WebTo accomplish this far jump, use the following two instructions: JNZ BEYOND; JMP FARLABEL; BEYOND: The JRCXZ, JECXZ and JCXZ instructions differ from other J cc instructions because they do not check status flags. Instead, they check RCX, ECX or CX for 0. The register checked is determined by the address-size attribute. WebBit manipulation instructions sets (BMI sets) are extensions to the x86 instruction set architecture for microprocessors from Intel and AMD.The purpose of these instruction sets is to improve the speed of bit manipulation.All the instructions in these sets are non-SIMD and operate only on general-purpose registers.There are two sets published by Intel: …
