- Subject: [Patch ARM 4_7-branch ] Backport fix for flto failure with neon intrinsics.
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.
