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: g++)
34 # - the compiler proper (eg: cc1plus)
35 # - define the names for selecting the language in LANGUAGES.
38 # Define the names for selecting jit in LANGUAGES.
39 # Note that it would be nice to move the dependency on g++
40 # into the jit rule, but that needs a little bit of work
41 # to do the right thing within all.cross.

195 # Documentation build hooks.
197 # The documentation can be built using the texinfo toolchain, or
198 # the sphinx toolchain
200 # The jit documentation is authored using Sphinx, which has numerous
201 # advantages over Texinfo, including:
205 # * use of CSS and JS to provide less of a 1990s feel in the generated
208 # * sane, stable HTML page and anchor names
210 # * sane HTML navigation: ability to move forward and back in the HTML
211 # at every node to read the HTML like a book
213 # * syntax-coloring of examples
215 # * the ability to "include" fragments of code inline. This is used
216 # heavily by the jit docs, so that the example code is shared by both
217 # the test suite and the documentation to ensure that the examples
218 # appearing in the docs actually compile and work
220 # Sphinx is not a "blessed" dependency, and so a prebuilt libgccjit.texinfo
221 # file built by Sphinx is checked into the source tree to avoid requiring
222 # everyone to have Sphinx installed.
224 # This prebuilt libgccjit.texinfo has the "include" fragments "baked in",
225 # and so contains the content from the sphinx toolchain, but lacks the
226 # syntax-coloring, and the generated HTML is (IMHO) greatly inferior to
227 # that generated by Sphinx.
229 # These targets redirect HTML creation and installation to either
230 # jit.sphinx.(install-)html or jit.texinfo.(install-)html.
