<pre wrap="">Hello,
I'm working on a change that will enable a client to build an AST from
an input file, and then, based on the contents of that AST, add
additional tokens to be parsed. Richard Smith recommended adding a
feature to the parser to do this, but it turns out that there is
something quite close already: the IncrementalProcessing option, added
in r152914.</pre>

The enclosed patch moves the IncrementalProcessing from a Preprocessor
field--which is only accessible once the preprocessor is actually
built--into the PreprocessorOptions which is available to other
interfaces which don't expose the preprocessor itself, such as the
compiler invocation.</pre>

The patch LGTM.<br>

There is only minimal testing of this feature inside
FrontendActionTest.cpp, but I have updated that as well. I will add
tests to exercise it more thoroughly once I know that this direction
is acceptable. The test itself uses two terms, calling it both
"IncrementalParsing" and "IncrementalProcessing". Not sure if that is
intentional or not.</pre>

The reason we went for IncrementalProcessing is that it does more
than just parsing, it allows clang to be able to continue working
even upon seeing an EOF token.<br>
Could you also add a test case maybe closer to your planned
use-case?<br>
Thanks,<br>
Vassil<br>
