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. 2015-06-16 Christophe Lyon <christophe.lyon@linaro.org> * gcc.target/arm/thumb-ifcvt.c: Add -mno-restrict-it to dg-options.
