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.)
