示例#1

文件： sym.cpp 项目： Fkpanov/ispc

Symbol *
SymbolTable::RandomSymbol() {
    int v = ispcRand() % variables.size();
    if (variables[v]->size() == 0)
        return NULL;
    int count = ispcRand() % variables[v]->size();
    SymbolMapType::iterator iter = variables[v]->begin();
    while (count-- > 0) {
        ++iter;
        Assert(iter != variables[v]->end());
    }
    return iter->second;
}
