RE: Function Name from CALL_INSN RTX

["Iyer, Balaji V" <balaji dot v dot iyer at intel dot com>]

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 there a function for this purpose? 

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.
