For non-LTO binds_local_p says no to memcpy, for LTO it says yes.
else if (TREE_CODE (exp) == FUNCTION_DECL && TREE_PUBLIC (exp))
{
struct cgraph_node *node = cgraph_get_node (exp);
if (node
&& resolution_local_p (node->symbol.resolution))
resolved_locally = true;
makes the difference because we have a resolution recorded (resoved_ir) and
that makes us skip
/* Variables defined outside this object might not be local. */
else if (DECL_EXTERNAL (exp) && !resolved_locally)
local_p = false;
and fall into
/* If defined in this object and visibility is not default, must be
local. */
else if (DECL_VISIBILITY (exp) != VISIBILITY_DEFAULT)
local_p = true;
which says "defined in this object" but doesn't check that (well,
the resolution is wrong).
The resolutions from the linker are just
2
t1.o 1
165 beb4fef7e77e8790 PREVAILING_DEF_IRONLY foo
t2.o 1
165 6eae315f149cc09b PREVAILING_DEF_IRONLY bar
but lto_symtab_resolve_symbols assigns LDPR_RESOLVED_IR :(
