This might be a cost issue in the ppc backend (and so target, not
rtl-optimization).

GCSE is pulling out the invariant.
Before GCSE we had:
(insn 20 5 6 3 t.c:6 (set (reg/f:SI 121)
(plus:SI (reg/f:SI 113 sfp)
(const_int 8 [0x8]))) -1 (nil))
(insn 6 20 7 3 t.c:6 (set (reg:SI 3 3)
(reg/f:SI 121)) 325 {*movsi_internal1} (expr_list:REG_EQUAL (plus:SI
(reg/f:SI 113 sfp)
(const_int 8 [0x8]))
(nil)))
(call_insn 7 6 8 3 t.c:6 (parallel [
(set (reg:SI 3 3)
(call (mem:SI (symbol_ref:SI ("f0") [flags 0x41] <function_decl
0xf7d41e00 f0>) [0 S4 A8])
(const_int 0 [0x0])))
(use (const_int 0 [0x0]))
(clobber (reg:SI 65 lr))
]) 450 {*call_value_nonlocal_sysvsi} (nil)
(expr_list:REG_DEP_TRUE (use (reg:SI 3 3))
(nil)))
(insn 8 7 10 3 t.c:6 (set (reg:SI 119 [ D.1255 ])
(reg:SI 3 3)) 325 {*movsi_internal1} (nil))
(insn 10 8 11 3 t.c:6 (set (reg:CC 120)
(compare:CC (reg:SI 119 [ D.1255 ])
(const_int 0 [0x0]))) 471 {*cmpsi_internal1} (nil))
(jump_insn 11 10 19 3 t.c:6 (set (pc)
(if_then_else (ne (reg:CC 120)
(const_int 0 [0x0]))
(label_ref 9)
(pc))) 560 {*rs6000.md:13857} (expr_list:REG_BR_PROB (const_int
8600 [0x2198])
(nil)))
And then it pulled out the set outside of the loop.
Why didn't we combine the set of reg 121 into its one use in the set of 3
before the fact (like in fwprop)?

After changing fwprop.c to do the prop if it was used only once,
loop-invariant.c pulls it out again.

Now in gain_for_invariant, size_cost is zero, even though we have a hard
register so we know it will have an extra move.

Here is another testcase which shows the issue:
int f(int b);
float g(int a)
{
while (f(a + 1));
while (f(a));
}
--- CUT ---
This increases the need for another volatile register and in fact increases
register pressure even more.

------- Comment #12 from pinskia at gcc dot gnu dot org 2008-09-25 02:52 -------
This happens also for x86_64.
on the trunk:
L2:
movq %rbx, %rdi
call _f0
testl %eax, %eax
jne L2
4.0.1:
L3:
leaq -4(%rbp), %rdi
call _f0
testl %eax, %eax
jne L3
--- CUT ---
With the fwrprop patch which I am working on and disabling move loop
invariants, we get back:
L2:
leaq -4(%rbp), %rdi
call _f0
testl %eax, %eax
jne L2
-- CUT ---
move-loop-invariants still moves this out of the loop though.
So to answer Richard's question about this being a target issue, since it is
also happens on x86_64 and move loop invariants does not take into account the
cost of the move instruction, I am going to say this is a move loop invariant
issue (after I fix the fwprop one).

------- Comment #17 from bonzini at gnu dot org 2009-02-06 09:53 -------
without a testcase where this affects performance, it should not be P2 (though
it should be fixed).

------- Comment #19 from pinskia at gcc dot gnu dot org 2010-03-02 18:24 -------
Here is a testcase which shows the problem on MIPS too:
extern int f0(int *, int *);
int
f1()
{
int x = 0 , x1 = 0;
while (f0(&x, &x1));
return x + x1;
}
