Summary0000257: WIldcarded super calls with arguments
DescriptionShort: Allow wildcarded calls with arguments
From: Lars
Date: 2001-08-02
Type: Feature
State: New

Allow wildcarded calls with arguments, e.g. "*":foo(i).

For this, implement a new opcode ROLLOVER, which takes this stack

   mixed* results = ({ r1, r2, r3 })
   arg1
   arg2
   arg3
   arg4
   r4 <--- sp

and leaves it behind as

   mixed* results = ({ r1, r2, r3, r4 })
   arg1
   arg2
   arg3
   arg4
   arg1
   arg2
   arg3
   arg4 <--- sp

so the sequence could be

   compute arg1
   compute arg2
   compute arg3
   compute arg4
   const0
   rollover
   call fun
   rollover
   call fun
   roll over
   call fun
   ...

With modifications of course.
TagsNo tags attached.

Just wanted to bring this issue back to the top, since I intended to post the identical feature request against 3.5.x.

I transferred the issue to 3.5. Once we have dealt with it, we should decide if we backport it.

 I plan to implement this in the following way:

New opcodes:
  ARRAY <n>, it's the same as aggregate(<n>), but <n> is put into the program, not on the stack.
  DUP_N <offset> <num>, copies values stack[1-offset-num] ... stack[-offset] on top of the stack.
  PUT_RESULT <offset> <num>, removes the top value off the stack und puts it into the array stack[-offset-1] at position <num>

For three inherited functions and two arguments there would be the following program and the corresponding stack.

ARRAY 3
    ({0,0,0})

SAVE_ARG_FRAME
    ({0,0,0})
    ArgFrame

Compute arguments
    ({0,0,0})
    ArgFrame
    Arg1
    Arg2

SAVE_ARG_FRAME
    ({0,0,0})
    ArgFrame
    Arg1
    Arg2
    ArgFrame

DUP_N 1 2
    ({0,0,0})
    ArgFrame
    Arg1
    Arg2
    ArgFrame
    Arg1
    Arg2

CALL_INHERITED
    ({0,0,0})
    ArgFrame
    Arg1
    Arg2
    ArgFrame
    Result1

PUT_RESULT 4 0
    ({Result1, 0, 0})
    ArgFrame
    Arg1
    Arg2
    ArgFrame

DUP_N 1 2
    ({Result1, 0, 0})
    ArgFrame
    Arg1
    Arg2
    ArgFrame
    Arg1
    Arg2

CALL_INHERITED
    ({Result1, 0, 0})
    ArgFrame
    Arg1
    Arg2
    ArgFrame
    Result1

RESTORE_ARG_FRAME
    ({Result1, 0, 0})
    ArgFrame
    Arg1
    Arg2
    Result1

PUT_RESULT 3 1
    ({Result1, Result2, 0})
    ArgFrame
    Arg1
    Arg2

CALL_INHERITED
    ({Result1, Result2, 0})
    ArgFrame
    Result3

RESTORE_ARG_FRAME
    ({Result1, Result2, 0})
    Result3

PUT_RESULT 0 2
    ({Result1, Result2, Result3})
