--- Comment #12 from Oleg Endo <olegendo at gcc dot gnu.org> ---
This looks to be an LRA related issue (checking with GCC 10). Without -mlra it
actually compiles fine. Adding -mlra causes some issues:
sh-elf-g++ -m4 -ml -matomic-model=soft-gusa -O2 -fno-strict-aliasing
-fno-exceptions -fno-rtti -fPIC -fstack-protector-strong -std=c++17 -mlra

Vlad, maybe you have some hint where to look?
