Question about the detailed mem_read instructions of instruction mix in MICA #25

Open WilliamWangPeng opened 2 years ago

WilliamWangPeng commented 2 years ago

Hello dear author,

It's my great honor to write a letter to you, I'm reading two articles[1][2] about mem_read instructions of instruction mix in MICA, I want to know the detailed mem_read instructions of instruction mix. Because x86 exists some arithmetic instructions of memory operands, which belongs to mem_read or arithmetic type ?

I have also searched on MICA github[3], but still can't find the answer.

[1]"Comparing Benchmarks Using Key Microarchitecture-Independent Characteristics"

[2]" MICROARCHITECTURE-INDEPENDENT WORKLOAD CHARACTERIZATION"

thank you

best regards

William

Hi,

You can find detailed implementation of ILP instructions, including mem_read and write here: https://github.com/boegel/MICA/blob/master/mica_itypes.cpp

MICA is only a plugin for PIN. You need to refer to PIN manual: https://software.intel.com/sites/landingpage/pintool/docs/98579/Pin/doc/html/index.html

thank you dear @amirjamez I have found five indexes about "memory operand", which shows
"// Note that in some architectures a single memory operand can be both read and written (for instance incl (%eax) on IA-32) In that case we instrument it once for read and once for write" in the picture below. Does that mean some arithmetic instructions of memory operands belongs to mem_read type ?

thank you so much best regards with kindness William

Yes. I believe so.
