hi, I wonder if it's possible to ask gcc to generate code for a function as if all registers were callee-saved. i.e., I would like to make sure that my function does not touch _any_ register from the perspective of the caller, independently from the abi calling convention. I could write my own prologue/epilogue to save/restore all registers by hand but it's not really a lot of fun... Mathieu -- Mathieu Lacage <mathieu.lacage@xxxxxxxxx>
