I think MSC10 is better on speed optimization, not size.
But I think also that speed gain is not so important, with modern machines, at least if you don't code a game or process-intensive applications. Mine is, but I prefere to optimize my code alone than leave it to compliler.

Ciao

ok. What the purpose of the cpuid call? The results are not used anywhere or so it seems.

It resets che processor cache. It's needed because you're rewriting the code.

I do have many problems with my customers of dumb antivirus reporting my code as suspect or, whorse, as a trojan.
I think that antivirus producers should be sued because of this. They made me loose a couple of customers with their dumb behaviour.

I read up a bit on the topic, and the conclusion is that if you sign the executable (after cryping it) with a valid code certificate then the number of false positives will greatly reduce.
The Microsoft signtool is already included with the compiler.
The certificate costs about 180 euros a year.

Thank you, but I absolutely refuse to pay money because of other people's mistakes.
180 Euro for a certificate to be able to sell MY application because of bullshit antivirus ? NEVER.

I hear ya. I'm still considering it.
If it prevents 1 client from running away then it's worth it for me.
