This change contains the following new commits: Git commit 5aa15abead01fef21fee4706aa01f39e8ac18829 by Douglas Yung (on behalf of Pawan Nirpal) on 16/07/2026 at 18:08.. [ARM] - Fix Thumb1InstrInfo::copyPhysReg crash on debug instructions during liveness walk. (#209478) clang asserts when compiling with -mthumb -mcpu=arm926ej-s -O0 -g (pre-v6 Thumb1, debug info enabled). The crash occurs in LiveRegUnits::stepBackward which unconditionally asserts that it must never be called on a debug instruction, but Thumb1InstrInfo::copyPhysReg walks the basic block backward without skipping DBG_VALUE instructions. Fixes: https://github.com/llvm/llvm-project/issues/209475 (cherry picked from commit 73615e792dc3116d5c66cb8175039dd6d4840f31) https://invent.kde.org/qt/clang/llvm-project/-/commit/5aa15abead01fef21fee4706aa01f39e8ac18829
