Hi,

Since Kyrill's r224367 (Restrict MAX_CONDITIONAL_EXECUTE when
-mrestrict-it is in place), gcc.target/arm/thumb-ifcvt.c fails when
testing a compiler configured to generate armv8 code by default (I
used --with-cpu=cortex-a57 for instance).

This is because -mrestrict-it is on by default for armv8-a. This patch
adds -mno-restrict-it to dg-options to remove this restriction.

The test now passes for arm-none-linux-gnueabihf --with-cpu=cortex-a57.

Ok to commit?

Thanks,

Christophe.

    * gcc.target/arm/thumb-ifcvt.c: Add -mno-restrict-it to
    dg-options.
