--- Comment #9 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:28ee13db2e9d995bd3728c4ff3a3545e24b39cd2 commit r15-303-g28ee13db2e9d995bd3728c4ff3a3545e24b39cd2 Author: Jakub Jelinek <ja...@redhat.com> Date: Tue May 7 21:30:21 2024 +0200 expansion: Use __trunchfbf2 calls rather than __extendhfbf2 [PR114907] The HF and BF modes have the same size/precision and neither is a subset nor superset of the other. So, using either __extendhfbf2 or __trunchfbf2 is weird. The expansion apparently emits __extendhfbf2, but on the libgcc side we apparently have __trunchfbf2 implemented. I think it is easier to switch to using what is available rather than adding new entrypoints to libgcc, even alias, because this is backportable. 2024-05-07 Jakub Jelinek <ja...@redhat.com> PR middle-end/114907 * expr.cc (convert_mode_scalar): Use trunc_optab rather than sext_optab for HF->BF conversions. * optabs-libfuncs.cc (gen_trunc_conv_libfunc): Likewise. * gcc.dg/pr114907.c: New test.
