Install the new system for reporting syntax errors.
This requires the development version of Menhir, to be released soon.
In summary:
handcrafted.messages is new.
It contains a mapping of erroneous sentences to error messages,
together with a lot of comments.
Makefile.extr is new.
It contains a rule to generate cparser/pre_parser_messages.ml
based on this mapping.
cparser/ErrorReports.{ml,mli} are new.
They construct syntax error messages, based on the compiled mapping.
cparser/Lexer.mll is modified.
The last two tokens that have been read are stored in a buffer.
ErrorReports is called to construct a syntax error message.
cparser/GNUmakefile is new.
It offers several commands for working on the pre-parser.
cparser/deLexer.ml is new.
It is a script (it is not linked into CompCert).
It translates the symbolic name of a token to an example of this
token in concrete C syntax.
It is used by [make -C cparser concrete] to produce the .c files
in tests/generated/.
cparser/tests/generated/Makefile is new.
It runs ccomp, clang and gcc on each of the generated C files,
so as to allow a comparison of the error messages.
