Hello, when i used clang for matrix multiplication code with i=j=k=1000351, it successfully generates IR. then i run opt as follows opt -S -O3 -force-vector-width=64 -force-vector-interleave=32 matn.ll -o pimmatnl_64_u32_o3.ll it also worked fine. but when i run llc on the optimized .ll file llc -x86-asm-syntax=intel pimmatnl_64_u32_o3.ll -o matnl-knl4_intel.s i get t...
