  "message": "[PATCH] RISC-V: Fix missing return in expand_vec_perm\n\nIn expand_vec_perm, the branch handling a selector that is a constant\nduplicate (all indices identical) emits a VLMAX vrgather and is then\nmeant to be done.  The missing return let control fall through into the\ngeneric modulo-index handling below, which recomputes and overwrites\nthe target with another gather sequence.\n\nAdd the return so the duplicate path stops after the gather.\n\nNo test case is added: without the return the first gather is a dead\nstore to the target that the generic path immediately overwrites, so it\nis removed by later RTL dead-store elimination and the final assembly is\nidentical with and without the fix.  No test can therefore observe the\nchange.\n\ngcc/ChangeLog:\n\n\t* config/riscv/riscv-v.cc (expand_vec_perm): Add missing return\n\tafter emit_vlmax_gather_insn.\n",
