cargo-llvm-lines

Count the number of lines of LLVM IR across all instantiations of a generic function.

Installation

Install with cargo install cargo-llvm-lines.

Output

One line per function with three columns of output:

1. Total number of lines of LLVM IR generated across all instantiations of the function.
2. Number of instantiations of the function. For a generic function, roughly the number of distinct combinations of generic type parameters it is called with.
3. Name of the function.
