--- Comment #36 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:69ffddd8bd9947c5c060979e453d6b138ad3ed8c commit r15-9476-g69ffddd8bd9947c5c060979e453d6b138ad3ed8c Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Apr 15 07:55:55 2025 +0200 libgcobol: Handle long double as an alternate IEEE754 quad [PR119244] I think there should be consistency in what we use, so like libgcobol-fp.h specifies, IEEE quad long double should have highest priority, then _Float128 with *f128 APIs, then libquadmath. And when we decide to use say long double, we shouldn't mix that with strfromf128/strtof128. Additionally, given that the *l vs. *f128 vs. *q API decision is done solely in libgcobol and not in the compiler (which is different from the Fortran case where compiled code emits say sinq or sinf128 calls), I think libgcobol.spec should only have -lquadmath in any form only in the case when using libquadmath for everything. In the Fortran case it is for backwards compatibility purposes, if something has been compiled with older gfortran which used say sinq and link is done by gfortran which has been configured against new glibc with *f128, linking would fail otherwise. 2025-04-15 Jakub Jelinek <ja...@redhat.com> Rainer Orth <r...@cebitec.uni-bielefeld.de> PR cobol/119244 * acinclude.m4 (LIBGCOBOL_CHECK_FLOAT128): Ensure libgcob_cv_have_float128 is not yes on targets with IEEE quad long double. Don't check for --as-needed nor set LIBQUADSPEC on targets which USE_IEC_60559. * libgcobol-fp.h (FP128_FMT, strtofp128, strfromfp128): Define. * intrinsic.cc (strtof128): Don't redefine. (WEIRD_TRANSCENDENT_RETURN_VALUE): Use GCOB_FP128_LITERAL macro. (__gg__numval_f): Use strtofp128 instead of strtof128. * libgcobol.cc (strtof128): Don't redefine. (format_for_display_internal): Use strfromfp128 instead of strfromf128 or quadmath_snprintf and use FP128_FMT in the format string. (get_float128, __gg__compare_2, __gg__move, __gg__move_literala): Use strtofp128 instead of strtof128. * configure: Regenerate.
