Controls global optimization.
#pragma optimization_level 0 | 1 | 2 | 3 | 4
This pragma specifies the degree of optimization that the global optimizer performs.
To select optimizations, use the pragma optimization_level with an argument from 0 to 4. The higher the argument, the more optimizations performed by the global optimizer.
These pragmas correspond to the settings in the Global Optimizations panel. By default, this pragma is disabled.
