Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- If at all possible, please support _Float16 regardless of the ISA, anything else is a nightmare. libgcc can have support for emulation if there is no HW support for conversions, what is more important is how the psABI decides to pass _Float16 arguments and return values and if all the supported ISAs can support such passing. If _Float16 support is added, you'd need to arrange for libstdc++ to export _ZTI{,P,PK}DF16_ symbols not in CXXABI_1.3.14 because GCC 13 didn't support those on powerpc*, but in CXXABI_1.3.17, if some options are needed tweak add_options_for_float16 etc.
