Hi, Josef<div><br></div><div> I just went through this process several weeks ago. Those tutorials are too old to suit new revisions of Clang.</div><div> Attached is an simple (runnable) program to experiment the uninitialized variables analysis (implemented in tools/clang/lib/Analysis/UninitializedValues.cpp). </div>
<div> Hope this helps.</div><div><br></div><div>-----</div><div>Guoping<br><br><div class="gmail_quote">2011/10/11 josef maxim pohl <span dir="ltr"><<a href="mailto:josef.m.pohl@gmail.com">josef.m.pohl@gmail.com</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Hi there,<br><br>I have been banging my head against clang for a bit now
trying to get a sense of how a few things work. Hence I have a
complete beginner type question. <br><br>I am simply trying to construct an AST which I can use to do some source transformations. <br>
In trying to work through some of the examples and older tutorials I
have noticed that many use a preprocessor instance. With the recent
version of clang there seems to be a fundamental difference in the way a
preprocessor object is constructed. My first question is can anyone
tell me how to reconcile the old methodology with the new. (ie does
anyone have a decent example of this.) <br>
<br>The other approach to constructing an AST, it appears, is through
the construction of a CompilerInstance. However I have only seen this
used in plugin operations or in examples that are not constructing an
AST. Are there any good examples of this behavior (operation) in a stand
alone application? <br>
<br>Please feel free to correct my misguided notions of what is going on and I apologize for the complete beginner questions.<br>Thanks<br><font color="#888888">Josef<br>
