That is not a bad solution if it works for you, because you can use only<br>
some standard tools already available on any systems, such as objdump or<br>
gdb with a script...<br></blockquote><div> </div><div>It's the solution that gets closest to want I want to achieve so far. But it's not pretty :-) It also doesn't contain the whitespace and comment data (see below) which would be useful.</div>

<br>
In the "other tools" family, gcc-xml can output the AST in an XML way.<br>

<div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">In our Par4All compiler, we use another tool internally, PIPS, that<br>
allows to output the AST in HTML or in a textual format.<br>
<br>
There is a web service you can use to have an idea of what it can output:<br>

<div>1. Is it possible to output file line number and character position so that it is also part of the tree?</div><div>2. Is it possible for the tree to contain info relating to whitespace and comments?</div><div><br></div>
<div>Ideally I'd like to be able to use a tool like PIPS to do so-called round trip parsing where the original source code can be rebuilt exactly from the intermediate representation. Somewhat like what this Perl module achieves:</div>
