<b>Subject:</b> [PATCH] Fix incorrect llvm-config output by adding support for OptionalLibrary to llvm-build<o:p></o:p></span></p>

<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please find the attached patch that addresses concerns identified by Alberto Magni in the llvm-dev thread:<o:p></o:p></p>
<p class="MsoNormal"><a href="http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-March/048521.html">http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-March/048521.html</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The patch adds a new “type” of library (in llvm-build terms) named OptionalLibrary which must be explicitly enabled (with command-line flags to llvm-build) by the build system in order to be included in the auto-generated library dependency
table used to build the llvm-config tool.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For end-users, this means the command “llvm-config –libs all” does not list libraries that are not built by the current configuration.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The proposed commit message is:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Make IntelJITEvents and OProfileJIT as optional libraries and add optional library support to the llvm-build tool:<o:p></o:p></p>
