<div id="bloop_customfont" style="margin: 0px;">
<div id="bloop_customfont" style="margin: 0px;">Hi,</div>
<div id="bloop_customfont" style="margin: 0px;"> </div>
<div id="bloop_customfont" style="margin: 0px;">I know how to write
a function pass in LLVM to iterate over function decls. I'd like to
do something similiar using Clang for C/C++/ObjC macros (#define
foo).</div>
<div id="bloop_customfont" style="margin: 0px;"> </div>
<div id="bloop_customfont" style="margin: 0px;">I haven't been able
to find anything in the docs which describes how to hook into
Clang's preprocessing phase. Did I just miss it? Are there any
samples which demonstrate this?</div>
<div id="bloop_customfont" style="margin: 0px;"> </div>
<div id="bloop_customfont" style="margin: 0px;">Thank you in
advance!</div>
</div>
