+// This pass lowers the pseudo flow control instructions (SI_IF_NZ, ELSE, ENDIF)
+// to predicated instructions.
+//
+// All flow control (except loops) is handled using predicated instructions and
+// a predicate stack.  Each Scalar ALU controls the operations of 64 Vector
+// ALUs.  The Scalar ALU can update the predicate for any of the Vector ALUs
+// by writting to the 64-bit EXEC register (each bit corresponds to a
+// single vector ALU).  Typically, for predicates, a vector ALU will write
+// to its bit of the VCC register (like EXEC VCC is 64-bits, one for each
+// Vector ALU) and then the ScalarALU will AND the VCC register with the
+// EXEC to update the predicates.
+//
+// For example:
+// %VCC = V_CMP_GT_F32 %VGPR1, %VGPR2
+// SI_IF_NZ %VCC
+//   %VGPR0 = V_ADD_F32 %VGPR0, %VGPR0
+// ELSE
+//   %VGPR0 = V_SUB_F32 %VGPR0, %VGPR0
+// ENDIF
+//
+// becomes:
+//
+// %SGPR0 = S_MOV_B64 %EXEC          // Save the current exec mask
+// %EXEC = S_AND_B64 %VCC, %EXEC     // Update the exec mask
+// S_CBRANCH_EXECZ label0            // This instruction is an
+//                                   // optimization which allows us to
+//                                   // branch if all the bits of
+//                                   // EXEC are zero.
+// %VGPR0 = V_ADD_F32 %VGPR0, %VGPR0 // Do the IF block of the branch
+//
+// label0:
+// %EXEC = S_NOT_B64 %EXEC            // Invert the exec mask for the
+//                                    // Then block.
+// %EXEC = S_AND_B64 %SGPR0, %EXEC
