<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Several months ago, we have some discussion for Intel AMX programming model in llvm-dev. H.J. post the AMX ABI at [1], and I sent the design for the programming model at [2]. Thank
Hal, Philip for the time to review the design and provide good ideas to improve the design. After that I implemented the patch [4] and it is reviewed in LLVM community. The patch covers 6 components.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">1. The c interface to end user.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">3. The Lowering from AMX intrinsics to AMX pseudo instruction.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">4. Insert psuedo ldtilecfg and build the def-use between ldtilecfg to amx intruction.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">5. The register allocation for tile register.<o:p></o:p></p>
