MTC added a comment. Thank you for your review, @NoQ!
- `isBooleanType()` is used to check `_Bool` in C99/C11 and `bool` in C++. For `_Bool` , there is the same overflow problem. - In C++98/C++11/C++14, for `++bool` and `bool+`, both sets true directly. - In C++, `--bool` and `bool--` is illeagal. - In C99/C11 standard, there is not much information about `_Bool++` and `_Bool--`. From the implementation of the compiler, `_Bool++` and `_Bool--` are divided into the following situations. - _Bool b = 0; b++; // b -> 1 - _Bool b = 1; b++; // b -> 1 - _Bool b = 0; b--; // b -> 1 - _Bool b = 1; b--; // b -> 0 So it's reasonable to set to true if the operand of the increment operator is of type _Bool, just my opinion. I not familiar with Objective-C++, can you provide a appropriate test about Objective-C++ for me, thank you! And I'm not a native speaker of English, the grammar of the comments may not be correct. If so, please correct me, thanks!
