WebPerformance: Even though _Bool may be theoretically as fast as unsigned int, compilers are far from being ideal, and it is likely that your compiler will miss some optimizations, which in some cases may be quite important. Web7 feb. 2024 · The compound operators (such as >>=) don't convert their arguments to int or have the result type as int. The &, , and ^ operators are also defined for operands of the bool type. For more information, see Boolean logical operators. Bitwise and shift operations never cause overflow and produce the same results in checked and unchecked contexts.

Web16 feb. 2015 · The test case doesn’t increment the int, it simply sets the counter as new value – thus the resulting numbers look different. Atomic Load is used to retrieve the value in the readers; It offers several heuristics; this test chooses the std::memory_order_consume, std::memory_order_seq_cst for setting. WebI'm not sure why this occurs - it may be due to some compiler optimization, or due to some run-time optimization which saves time on small value additions which is not present in the int code. Regardless, long is faster than int is not necessarily a safe takeaway here, as we'll see when we get into multiplication and division.
