This means that somewhere there is a cl_option definition that may prevail
that has size 1. lto_symtab_resolve_symbols is supposed to pick the
largest one. The cl_options definition that matters is in options.c,
created
const struct cl_option cl_options[] = { ... }
maybe it's size isn't finished?
Also
|| (DECL_SIZE (prevailing->symbol.decl) == DECL_SIZE (e->symbol.decl)
is fragile - use tree_int_cst_eq. I suppose we don't have anything
like a testcase?
