<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I would like to know what are the options to use with 3.3rc1 llc/opt to 32-bit (NOT 64-bit) code on a Sandy Bridge processor ?<o:p></o:p></p>
<p class="MsoNormal">I’ve defined a datalayout that use a 32-bit as pointer size and I’m passing –march=x86 to llc, is it enough ?<o:p></o:p></p>
<p class="MsoNormal">I’m not using CLANG as front-end.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks for your answer<o:p></o:p></p>
