No, it doesn't. Assembler complains on:
pushq $0xbf800000
Which makes this a binutils bug. Let's ask H.J.

------- Comment #5 from hjl dot tools at gmail dot com 2010-08-06 21:51 -------
The bug is in gcc. "pushq $imm32S" only takes 32bit signed extended
immediate. You can't push 0xbf800000. Instead, you push -1082130432
or 0xffffffffbf800000.
