I agree that would be less error prone. I wonder if there are cases where the old string may fail to parse so you have to do the textual upgrade first. I'm happy to make this change.

@akhuang is there a reason you used string parsing in D67631? Any objections to changing the code to parse the datalayout and add missing attributes?
