This seemingly got reverted in classic codegen? I leave a version of the TODO in place since I suspect we'll see it agian. >From b578b466fc75913209390fc1c71370bacf6ca15c Mon Sep 17 00:00:00 2001 From: erichkeane <[email protected]> Date: Fri, 28 Aug 2026 07:38:09 -0700 Subject: [PATCH] [CIR] Fix ptrdiff tests (ptrtoint/ptrtoaddr) This seemingly got reverted in classic codegen?
