C++ 包含5个以上参数的rope表达模板未能正确内联
我尝试了一些表达性模板和rope数据结构，尝试看看可以获得什么样的收益。到目前为止，它运行得很好。但是，当试图将5个以上的参数连接在一起时，编译器无法正确优化并生成不必要的临时参数。有人能告诉我为什么会这样吗？这是编译器限制还是我的优化选项需要调整 我正在使用g++4.4.1（mingw32）和以下选项：-O3-Winline-Wextra-Wall-fno异常-fno rtti-fomit帧指针-feexpensive优化-fverbose asm-S 代码如下所示，这只是一个实验，因此它并不真正遵循任何标准：C++ 包含5个以上参数的rope表达模板未能正确内联,c++,templates,optimization,C++,Templates,Optimization,我尝试了一些表达性模板和rope数据结构，尝试看看可以获得什么样的收益。到目前为止，它运行得很好。但是，当试图将5个以上的参数连接在一起时，编译器无法正确优化并生成不必要的临时参数。有人能告诉我为什么会这样吗？这是编译器限制还是我的优化选项需要调整 我正在使用g++4.4.1（mingw32）和以下选项：-O3-Winline-Wextra-Wall-fno异常-fno rtti-fomit帧指针-feexpensive优化-fverbose asm-S 代码如下所示，这只是一个实验，因此它并不
