An important interprocedural data flow analysis problem is the deter- mination of which parameters to a given procedure will be constant at run time.

For function calls that the compiler believes are frequently executed the compiler may decide to replace the instructions of the call with code for the function itself. Intermediate Code Generation Test. Other optimizations look at only a single function or even a single block of.
