that there is a non-weakref dependence if the quadmath functions

fortran, libgfortran: Avoid using libquadmath for glibc 2.26+ As mentioned by Joseph in PR105101, glibc 2.26 or later has on x86 (both -m32/-m64), powerpc64le, ia64 and mips support for *f128 math/complex APIs plus strtof128 and strfromf128, and these APIs allow us to avoid libquadmath for Fortran purposes on these architectures, replace *q math/complex APIs, strtof128 instead of strtoflt128 and, while strfromf128 unfortunately isn't a perfect replacement to quadmath_snprintf, it can be made to work. The advantage of this is that when configured against such glibcs (2.26 is now almost 5 years old), we can avoid linking against an extra shared library and the math support in glibc is maintained better than libquadmath. We need both a compiler change (so that for glibc 2.26+ it uses *f128 APIs instead of *q) and library change. The above mentioned problem with strfromf128 is that the strfrom* functions are severely restricted versions of snprintf. In libgfortran, we handle !isfinite differently and just use snprintf/quadmath_snprintf for %+-#.*{L,Q}{f,e} printing. strfrom* doesn't allow +, -, # modifiers and it only supports .34 or similar precision, not .* . The L/Q etc. letters are omitted. The + is there to force + sign at the start if it is positive. Workaround in the patch is to add the + at the start manually for !signbit (val). The - (left alignment instead of right) I don't understand why we need it, when minimum field width isn't specified (for strfrom* can't be specified), no padding is ever added anywhere I believe. The # is to force adding . - workaround is to search for first . or e or '\0' character, if it is '\0', just append ., if it is e, insert . before e and memmove the rest (which is just a few bytes, e, +/- and at most a few digits) one byte later. The .* case is handled by creating the format string for strfrom* by snprintf into a temporary buffer. As requested, this patch also switches from using __float128 type in libgfortran to _Float128 which is equivalent on all arches that support __float128. The change is done in a backwards compatible change, when GCC is configured against glibc 2.26 or newer, libgfortran.so.5 itself doesn't link against -lquadmath nor uses any libquadmath APIs, libgfortran.a doesn't use any libquadmath APIs either. User programs and libraries when being linked by gfortran driver are linked against -lgfortran and -lquadmath, but the latter only in the --as-needed linker mode, which means it needs to be around during linking and will be linked in if there are any calls to math/complex functions with real(kind=16) or complex(kind=16) in compilation units compiled by older versions of gcc, but if either user code doesn't call those math/complex functions for the largest supported kind, or the code is recompiled by gcc with this change in, libquadmath won't be linked in. 2022-06-28 Jakub Jelinek <jakub@redhat.com> gcc/fortran/ * gfortran.h (gfc_real_info): Add use_iec_60559 bitfield. * trans-types.h (gfc_real16_use_iec_60559): Declare. * trans-types.cc (gfc_real16_use_iec_60559): Define.
