stack unwinding

基本解釋

I find it convenient to focus on language features rather than on the gruesome details of vtable layout, or stack unwinding (for example).
我覺得我能夠?qū)⒆⒁饬性谡Z(yǔ)言特性本身，而不是vtable布局或者棧展開之類的可怕細(xì)節(jié)，這讓我感覺很好。
Since the compiler generates the code for stack unwinding for every C++ function, this requirement results in a larger executable and slower running code.
因?yàn)榫幾g器將為每個(gè) C++ 函數(shù)生成進(jìn)行堆展開的代碼，這種需求將導(dǎo)致更大的可執(zhí)行文件、更慢的運(yùn)行代碼。
From a control-flow perspective, an event is a function call, whereas an exception is a long jump across the stack, with unwinding semantics to destroy lost objects.
從控制流的角度看，事件是一次函數(shù)調(diào)用，而異常則是堆棧的突然跳躍，用展開的語(yǔ)義銷毀丟失的對(duì)象。
