OK, it's reasonable.

 

Thanks,

Hi Hao,

 

GenOpString() is only used to generate function body, but here I want to
modified the function's argument name, like switching vcopy_lane(a, b, c) to
vcopy_lane(a1, b1, c1).

Hi Kevin,

There are two points of hard code in shared functions:

+    //To avoid argument being multiple defined, add extra number for
renaming.
+    if (name == "vcopy_lane")
+      s.push_back('1');

+    bool extranumber = false;
+    if(name == "vcopy_lane")
+      extranumber = true;

     s += TypeString(proto[i], typestr) + " __";
     s.push_back(arg);
+    if(extranumber)
+      s.push_back('1');
     s += " = (";
     s.push_back(arg);
+    if(extranumber)
+      s.push_back('1');


I think maybe this is not necessary. Because you can achieve renaming in
function GenOpString(name, op, proto, typestr).
As this function has passed the "name", you can handle renaming under the
switch case of OpCopy like:

case OpCopy: {
    if (name == "vcopy_lane") {
        renaming ....

   }
 }
