Hi All,
Is it possible to write a opt pass , which can run on one particular function( input from command line) in a module ?

Thanks,
Abhishek

You can add a global variable to your module that consists
of an array of strings. Each string is the name of a function
your pass should optimize.

Should be simple: add a command-line option for the pass name, and have the pass ignore any functions that don't have that name...

You can also use the llvm-extract tool to split the one function you're interested out into its own module.
