Hi,
We hit an ICE using lto with neon intrinsics that could be traced back
to an invalid call to convert during expand with LTO . Fixed by
backporting Richi's fix from mainline - checking he had no objections
to this on IRC , tested cross on arm-linux-gnueabi with qemu for no
regressions.
Applied to the FSF 4.7 branch.
regards,
Ramana

* config/arm/arm.c (neon_dereference_pointer): Do not call
covert during RTL expansion.
