   # LDS store address computation (bank-conflict-avoiding swizzle)
   # ===========================================================================
   # This section computes LDS store addresses with a swizzle pattern to avoid bank conflicts.
-  # Key outputs:
-  #   v[8]: A-tile initial store base (used only for initial stores with stride64)
-  #   V_LDS_B_ADDR (v145): B-tile store base (used for both initial and main loop)
-  #   V_LANE_DIV8_X4 (v135): (lane_id >> 3) << 2 for epilogue
-  #
   # The swizzle ensures that threads in the same wavefront write to different LDS banks.
   # Formula: swizzled_addr = base + (lane_id & 7) * LDS_A_STRIDE + swizzle_offset
   # where swizzle_offset depends on (lane_id >> 3) to distribute across banks.
