It works around the most common occurrences of the bug. 11 12 #ifndef COMPILER_TRANSLATOR_TREEOPS_GL_VECTORIZEVECTORSCALARARITHMETIC_H_ 13 #define COMPILER_TRANSLATOR_TREEOPS_GL_VECTORIZEVECTORSCALARARITHMETIC_H_ 14 15 #include "common/angleutils.h" 16 17 namespace sh 18 { 19 20 class TCompiler; 21 class TIntermBlock; 22 class TSymbolTable; 23 24 #ifdef ANGLE_ENABLE_GLSL 25 ANGLE_NO_DISCARD bool VectorizeVectorScalarArithmetic(TCompiler *compiler, 26 TIntermBlock *root, 27 TSymbolTable *symbolTable); 28 #else VectorizeVectorScalarArithmetic(TCompiler * compiler,TIntermBlock * root,TSymbolTable * symbolTable)29ANGLE_NO_DISCARD ANGLE_INLINE bool VectorizeVectorScalarArithmetic(TCompiler *compiler, 30 TIntermBlock *root, 31 TSymbolTable *symbolTable) 32 { 33 UNREACHABLE(); 34 return false; 35 } 36 #endif 37 38 } // namespace sh 39 40 #endif // COMPILER_TRANSLATOR_TREEOPS_GL_VECTORIZEVECTORSCALARARITHMETIC_H_ 41
