There is one patch from Mike to define type __ibm128 even without IEEE 128-bit floating point support, it's at the link: https://gcc.gnu.org/pipermail/gcc-patches/2022-August/599984.html I would expect this issue would be gone if the adjustment on the support of type __ibm128 gets landed in future. So maybe we can just xfail this for longdouble64? What do you think? BR, Kewen
