--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
There is no bug here.
ICF finds that your definition of memcpy is the same as memmove and merges the
2 and then calls memcpy from your memmove and then inlines the normal memcpy
because well it says it is the same.
You can just use -fno-builtin to fix the issue by saying memcpy and memmove are
not builtins and treat them like normal functions.
That fixes the issue by not inlining the target defined memcpy.
