two byte variable handled as one short block

[em-eight]

Hello,

I'm using ghidra with an architecture that contains some aliasing between registers. Simply put, it has 8-bit registers that alias with 16-bit registers.

The issue is sometimes this causes computation to happen in 16-bit register with ugly concat pcode, when in reality it was just two 8-bit variables.

Example:

Here uVar5 should have been split into two u8 variables.

Is there anything I can do to fix this?

Have you tried to manually set uVar5 as byte[2] or a struct containing 2 bytes?

That does get rid of the CONCAT but still no separate variable
