This patch generalizes diagnostic_context so that rather than having
a single output format, it has a vector of zero or more.
It adds new two options:
-fdiagnostics-add-output=DIAGNOSTICS-OUTPUT-SPEC
-fdiagnostics-set-output=DIAGNOSTICS-OUTPUT-SPEC
which both take a new configuration syntax of the form SCHEME ("text" or
"sarif"), optionally followed by ":" and one or more KEY=VALUE pairs,
in this form:
<SCHEME>
<SCHEME>:<KEY>=<VALUE>
<SCHEME>:<KEY>=<VALUE>,<KEY2>=<VALUE2>
...etc
where each SCHEME supports some set of keys. For example, it's now
possible to use:
-fdiagnostics-add-output=sarif:version=2.1,file=foo.2.1.sarif \
-fdiagnostics-add-output=sarif:version=2.2-prerelease,file=foo.2.2.sarif
to add a pair of outputs, each writing to a different file, using
versions 2.1 and 2.2 of the SARIF standard respectively, whilst also
emitting the classic text form of the diagnostics to stderr.
I hope the new syntax gives us room to potentially add new kinds of
output sink in the future (e.g. RPC notifications), and to add new
key/value pairs as needed by the different sinks.
Implementation-wise, the diagnostic_context's m_printer which previously
was used directly by the single output format now becomes a "reference
printer", created by the client (such as the frontend), with defaults
modified by command-line options. Each of the multiple output sinks has
its own pretty_printer instance, created by cloning the context's
reference printer.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
