commit r16-7112-g974182ec0985dfce4960d07cae5f28ae2f70874e Author: Richard Biener <[email protected]> Date: Wed Jan 28 10:16:29 2026 +0100 rtl-optimization/106859 - fix location dumping from var-tracking We currently ICE when the locations include one without a setting insn. Looking at cselib this seems to be a supported state so the following arranges for this and dumps -1 as UID. PR rtl-optimization/106859 * var-tracking.cc (val_store): Dump -1 as UID if setting_insn is NULL.
