Thanks for the help Ian. The function get_callee_fndecl takes in a tree and=
 returns a tree. I would like to get the function name from the RTX. Is the=
re a function for this purpose?=20

Thanks,

Balaji V. Iyer.

Not always, of course.  A call through a function pointer has no name.

The function get_callee_fndecl will do its best to get the function decl
from a CALL_EXPR.
