In C++, which is better i>-1 or i>=0

This might be a silly question to ask, but this kind of optimization is sometimes boost performance of your application. Here I am asking specifically for C++, because the way C++ compile code is a lot different that c# or Java.

The question is which one performs better, if variable i is int.

1. i > -1
2. i >= 0

I am looking for performance in terms of memory block or registers required and CPU cycles required for both conditions.

Thanks in advance.

In assembly language, both are on the same structure:

1. i > -1

   cmp   [register with i value],-1
   jg    [somewhere]
   

2. i >= 0

   cmp   [register with i value],0
   jge   [somewhere]
   

According to used jump flags, the instruction jg make two flags comparaisons (ZF = 0 and SF = OF) but jge does only one (SF = OF).

So I'm tempted to say that both use almost same registers and CPU cycles, with maybe a very little quicker comparaison for i >= 0.
