If the problem is in the front-end, pretty much the only thing you can do is
preprocess the input (compile with the <tt>-E</tt> option) and send us the
results. There is no good way to reduce source-level test-cases that I know
of... if you do know, send me information and we can extend this section. :)<p>
If the problem is in the front-end, you should re-run the same
<tt>llvm-gcc</tt> command that resulted in the crash, but add the
<tt>-save-temps</tt> option. The compiler will crash again, but it
will leave behind a <tt><i>foo</i>.i</tt> file (containing preprocessed
C source code) and possibly <tt><i>foo</i>.s</tt> (containing LLVM
assembly code), for each compiled <tt><i>foo</i>.c</tt> file. Send us
the <tt><i>foo</i>.i</tt> file, along with a brief description of the
error it caused.<p>
