Hello Everyone,
I am currently trying to take certain functions (marked by certain
attributes) and create vector version along with the scalar versions of the
function. For example, let's say I have a function my_add that is marked with a
certain attribute, I am trying to clone it into my_add_vector and still keep
the original my_add. For this, I am trying to use tree_function_versioning in
cgraphunit.c to clone the cgraph_node into a new function. Does this function
actually create a 2nd function (called my_add_vector) and copy the body from
my_add function to the my_add_vector function or does it just create a node
called my_add_vector and then create a pointer to the body of the my_add?
Is there a better approach for doing this?
Any help is greatly appreciated!
Thanks,
Balaji V. Iyer.
