# 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: g++)
# - the compiler proper (eg: cc1plus)
# - define the names for selecting the language in LANGUAGES.
#
# $(srcdir) must be set to the gcc/ source directory (not gcc/f/).
#
# Actual name to use when installing a native compiler.
G77_INSTALL_NAME = `t='$(program_transform_name)'; echo g77 | sed $$t`

# Actual name to use when installing a cross-compiler.
G77_CROSS_NAME = `t='$(program_transform_cross_name)'; echo g77 | sed $$t`
#
# Define the names for selecting f77 in LANGUAGES.
# Note that it would be nice to move the dependency on g77
# into the F77 rule, but that needs a little bit of work
# to do the right thing within all.cross.
