--- Comment #1 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Ilya Leoshkevich <i...@gcc.gnu.org>: https://gcc.gnu.org/g:b6e446cb58183557a5a5d87dc866aae9613544f8 commit r11-7310-gb6e446cb58183557a5a5d87dc866aae9613544f8 Author: Ilya Leoshkevich <i...@linux.ibm.com> Date: Wed Feb 17 14:40:03 2021 +0100 IBM Z: Fix long double <-> DFP conversions When switching the s390 backend to store long doubles in vector registers, the patterns for long double <-> DFP conversions were forgotten. This did not cause observable problems so far, because libdfp calls are emitted instead of pfpo. However, when building libdfp itself, this leads to infinite recursion. gcc/ChangeLog: PR target/99134 * config/s390/vector.md (trunctf<DFP_ALL:mode>2_vr): New pattern.
