Cmpsd instruction
Did you know?
WebAssembly - CMPS Instruction. The CMPS instruction compares two strings. This instruction compares two data items of one byte, word or doubleword, pointed to by the DS:SI and ES:DI registers and sets the flags accordingly. You can also use the conditional jump instructions along with this instruction. The following example demonstrates … WebThe CMPS, CMPSB, CMPSW, and CMPSD instructions can be preceded by the REP prefix for block comparisons of ECX bytes, words, or doublewords. More often, however, these instructions will be used in a LOOP construct that takes some action based on the setting of the status flags before the next comparison is made.
