why does both rbp and r13 replace RM/base fiels (101) with disp32?
it would be fine if only rbp did that, why both?
everything would be encodable if r13 would treat rm/base field = 101 like r13 (rex.b set), and without rex.b as disp32.


why they made it, so i have to use reg+8 to encode r13?

Because I asked AMD to develop x64 in the way I can easily modify my 32-bit disassembler.

Why don't you ask AMD? Or why don't you ask MazeGen how his 32-bit disassembler became so instrumental in the development of X86-64?

but it has no sense!
i have to use r13+disp0 to encode r13 address!

rbp/r13 are defined to rip+disp32 is bit 0 and 1 of modrm byte are 0, regardless of REX.B !


rbp - ok, it has to be that way, but why r13 also?
rsp/12 - fine, its needed. but why do that to r13? its a WASTE of 1 byte!

amd made x64? i dont think so. i read somewere that intel sold them license to use x64 in their cpus. amd has to pay intel for making compatible cpus.

vid: Wallace & Gromit would agree with you:

Wallace and Gromit have run out of cheese and this provides an excellent excuse for the animated duo to take their holiday on the moon, where, as everyone knows, there is ample cheese.

Why is Chlorophyll green? Why do they itch? Why did it hit the Earth?

Answer all my questions and then you can. But beware, the questions are never ending.

It absorbs all other frequencies of light, something makes them itch, and a mix of gravity and chance.

Why won't it absorb green? What is "something"? What was the chance?

It reflects green, blue is high energy, and red is absorbed by other pigments, anything that makes them itch Smile, a seemingly random occurrence set in motion when the universe began.

revolution,

To keep in style, you should provide not only "why" part, but intersperse it with "this is stupid" part and occasional "I don't understand" part. Wink

grass is green because of chlorofill which absorbs red component of the light, thus the light reflected against-through a leaf into our eyes seems green.
