Comment at: llvm/lib/Target/X86/X86LowerAMXIntrinsics.cpp:318-319
+    // calculate idxa, idxb, idxc
+    // %eltc = extractelement <256 x i32> %vec.c.inner.phi, i16 %idxc
+    // %eltcf32 = bitcast i32 %eltc to float
+    // %elta = extractelement <256 x i32> %veca, i16 %idxa

In fact, we are trying to find a bitcast whose operand is <256 x i32>, as shown in line229.
