--- Comment #6 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Kito Cheng <k...@gcc.gnu.org>: https://gcc.gnu.org/g:e5d1f538bb7d2c7a7a4acf4a4516fa8933dc2888 commit r16-300-ge5d1f538bb7d2c7a7a4acf4a4516fa8933dc2888 Author: Kito Cheng <kito.ch...@sifive.com> Date: Tue Apr 29 11:35:00 2025 +0800 RISC-V: Allow different dynamic floating point mode to be merged [PR119832] Although we already try to set the mode needed to FRM_DYN after a function call, there are still some corner cases where both FRM_DYN and FRM_DYN_CALL may appear on incoming edges. Therefore, we use TARGET_MODE_CONFLUENCE to tell GCC that FRM_DYN, FRM_DYN_CALL, and FRM_DYN_EXIT modes are compatible. gcc/ChangeLog: PR target/119832 * config/riscv/riscv.cc (riscv_dynamic_frm_mode_p): New. (riscv_mode_confluence): New. (TARGET_MODE_CONFLUENCE): Define to riscv_mode_confluence. gcc/testsuite/ChangeLog: PR target/119832 * g++.target/riscv/pr119832.C: New test.
