The LIST option specifies that the compiler should produce a pseudo-assembler listing.
.-NOLIST-. >>-+-LIST---+--------------------------------------------------><
Specifying the LIST option will increase the time and region required for a compilation. The OFFSET and MAP options may provide the information you need at much less cost.
The pseudo-assembler listing will also include at the end of the listing for each block the offset of the first instruction in that block from the start of the whole compilation unit.
