly, if f/intdoc.c #include'd that, but we don't want to force
# people to install gcc just to build the documentation.  We use the
# C format for f/intdoc.in in the first place to allow a fairly "free",
# but widely known format for documentation -- basically anyone who knows
# how to write texinfo source and enclose it in C constants can handle
# it, and f/ansify allows them to not even end lines with "\n\".  So,
# essentially, the C preprocessor and compiler are used to enter the
# document snippets into a data base via name lookup, rather than duplicating
# that kind of code here.  And we use f/intdoc.c instead of straight
# texinfo in the first place so that as much information as possible
# contained in f/intrin.def can be inserted directly and reliably into
# the documentation.  That's better than replicating it, because it
# reduces the likelihood of discrepancies between the docs and the compiler
# itself, which uses f/intrin.def; in fact, many bugs in f/intrin.def have
# been found only upon reading the documentation that was automatically
# produced from it.
