Empty declarations "int;". Empty declarators will be pruned as well, so for example: 8 // int , a; 9 // is turned into 10 // int a; 11 // 2. Literal statements: "1.0;". The ESSL output doesn't define a default precision for float, 12 // so float literal statements would end up with no precision which is invalid ESSL. 13 // 3. Statements after discard, return, break and continue. 14 15 #ifndef COMPILER_TRANSLATOR_TREEOPS_PRUNENOOPS_H_ 16 #define COMPILER_TRANSLATOR_TREEOPS_PRUNENOOPS_H_ 17 18 #include "common/angleutils.h" 19 20 namespace sh 21 { 22 class TCompiler; 23 class TIntermBlock; 24 class TSymbolTable; 25 26 [[nodiscard]] bool PruneNoOps(TCompiler *compiler, TIntermBlock *root, TSymbolTable *symbolTable); 27 } // namespace sh 28 29 #endif // COMPILER_TRANSLATOR_TREEOPS_PRUNENOOPS_H_
