I was looking at the <span class="comment">intrinsic creation methods of the IRBuilder, but I can only find functions corresponding to memset, memcpy and memmove intrinsics, not for prefetching.</span></div><div style="color: rgb(0, 0, 0); font-size: 13.3333px; font-family: arial,helvetica,sans-serif; background-color: transparent; font-style: normal;"><span class="comment"><br></span></div><div style="color: rgb(0, 0, 0); font-size: 13.3333px; font-family: arial,helvetica,sans-serif; background-color: transparent; font-style: normal;"><span class="comment">Also, I target x86-64
architectures. Is it sufficient to insert a call to the intrinsic in the LLVM IR to have the corresponding prefetch instruction generated for this target?<br></span></div><div style="color: rgb(0, 0, 0); font-size: 13.3333px; font-family: arial,helvetica,sans-serif; background-color: transparent; font-style: normal;"><br><span class="comment"></span></div><div style="color: rgb(0, 0, 0); font-size: 13.3333px; font-family: arial,helvetica,sans-serif; background-color: transparent; font-style: normal;"><span class="comment">Thank you for your help,</span></div><div style="color: rgb(0, 0, 0); font-size: 13.3333px; font-family: arial,helvetica,sans-serif; background-color: transparent; font-style: normal;"><span class="comment">Alexandra<br></span></div></div></body></html>
