--- Comment #4 from Iain Sandoe <iains at gcc dot gnu.org> --- (In reply to Patrick Palka from comment #3) > Candidate patch: > https://gcc.gnu.org/pipermail/gcc-patches/2021-January/563000.html thanks! On Darwin, the test case now builds (checked on a 32b host [powerpc] with a 64b multilib) and a 64b (x86_64) host. The 32b multilib xfails the execute (as expected w/out int128 support) On both powerpc (64b multilib) and x86_64: test01 fails with : src-local/gcc-master/libstdc++-v3/testsuite/20_util/to_chars/long_double.cc:136: void test01(): Assertion '!strcmp(to_chars_buffer, printf_buffer+strlen("0x"))' failed. (not analysed why yet).
