inlined functions and ABI guarantees

[Maurizio Vitale <maurizio.vitale@xxxxxxxxxxxxxxxxxxxxxx>]

Is it safe to assume that GCC saves "callee-owned" registers around a  
function call that gets inlined?
Or does GCC look inside the expansion and determines what needs to be  
saved?

I'm asking because I have functions that do the equivalent of a  
context-switch and I suspect I have to add
a clobber that explains to GCC that all the callee-owned registers  
are really fubar even when that's not ppent from the function expansion.

Best regards,
