<p>This makefile specifies that all of the <tt>.cpp</tt> files in the current
directory are to be compiled and linked together into a
-<tt>Debug/lib/Hello.so</tt> shared object that can be dynamically loaded by
+<tt>Debug+Asserts/lib/Hello.so</tt> shared object that can be dynamically loaded by
the <tt>opt</tt> or <tt>bugpoint</tt> tools via their <tt>-load</tt> options.
If your operating system uses a suffix other than .so (such as windows or
Mac OS/X), the appropriate extension will be used.</p>
<p>Now that it's all together, compile the file with a simple "<tt>gmake</tt>"
command in the local directory and you should get a new
-"<tt>Debug/lib/Hello.so</tt> file. Note that everything in this file is
+"<tt>Debug+Asserts/lib/Hello.so</tt> file. Note that everything in this file is
contained in an anonymous namespace: this reflects the fact that passes are self
contained units that do not need external interfaces (although they can have
them) to be useful.</p>

OVERVIEW: llvm .bc -> .bc modular optimizer
USAGE: opt [options] <input bitcode>
example:</p>
<div class="doc_code"><pre>
-$ opt -load ../../../Debug/lib/Hello.so -hello -time-passes < hello.bc > /dev/null
+$ opt -load ../../../Debug+Asserts/lib/Hello.so -hello -time-passes < hello.bc > /dev/null
Hello: __main
Hello: puts
Hello: main
Lets try it out with the <tt>gcse</tt> and <tt>licm</tt> passes:</p>
<div class="doc_code"><pre>
-$ opt -load ../../../Debug/lib/Hello.so -gcse -licm --debug-pass=Structure < hello.bc > /dev/null
+$ opt -load ../../../Debug+Asserts/lib/Hello.so -gcse -licm --debug-pass=Structure < hello.bc > /dev/null

World</a> pass in between the two passes:</p>
<div class="doc_code"><pre>
-$ opt -load ../../../Debug/lib/Hello.so -gcse -hello -licm --debug-pass=Structure < hello.bc > /dev/null
+$ opt -load ../../../Debug+Asserts/lib/Hello.so -gcse -hello -licm --debug-pass=Structure < hello.bc > /dev/null

<p>Now when we run our pass, we get this output:</p>

+$ opt -load ../../../Debug+Asserts/lib/Hello.so -gcse -hello -licm --debug-pass=Structure < hello.bc > /dev/null
