--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
If those were added on riscv in a different version from other arches, then it
needs to conditionalize it in libstdc++-v3/config/abi/pre/gnu.ver accordingly.
CXXABI_1.3.14 {
# typeinfo for _Float{16,32,64,128,32x,64x,128x} and
# __bf16
_ZTIDF[0-9]*[_bx];
_ZTIPDF[0-9]*[_bx];
_ZTIPKDF[0-9]*[_bx];
_ZTIu6__bf16;
_ZTIPu6__bf16;
_ZTIPKu6__bf16;
} CXXABI_1.3.13;
is what it currently has, _ZTIDF[0-9]b were meant for targets with __bf16
support with the standard mangling, _ZTI*u6__bf16 with the arm mangling.
So minimal change could be to
_ZTIDF[0-9]*[_x];
_ZTIPDF[0-9]*[_x];
_ZTIPKDF[0-9]*[_x];
#ifndef __riscv
_ZTIDF[0-9]*b;
_ZTIPDF[0-9]*b;
_ZTIPKDF[0-9]*b;
#endif
_ZTIu6__bf16;
_ZTIPu6__bf16;
_ZTIPKu6__bf16;
and add CXXABI_1.3.16 with something in it just for riscv. Will defer details
to Jon or riscv maintainers.
