The following patch adds the compiler and library side of -mabi=ieeelongdouble I/O support. 2022-01-04 Jakub Jelinek <jakub@redhat.com> gcc/fortran/ * trans-io.c (transfer_namelist_element): Use gfc_type_abi_kind, formatting fixes. (transfer_expr): Use gfc_type_abi_kind, use *REAL128* APIs even for abi_kind == 17. libgfortran/ * libgfortran.h (__acoshieee128, __acosieee128, __asinhieee128, __asinieee128, __atan2ieee128, __atanhieee128, __atanieee128, __coshieee128, __cosieee128, __erfieee128, __expieee128, __fabsieee128, __jnieee128, __log10ieee128, __logieee128, __powieee128, __sinhieee128, __sinieee128, __sqrtieee128, __tanhieee128, __tanieee128, __ynieee128): Formatting fixes. (__strtoieee128, __snprintfieee128): Declare. * io/io.h (default_width_for_float, default_precision_for_float): Handle kind == 17. * io/size_from_kind.c (size_from_real_kind, size_from_complex_kind): Likewise. * io/read.c (set_integer, si_max, convert_real, convert_infnan, read_f): Likewise. * io/write.c (extract_uint, size_from_kind, set_fnode_default): Likewise. * io/write_float.def (DTOA2Q, FDTOA2Q): Define for HAVE_GFC_REAL_17. (determine_en_precision, get_float_string): Handle kind == 17. * io/transfer128.c: Use also for HAVE_GFC_REAL_17, but don't drag in libquadmath if POWER_IEEE128. * Makefile.am (comma, PREPROCESS): New variables. (gfortran.ver): New goal. (version_arg, version_dep): Use gfortran.ver instead of $(srcdir)/gfortran.map. (gfortran.map-sun): Depend on and use gfortran.ver instead of $(srcdir)/gfortran.map. (BUILT_SOURCES): Add $(version_dep). * Makefile.in: Regenerated. * gfortran.map (GFORTRAN_8): Don't export _gfortran_transfer_complex128, _gfortran_transfer_complex128_write, _gfortran_transfer_real128 and _gfortran_transfer_real128_write if HAVE_GFC_REAL_17 is defined. (GFORTRAN_12): Export those here instead.
