Order of parameters in cmpcov matters?

[expend20]

Hello @ifratric,

I've encountered a small problem in cmp coverage mechanics. It looks like the order of parameters does count. For example:

    cmp rcx, [rsp+0x78] ; this won't work

vs:

    cmp [rsp+0x78], rcx ; this is working

But in the first case some samples are found, so just as an assumptoin, the displacement may be calculated not accurately.

Project attached: jack_cmp.zip

UPD: just in case the parameters for the fuzzer:

fuzzer.exe -in c:\temp\in_1\ -out out -t 5000 -instrument_module test.exe -target_module test.exe -target_method FuzzIteration -nargs 1 -iterations 10000 -persist -loop -cmp_coverage -- test.exe @@

I ran your test target and confirmed it's now working correctly. Cheers!
