Hi!

We're trying to improve the optimization process in GCC by adding manual
optimization attributes to some needed functions. I couldn't yet find the
code routine where the attributes can be added to a special function
declaration. Could you please help me understand what's happening there?

Thanks in advance.

I think you need to elaborate on what kind of attributes and what exactly a
special function declaration is for us to give a reasonable answer.  Maybe
giving an example helps understanding your request.

Hi! I'm trying to modify the GCC source code to get something done. But
there's a difficulty in understanding how to use some functions and data
structures. Please help me with some hints.

Here is the problem: in the file GCC-source/gcc/c/c-decl.c, before
'c_decl_attributes' is called in 'start_function', I want to insert some
additional optimize attributes in 'attributes' tree to be proceed, but I
could not find the correct way to insert a new tree in it.
 Thanks in advance.
