--- Comment #3 from Sergei Trofimovich <slyfox at gcc dot gnu.org> ---
Hm, mpfr-4.1.0 still fails these 2 tests for me from current gcc-master.

Comparing -O2 build from last week and this week snapshot code generation
changed seemingly only for `mpfr_get_decimal64()` at src/.libs/get_d64.o.

I'll re-check current gcc-master, extract self-contained example from
mpfr-4.1.0 and reopen the bug if I succeed.
