Hi
By accident I wrote shrx rdx,3 and uasm (V 2.55) compiled it without errors.
When debugging I saw that it was decompiled as shrx rdx,rax,r15.
I suspect something is wrong with this instruction.  :rolleyes:

it seems the same to me. Does it have consequences for your ObjAsm project?
You have to know the facts before you can distort them.

Not really, I was experimenting with a new algorithm where I wanted to use this instruction to avoid changing flags.
