#111786 introduced a #pragma optimize("off") to turn off optimization around _PyEval_EvalFrameDefault which seems to have side-stepped the crash. This crash was reported to the MSVC compiler team, but there hasn't been resolution around that. In the intervening time, the interpreter loop ...
qt-opensource-windows-x86-msvc2010_opengl-5.3.2.exe 去除函数的代码优化: 使用“#pragma optimize( "", off )”和“#pragma optimize( "", on )”将某(些)函数包裹起来,使得该函数 在编译生成时 不被优化 条件(这是我测试出来的,不一定全面):函数的实现不能写在类的定义里面 X...

程序员创造性地提出了许多变通方法,使问题不那么严重,例如你可以制作特殊的构建来实现一些优化而不是全部,你也可以对不同的项目使用混合优化设置,你可以使用 #pragma optimize 这样的指令来暂时禁用有问题的部分的代码的优化,但所有的这些看起来像是临时使用的补丁。让我们尝试用一个非常简单的动态数组替换我们仍然使用...
This can be reproduced with the standalone extracted testcase that is attached. The testcase contains two separate versions of an otherwise identical functiondecode_dct_coeffs, one enclosed with#pragma optimize("", off)to showcase the intended behaviour vs the misoptimization. ...
In current versions of the MSVC compiler,the /Qspectre switch only works on optimized code. You should make sure to compile your code with any of the optimization switches (e.g.,/O2or/O1but NOT/Od) to have the mitigation applied. Similarly, inspect any code that uses#pragma optimize([st...

C 复制 i = -100; t = x + y; while( i < 0 ) { i += t; } 当编译器可以假设没有别名时,循环优化会更有效,你可以使用 __restrict、noalias 或restrict 来设置别名。 备注 你可以结合使用 optimize pragma 和 g 选项,逐函数启用或禁用全局优化。有...
