3. Use std::array or std::vector function In C++, the standard approach is to use the std::array container to encapsulate fixed-size arrays. Unlike a C-style array, it doesn’t decay to a pointer automatically and can be passed to a function by value. We can also use the std::vec...
AMDGPU后端中的AMDGPUPromoteAllocaToVector pass就是一个function pass。这个pass通过将Alloc指令转换为向量消除Alloc指令: classAMDGPUPromoteAllocaToVector:publicFunctionPass{……boolrunOnFunction(Function&F)override;……boolhandleAlloca(AllocaInst&I);voidgetAnalysisUsage(AnalysisUsage&AU)constoverride{AU.setPres...
Expected Behavior I can pass std::vector<int32_t>, but the the c++ library I want to use uses int, not int32_t std::vector<int> build_array() { auto values = std::vector<int> {1,2,3,4,5}; for (auto& v: values) v = v * 2; return values; }...
Pass By Reference In the examples from the previous page, we used normal variables when we passed parameters to a function. You can also pass areferenceto the function. This can be useful when you need to change the value of the arguments:...
real function foo(a, b) !dir$ attributes vector :: foo implicit none real, intent(in) :: a, b foo = a + b end function foo The above function has restrictions on it (see User and Reference Guide). The example above is likely to pass a, and b by value in SIMD registers (4...

// if (toObfuscate(flag, tmp, "fla")) { if (flatten(tmp)) { ++Flattened; } // } return false; } 首先运行的是runOnFunction,因为我是在源码树外开发的Pass所以把原版的参数判断代码注释了,主要调用了faltten函数。 vector<BasicBlock *> ...
Where g is some function. I'm not sure if theintegralfunction is handling it correctly, because if it passes a vectort, the sum will not iterate over the correct range. I would really appreciate any insights! Thanks! 채택...
所有FunctionPass在程序中的每个方法上执行,独立于程序中的所有其它方法。 FunctionPass子类不需要以特定顺序执行,并且不会修改外部方法。 明确地说,FunctionPass子类不允许检查或修改当前正在处理的方法以外的其它方法,也不允许添加或删除当前模块的方法和全局变量。AMDGPU后端中的AMDGPUPromoteAllocaToVector pass就是一个...
