Jakub Jelinek 0d973c0a0d openmp: Implement the error directive
This patch implements the error directive.  Depending on clauses it is either
a compile time diagnostics (in that case diagnosed right away) or runtime
diagnostics (libgomp API call that diagnoses at runtime), and either fatal
or warning (error or warning at compile time or fatal error vs. error at
runtime) and either has no message or user supplied message (this kind of
e.g. deprecated attribute).  The directive is also stand-alone directive
when at runtime while utility (thus disappears from the IL as if it wasn't
there for parsing like nothing directive) at compile time.

There are some clarifications in the works ATM, so this patch doesn't yet
require that for compile time diagnostics the user message must be a constant
string literal, there are uncertainities on what exactly is valid argument
of message clause (whether just const char * type, convertible to const char *,
qualified/unqualified const char * or char * or what else) and what to do
in templates.  Currently even in templates it is diagnosed right away for
compile time diagnostics, if we'll need to substitute it, we'd need to queue
something into the IL, have pt.c handle it and diagnose only later.

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.
