MIPS ABI- Dead end functions

[Shane Nay]

In the case that a function is dead end, i.e. has no references to 
the gp, like calling another function, then the sequence-
lui gp, 0xfc0 /* some number */
addiu gp, gp, offestval
addu gp, gp, fncaddr

I think is not required.  Like for instance-
int mult(int x, int y) {
        return x*y;
}

creates-
00000000 <mult>:
   0:   3c1c0000        lui     gp,0x0
   4:   279c0000        addiu   gp,gp,0
   8:   0399e021        addu    gp,gp,t9
   c:   03e00008        jr      ra
  10:   00851018        mult    v0,a0,a1

when it could just be-
   0:   03e00008        jr      ra
   4:   00851018        mult    v0,a0,a1

right?, or am I missing something?  Normally gcc would pull out 
unused register references in it's optimization passes (REG_DEAD), 
but this stuff is being generated from macros in the assembler-

        .frame  $sp,0,$31               # vars= 0, regs= 0/0, args= 
0, extra= 0
        .mask   0x00000000,0
        .fmask  0x00000000,0
        .set    noreorder
        .cpload $25
        .set    reorder
        .set    noreorder
        .set    nomacro

So..., how can this situation be handled cleanly?  The cleanest way I 
can think of is to modify gcc so that it does not generate the 
.cpload $25 sequence in the case that $gp is unused.  What do you 
think?

Thanks,
