We have varying needs for these files. e.g., a diagnostic file is a different kind of file than compiler options which is different than attributes which is different than attribute documentation, etc. So running clang-format over .td files in Clang is not going well in practice because of how often it reformats things unlike the rest of the file. This results in a poor new contributor experience because pre-commit CI tells them the changes are not clang-format clean but we don't want the changes to be clang-format clean and so a reviewer asks them to revert and ignore pre-commit CI. >From 5d7e09d8a689e12fdce1ac6b24c10fa3accf7a45 Mon Sep 17 00:00:00 2001 From: Aaron Ballman <[email protected]> Date: Wed, 18 Feb 2026 12:40:07 -0500 Subject: [PATCH] Do not format .td files in Clang; NFC We have varying needs for these files. e.g., a diagnostic file is a different kind of file than compiler options which is different than attributes which is different than attribute documentation, etc. So running clang-format over .td files in Clang is not going well in practice because of how often it reformats things unlike the rest of the file.
