Wow!
FASM can interpret [REG*5] as [reg + reg*4]??!!
Very cool! Can MASM do that?

It is OK -- I was just asking to get some knowledge on it.
I like information!

revolution: You're right. We should concentrate on what needs to be optimized, consider how often it occurs and use a profiler (or cpuid+rdtsc) to determine critical sections of code. All too often, programmers try to optimize everything equally and they end up wasting time with initiation code that only occurs once or calling and general program flow. Example:

Code:

; It would be foolish to optimize this division because the
; call following it takes 100,000s of times longer

idiv ecx
call draw.complex.imagery ; < 5 million CPU cycles

just another way.

Code:

lea r32_dest,[r32_src*5]
lea r32_dest,[r32_dest*2]

or if only on 1 byte

Code:

I all I want is just to be able to see my registers. Is that too much to ask? Like the level of trash talk on this forum is just toxic, its not even funny. I've read 3 threads and every single one of them had trash talk in it. Why are you attacking people over programming?Why is this even allowed on the site? Seriously, swallow your pride and just help people. ._.
