Hi,

I'm surprised to see many new errors on arm after the backport for PR98722
See: https://people.linaro.org/~christophe.lyon/cross-validation/gcc/gcc-10/r10-9881-g1791b11d9cae388ae18a768eeb96c998439c986a/report-build-info.html

Przemyslaw, Vladimir do you confirm r10-9881 has no such errors (new
ICEs) on your side?

Thanks
