Access register from Compiler class

[Ryan Gonzalez]

I'm writing an interpreter using AsmJit. Now, I need to add to/subtract from/etc. one of the registers. The problem: the add/sub functions in the Compiler class require GpVar variables, while I'm using GpRegs. Is there a way to solve this?

Hi Ryan,

in the case that you are using physical registers (i.e. you have your own register allocator) I think it's better to use Assembler instead of Compiler, because this way you have more control of the code generated. However, you have to understand calling conventions to do that, but I think it's not a big deal.

I'm not sure whether this was helpful, though.

Best,

Petr

To answer your question: Compiler doesn't allow to use physical registers.

Best,

Is it possible to use alloc(gpvar, rdx), for example?
