<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">There was a lightning talk at EuroLLVM about speeding up the build process. The slides and recording can be found at
<a href="http://llvm.org/devmtg/2015-04/">http://llvm.org/devmtg/2015-04/</a>, look for 'Building Clang/LLVM efficiently'.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">The talk goes into more detail but one of the bigger things you can do in the cmake build is set BUILD_SHARED_LIBS to ON.<o:p></o:p></span></p>

<div>
<p class="MsoNormal"> I'm trying to get familiar with the LLVM build procedure when adding a new Target.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal"> In the main source tree, i copied the lib/Target/MSP430 as lib/Target/newUC and renamed all the files. Further i edited the different files like Triple.h, Triple.cpp, LLVMBuild.txt, CMakeLists.txt, CallingConv.h to take in this
new Target.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal"> Then i deleted the files under the current build/ and started the LLVM build process anew.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal"> Is all of this the right way to go about this ? <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>

<p class="MsoNormal"> I expect i'll make have many issues/fixes to iterate over when modifying the files for my newTarget. Given, the build takes a long time, is there a way to do this faster ? Already been waiting 20mins for it to finish.<o:p></o:p></p>
