No, the const attribute does not cause to produce wrong code.
On powerpc-darwin with your testcase, I get:
        mflr r0
        lis r3,ha16(LC0)
        la r3,lo16(LC0)(r3)
        stw r0,8(r1)
        stwu r1,-64(r1)
        bl _nanf
        li r3,0
        fcmpu cr7,f1,f1
        bne- cr7,L5


You can see the floating point compare happens but only one call to nanf.
