It *is* supported, per discussion at https://gcc.gnu.org/pipermail/gcc-patches/2023-November/638760.html. But then you should use "../configure", not "../gcc/configure". Running the configure script of a GCC component (instead of the top-level configure) directly is completely unsupported. -- Xi Ruoyao <xry...@xry111.site> School of Aerospace Science and Technology, Xidian University
