commit 9b813c320ee59176e3279391ef7c47ef6ea8ba3a Author: Michael Meissner <meiss...@linux.ibm.com> Date: Tue Apr 9 00:30:46 2024 -0400 Add power10 ori/oris and xori/xoris fusion support. 2024-04-09 Michael Meissner <meiss...@linux.ibm.com> gcc/ * config/rs6000/fusion.md: Regenerate. * config/rs6000/genfusion.md (gen_wide_immediate): Add wide immediate fusion patterns. * config/rs6000/rs6000.md (IORXOR_OP): New code attribute. (ior, xor splitter): Do not split ior/xor patterns that could be fused on power10.
