Are x86 assembly instructions REPE/REPZ and REPNE/REPNZ equal?
Just a quick question:
Are REPE equal to 开发者_开发百科REPZ and REPNE equal to REPNZ?
Thanks.
Yes - they are synonyms
The Intel manual volume 2B (Intel® 64 and IA-32 Architectures Software Developer's Manual
Volume 2B: Instruction Set Reference, N-Z
) says:
The REPZ and REPNZ prefixes are synonymous forms of the REPE and REPNE prefixes, respectively.)
