is it possible to make jump tables inside __asm blocks?

 

[refraction]

very much doubt it, if it is possible, it'd be very hard.

altho its possbile to use asm blocks FROM a jump table

 

[cufunha]

can I even create a jump table and call it from inside an __asm block?
PS: how do I make a jump table? is it possible to get the labels addresses into a c++ array?

 

[refraction]

its explained in a good tutorial HERE by zenogais, should explain what you need to know about jump tables

 

[cufunha]

it's not a jump table, it's a tutorial on function pointers, with is a little diferent.

No, it's a jump table. A jump table is basically an array with function pointers.

I'm working on some similar stuff in my interpreter right now, and there is a way to have an array of jump labels (kind of).

aLabel:

//do something

Now, to copy this label into a variable:

void* jmpPtr;
__asm mov EAX, aLabel
__asm mov jmpPtr, EAX

Of course, you can then put these jump pointers into an array. That's the way I do it anyway. (Note, you don't have to use the EAX register, any 32-bit general purpose register should do.)
