No. Once a function is inlined, the register allocator does not really know that the inlined body comes from a different function. For all it knows, the code comes from the same parent function. It's the same effect as if you had inlined the function in a text editor and compiled the result (well, except that the inliner keeps enough debugging information around to inform the debugger about it).
