--- Comment #4 from ktkachov at gcc dot gnu.org ---
So during LTO compilation inside aapcs_allocate_return_reg
the pcs_variant used is ARM_PCS_AAPCS_LOCAL (/* Private call within this
compilation unit.  */)

whereas for non-LTO it is:
ARM_PCS_AAPCS_VFP (/* Use VFP registers for floating point values.  */)
