C 64-bit loop performance on x86

Question

I had a similar issue like this before; I couldn't find any issues in either of our code. BUT what worked for me was changing the compiler.

My guess is that GCC is writing deprecated Assembly.

If you can decompile your application we could shed more light on the issue but there just isn't enough information to go on here.

When I decompiled my code what I found is that it was rewriting an entire method several times. but that might just be for me.

Hope this helped you, there is little to no information about this anywhere.

If I had to guess I would agree with Learner, I am pretty certain that the decompiled code would point to the for loop. I am very interested with this issue so please comment back.
