Using Bitwise Operations on Bitfields as a Primitive SIMD

WebJan 27, 2024 · The class template bitset represents a fixed-size sequence of N bits. Bitsets can be manipulated by standard logic operators and converted to and from strings and …WebBecause "int" currently has 32 bits, if you start at one, and add a variable to itself 32 times, the one overflows and is lost completely. In assembly, there's a handy instruction "jo" (jump if overflow) to check for overflow from the previous instruction. The C++ compiler doesn't bother to use jo, though! mov edi,1 ; loop variableph stock quotes
