Re: RFR 8239782: CC_INTERP is only used by Zero interpreter
Hi Adrian, Thank you for replying and having a look. I hope you like the patch, but if not, we'll fix it. Sorry for rushing the push. I was sitting on too many changed files.

Thanks for taking care of this! Adrian

Hi Chris, Thank you for replying! I was going to wait for Adrian but it's a big enough change that it would bit rot if I waited too long, and I didn't know how long it would be.
