Title: optimizing assembly code
Post by: juliomacedo on January 17, 2006, 04:09:46 PM

Where can I find about optimization of assembly code?

I want to find a source of tips as:

Using DEC and JZ is faster than using LOOP...

Using SHL when multiplying for a power of two is a faster way of doing that...

Thanks

Julio
