The following table lists and describes the Mid level branch optimizations options for RS08 compiler.
| Option | Description |
|---|---|
| Disable all optimizations (-Odb) | This option disables branch optimizations on the SSA form based on control flows. Label rearranging sorts all labels of the control flow to generate a minimum amount of branches. |
| Disable mid level loop hoisting (-Odb=c) | This option disables mid level loop hoisting. |
| Disable mid level branch tail merging (-Odb=b) | This option disables only branch tail merging. |
| Disable mid level label rearranging (-Odb=a) | This option disables mid level label rearranging. |
