New Revision: 308714
URL: http://llvm.org/viewvc/llvm-project?rev=308714&view=rev
Log:
Fix tblgen error.
tblgen couldn't determing a unique name between "long_call" and "far", so it
errored out when generating documentation. Copy the documentation, and give
an explicit header for "long_call".

+Clang supports the ``__attribute__((long_call))``, ``__attribute__((far))``,
+and ``__attribute__((near))`` attributes on MIPS targets. These attributes may
+only be added to function declarations and change the code generated
+by the compiler when directly calling the function. The ``near`` attribute
+allows calls to the function to be made using the ``jal`` instruction, which
+requires the function to be located in the same naturally aligned 256MB
+segment as the caller. The ``long_call`` and ``far`` attributes are synonyms
+and require the use of a different call sequence that works regardless
+of the distance between the functions.
+
+These attributes have no effect for position-independent code.
+
+These attributes take priority over command line switches such
+as ``-mlong-calls`` and ``-mno-long-calls``.
