在以前版本的编译器中,此示例底部的静态断言可传递,因为 std::is_convertable<>::value 错误地设置为 true。 现在,std::is_convertable<>::value 正确设置为 false,使静态断言失败。 默认设置或已删除的日常复制和移动构造函数遵从访问说明符 对于默认设置或已删除的日常复制和移动构造函数的

The primary reason for this note, however, is to get it fresh in peoples mind that as we use gcc more if nothing else, to create PIC libc.a) we'll have to be careful about that. (An easy way out of this is to declare the string as a static char[] initialized to that value.)...
The value is either yes or no. If yes, all variables will be aligned on 8-byte boundaries. Default is -dbl_align_all=no. When compiling for 64-bit environments with -xarch=v9 or v9a, this flag will align quad-precision data on 16-byte boundaries. ...
If you wish to override the default value, implement the carousel:valueForOption:withDefault: delegate method and return a value for iCarouselOptionWrap. @property (nonatomic, assign, getter = isPagingEnabled) BOOL pagingEnabled; Enables and disables paging. When paging is enabled, the carousel...
gcollapse (nansum)andgcollapse (rawnansum)outputs a missing value for sums if all inputs are missing (instead of 0). gcollapse, mergemerges the collapsed data set back into memory. This is much faster than collapsing a dataset, saving, and merging after. However, Stata'smerge ..., upd...
This value is the bitwise "or" of all the accrued exception flags, where each flag is represented by a single bit as shown in TABLE 4-3. The positions of the bits corresponding to each exception are given by the fp_exception_type values defined in the file sys/ieeefp.h. (Note that ...
