--- Comment #3 from Thomas Preud'homme <thopre01 at gcc dot gnu.org> ---
The ICE occurs because of a mismatch between the movw/movt splitter for
arm_disable_literal_pool (-mslow-flash-data) and the arm_movt instruction
pattern. The latter is guarded by -mword-relocations being disabled (via
arm_valid_symbolic_address_p) since it requires patching a 16-bit immediate but
not the former. Adding a similar check in the splitter causes relocation error
at assembly time though as GCC generate symbol+offset references instead of
doing the add as a separate instructions.
