assembler code of nanf-test.c
Following a piece of the objdump of the nanf-test:
:
:
int
main (void)
{
0: e6 2f mov.l r14,@-r15
2: 22 4f sts.l pr,@-r15
4: f8 7f add #-8,r15
6: f3 6e mov r15,r14
int op;
op = (nanf ("") != nanf ("") );
8: e3 62 mov r14,r2
a: c8 72 add #-56,r2
c: 00 e1 mov #0,r1
e: 1f 12 mov.l r1,@(60,r2)
if (!op) {
10: e3 61 mov r14,r1
12: c8 71 add #-56,r1
14: 1f 51 mov.l @(60,r1),r1
16: 18 21 tst r1,r1
18: 08 8b bf 2c <main+0x2c>
printf ("Test NAN Failed!\n");
1a: 09 d1 mov.l 40 <main+0x40>,r1 ! 0x0 <main>
1c: 13 64 mov r1,r4
1e: 09 d1 mov.l 44 <main+0x44>,r1 ! 0x0 <main>
20: 0b 41 jsr @r1
22: 09 00 nop
return (1);
24: 01 e1 mov #1,r1
26: 12 2e mov.l r1,@r14
28: 02 a0 bra 30 <main+0x30>
2a: 09 00 nop
}

Note that I using sh4 architecture.
In attach you can find the nanf-test.s that doesn't contains any reference
to nanf symbol.
