pro_and_epilogue pass ran several time for same function?

[Paulo J. Matos]

Hi all,

I just noticed that the pro_and_epilogue pass in gcc3.4.3 for certain
functions is ran multiple times with sibcalls enabled. Why is that?

What I did was to put a printf on the epilogue and sibcall_epilogue
pattern so that during compilation it prints the name of the function
currently generating the epilogue for, however, I get a print in
epilogue and a print in sibcall_epilogue for the same function a
couple of times. Why?

Cheers,
