commit r12-10453-g1f41e8eef3da1d76c18fe1a93846054c53dc5a47 Author: Richard Biener <rguent...@suse.de> Date: Mon Jan 22 15:42:59 2024 +0100 debug/112718 - reset all type units with -ffat-lto-objects When mixing -flto, -ffat-lto-objects and -fdebug-type-section we fail to reset all type units after early output resulting in an ICE when attempting to add then duplicate sibling attributes. PR debug/112718 * dwarf2out.cc (dwarf2out_finish): Reset all type units for the fat part of an LTO compile. * gcc.dg/debug/pr112718.c: New testcase.
