Hi @mkazantsev ,
Linaro benchmarking CI flagged this patch as increases code-size of SPEC2k6's 401.bzip2 by 3% on ARM (Thumb2 mode) and by 5% on AArch64.  This happens at -Os -flto.

Would you please check if this triggers a corner-case in your patch or something else that we can easily fix?

Thanks!
