commit r16-785-gefbc8de515c71c27e881d425f8325e39f7b4f328 Author: Richard Sandiford <richard.sandif...@arm.com> Date: Wed May 21 10:01:30 2025 +0100 genemit: Remove purported handling of location_ts gen_exp had code to handle the 'L' operand format. But this format is specifically for location_ts, which are only used in RTX_INSNs. Those should never occur in this context, where the input is always an md file rather than an __RTL function. Any hard-coded raw location value would be meaningless anyway. It seemed safer to turn this into an error rather than a gcc_unreachable. gcc/ * genemit.cc (generator::gen_exp): Raise an error if we see an 'L' operand.
