cfun and current_function_decl

[Paulo J. Matos]

Hi,

As a continuation of my previous issue, what's the difference between
cfun and current_function_decl and which one should I use to walk the
tree during TARGET_FUNCTION_OK_FOR_SIBCALL?

[In the internals document I only found references to cfun and even
there was hard to understand what it actually is]

Cheers,
