Hi Juzhe,

LGTM apart from a tiny nit:

> +  /* We have a maximum of 11 operands for RVV instruction patterns according to
> +   * vector.md.  */
> +  insn_expander<11> e (/*OP_NUM*/ op_num, /*HAS_DEST_P*/ true,

Seems like you copied this from the non-fp ternary part but the
rest of the file uses RVV_INSN_OPERANDS_MAX already.  Could you adjust this
as well as emit_vlmax_ternary_insn?

Thanks.

Regards
 Robin

Maybe this has already been answered, but why not get the mode right in 
the expander & pattern as opposed to blindly changing it in the C fragment?

It's probably technically safe to do what you've done, mostly because by 
the time the C code runs, we've turned the scratch into a hard register 
and I suspect the code to allocate scratches probably constructs a new 
hard reg for each scratch rather than using a shared object.

But if we can, let's get the mode right from the beginning.

I'll note the existing define_insn_and_splits for integer FMAs have this 
same wart.

I failed to make Pmode of the of operand.

I have tried the following

clobber (match_dup_4)
But it causes to many issues. I do many tries turns out only the current solution can work.

Maybe this has already been answered, but why not get the mode right in 
the expander & pattern as opposed to blindly changing it in the C fragment?
 
It's probably technically safe to do what you've done, mostly because by 
the time the C code runs, we've turned the scratch into a hard register 
and I suspect the code to allocate scratches probably constructs a new 
hard reg for each scratch rather than using a shared object.
 
But if we can, let's get the mode right from the beginning.
 
I'll note the existing define_insn_and_splits for integer FMAs have this 
same wart.

Can you describe more concretely what failed?

Offhand I can't think of a reason why this shouldn't work and what 
you're doing seems long term fragile/wrong.

I have tried:

     (clobber (match_dup 4))])]
  "TARGET_VECTOR"
  {
operands[4] = gen_reg_rtx (Pmode);
})

(define_insn_and_split "*fms<VF_AUTO:mode><P:mode>"

      emit_insn (gen_rtx_SET (operands[0], operands[3]));

    DONE;
  }
  [(set_attr "type" "vfmuladd")

It fails and create ICE.

But where did ICE and *why*?  That's really the question.  Changing the 
mode just looks like papering over a more serious issue.

Hi, Jeff.

I tried again:
+(define_expand "fma<mode>4"
+  [(parallel
+    [(set (match_operand:VF_AUTO 0 "register_operand")
+	  (fma:VF_AUTO
+	    (match_operand:VF_AUTO 1 "register_operand")
+	    (match_operand:VF_AUTO 2 "register_operand")
+	    (match_operand:VF_AUTO 3 "register_operand")))
+     (clobber (match_dup 4))])]
+  "TARGET_VECTOR"
+  {
+    operands[4] = gen_reg_rtx (Pmode);
+  })
+
+(define_insn_and_split "*fma<VF_AUTO:mode><P:mode>"
+  [(set (match_operand:VF_AUTO 0 "register_operand"   "=vr, vr, ?&vr")
+	(fma:VF_AUTO
+	  (match_operand:VF_AUTO 1 "register_operand" " %0, vr,   vr")
+	  (match_operand:VF_AUTO 2 "register_operand" " vr, vr,   vr")
+	  (match_operand:VF_AUTO 3 "register_operand" " vr,  0,   vr")))
+   (clobber (match_operand:P 4 "register_operand" "=r,r,r"))]
+  "TARGET_VECTOR"
+  "#"
+  "&& reload_completed"
+  [(const_int 0)]
+  {
+    riscv_vector::emit_vlmax_vsetvl (<VF_AUTO:MODE>mode, operands[4]);
+    if (which_alternative == 2)
+      emit_insn (gen_rtx_SET (operands[0], operands[3]));
+    rtx ops[] = {operands[0], operands[1], operands[2], operands[3], operands[0]};
+    riscv_vector::emit_vlmax_fp_ternary_insn (code_for_pred_mul (PLUS, <VF_AUTO:MODE>mode),
+					      riscv_vector::RVV_TERNOP, ops, operands[4]);
+    DONE;
+  }
+  [(set_attr "type" "vfmuladd")
+   (set_attr "mode" "<VF_AUTO:MODE>")])
It seems to work and all test have passed.
Thanks for pointing this out.

I have sent V3:
https://gcc.gnu.org/pipermail/gcc-patches/2023-June/622481.html 

If this implementation is more reasonable, I will send a separate patch to adjust integer ternary autovec patterns.
