Thank you Jason Turner for this new episod of C++ Weekly.

If I recall correctly you can actually do the increment within the store instruction like this: "strb r1, [r0], #1"

[prahTV]

interesting technique, personally I prefer to enter assembly instructions in binary by shorting CPU pins with a screwdriver

[DamianReloaded]

Oh this is pretty cool! I'd love to see more about how you implemented the box itself. I wrote my own assemblerish compiler and it was a load of fun.

[kid-vflu]

This looks great. Can you share it via docker instead?

[esra_erimez]

I'd love to have an ARM workstation to develop on

[Hauketal]

Too bad you demonstrated the A of RGBA too early at R0 around I was waiting for the wrap-around at and the big crash. :-)

[tetsuoshiva]

Awesome! Does your c++ box support other than ARM?

I am not sure about this video. On one hand it's clearly created with good intend, but inline assembly? I personally think that this is simply the wrong way to practice assembly. Just write plain assembly without C++. I know that cpp_box doesn't support that, but I don't think this justifies demonstrating such a dangerously-easily abusable feature.

But maybe that's just me...
