| // PruneNoOps.h: The PruneNoOps function prunes: |
| // 1. Empty declarations "int;". Empty declarators will be pruned as well, so for example: |
| // int , a; |
| // is turned into |
| // int a; |
| // 2. Literal statements: "1.0;". The ESSL output doesn't define a default precision for float, |
| // so float literal statements would end up with no precision which is invalid ESSL. |
