Llodra has already qualified with Clément in doubles, he will be there. But only in doubles so far.
If Gilles still is 4th Frenchie in 3 weeks, he will play in singles at the Olympics.
Or at least that's what I've understood.
I think each country is allowed to send 4 singles players and 2 doubles players (and they can have 2 doubles teams, so 2 of the singles players will also play in doubles).
If Llodra also qualifies in singles, one more doubles player spot will be available, for example for Santoro (who wanted to play with Gasquet in Beijing).
But if Gilles defends his spot for the remaining 3 weeks, they're forced to send Gasquet-PHM-Tsonga-Simon in singles and Llodra-Clément in doubles (with probably Gasquet-Tsonga playing doubles too).
But maybe we should ask Renaud, he's good for all this stuff...
