- * \file opt_copy_propagation_elements.cpp

- * Replaces usage of recently-copied components of variables with the
- * previous copy of the variable.
- *
- * This pass can be compared with opt_copy_propagation, which operands
- * on arbitrary whole-variable copies. However, in order to handle
- * the copy propagation of swizzled variables or writemasked writes,
- * we want to track things on a channel-wise basis. I found that
- * trying to mix the swizzled/writemasked support here with the
- * whole-variable stuff in opt_copy_propagation.cpp just made a mess,
- * so this is separate despite the ACP handling being somewhat
- * similar.
- *
- * This should reduce the number of MOV instructions in the generated
- * programs unless copy propagation is also done on the LIR, and may
- * help anyway by triggering other optimizations that live in the HIR.
