PR fortran/46625 * quadmath.map (QUADMATH_1.0): Remove quadmath_strtopQ and quadmath_dtoaq. Add strtoflt128 and quadmath_flt128tostr. * quadmath_weak.h (quadmath_strtopQ, quadmath_dtoaq): Remove. (strtoflt128, quadmath_flt128tostr): Add. * gdtoa/strtopQ.c (quadmath_strtopQ): Rename to... (strtoflt128): ... this. Return __float128, instead of writing to memory pointed by last argument. * quadmath.h: Use C style comments instead of C++ style. (quadmath_strtopQ, quadmath_dtoaq): Remove prototypes. (strtoflt128, quadmath_flt128tostr): Add prototypes. * libquadmath.texi (quadmath_dtoaq): Rename to quadmath_flt128tostr. (quadmath_strtopQ): Rename to strtoflt128. Adjust prototype, adjust examples. * quadmath_io.c (quadmath_dtoaq): Rename to... (quadmath_flt128tostr): ... this. libgfortran/ * io/write_float.def (DTOAQ): Use quadmath_flt128tostr instead of quadmath_dtoa. * io/transfer128.c (tmp1, tmp2): New variables, bring in strtoflt128 and quadmath_flt128tostr. (transfer_real128, transfer_real128_write, transfer_complex128, transfer_complex128_write): Remove tmp1/tmp2 variables. * io/read.c (convert_real): Use strtoflt128 instead of quadmath_strtopQ, adjust for the changed arguments and return value.
