Ping?
I'm OK with backporting it if a release manager approves it.

The patch (in r215101) can be backported without any change on 4.8 and 4.9 branches. I checked in QEMU with and without the patch on both branches and it indeed solves the problem. Testsuite run without regression when compiled with arm-none-eabi cross compiler and executed on QEMU emulating Cortex-M3. I also bootstrapped gcc on x86_64-linux-gnu and run the testsuite without regressions. Is it ok for backport? Best regards, Thomas
