you might try <tt>llvm-link -v</tt> on the same set of input files. If
that also crashes, you may be experiencing a linker bug.
-<li>If your program is <b>supposed</b> to crash, <tt>bugpoint</tt> will be
- confused. One way to deal with this is to cause bugpoint to ignore the exit
- code from your program, by giving it the <tt>-check-exit-code=false</tt>
- option.
-
<li><tt>bugpoint</tt> is useful for proactively finding bugs in LLVM.
Invoking <tt>bugpoint</tt> with the <tt>-find-bugs</tt> option will cause
the list of specified optimizations to be randomized and applied to the
program. This process will repeat until a bug is found or the user
kills <tt>bugpoint</tt>.
+
+<li><p><tt>bugpoint</tt> does not understand the <tt>-O</tt> option
+ that is used to specify optimization level to <tt>opt</tt>. You
+ can use e.g.</p>
+
+<div class="doc_code">
+<p><tt>opt -O2 -debug-pass=Arguments foo.bc -disable-output</tt></p>
+</div>
+
+ <p>to get a list of passes that are used with <tt>-O2</tt> and
+ then pass this list to <tt>bugpoint</tt>.</p>
