I am folding the function call __function_size(foobar) to a new symbol foobar@size. The reference to function foobar disappears. Can I keep a reference foobar attached to the symbol somehow? > Or, you could write a tiny pass which set DECL_PRESERVED_P for each > function passed to __function_size. > Might do as a last resort. > Or, perhaps you could handle it in expand_builtin rather than > fold_builtin. > I thought that the only way to replace a builtin expression was to use fold_builtin and expand_builtin had other purposes. How can I use the expand_builtin to do replacement? Cheers, Paulo Matos -- PMatos
