alexcrichton opened PR #5906 from x64-shr to main:

This catches a case that wasn't handled previously by #5880 to allow a constant load to be folded into an instruction rather than forcing it to be loaded into a temporary register.

Interesting that this isn't 0x7 but maybe the printer doesn't care because it doesn't really matter?

I'm assuming these were here for padding and the removal of the instruction changes the offsets enough that the padding is unnecessary.
