ISTM that we ICE here because we arrive at the assert at ipa.c:818 with:

I think two things here are interesting: that decl is WEAK, even though we're
using -fno-weak, and that DECL_INITIAL of that decl is error_mark_node. Not
sure what to do here: with the assert guarded by
if (DECL_INITIAL (node->symbol.decl) != error_mark_node)
the ICE's gone and the final assembly looks ok.
Is LTO misbehaving with -fno-weak, i.e., can it even produce a weak
FUNCTION_DECL like above?
