--- Comment #32 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <[email protected]>: https://gcc.gnu.org/g:3dfd545671f0b3ffb2bd5166637381665fea7ebb commit r16-6154-g3dfd545671f0b3ffb2bd5166637381665fea7ebb Author: Richard Biener <[email protected]> Date: Mon Dec 8 10:25:21 2025 +0100 ipa/122456 - fix ICE during LTO profiledbootstrap When we have a speculated edge but we folded the call to __builtin_unreachable () then trying to update the cgraph ICEs in resolve_speculation because there's no symtab node for __builtin_unreachable (). Reject this resolving attempt similar as to when the callees decl were NULL or it were not semantically equivalent. I only have a LTRANS unit as testcase. PR ipa/122456 * cgraph.cc (cgraph_edge::resolve_speculation): Handle a NULL symtab_node::get (callee_decl).
