Level Effect
0 Code is not optimized. Provided in case other optimization levels cause
errors or interfere with debugging. Supports symbolic debugging; data is
always in memory.
1 Code is optimized within statements and across statement boundaries. The
resulting code is more efficient than that produced by lower levels of
optimization and does not interfere with debugging.
2 Code is optimized within statements and across statement boundaries, and
the resulting code is more efficient than code produced by lower levels.
Note. If your program compiles successfully at level 0 but runs out of memory at level 1 or
2, either compile your program only at level 0 or split your program into smaller
subprograms and compile those at the same higher level.
