QUESTION
I am profiling my program;s compilation and looking for bottlenecks. I originally thought template instantiation would be the most expensive part but seems to be callgraph funciton expansion. Problem is, I have no idea what that stage refers to.
...ANSWER
Answered 2021-Dec-20 at 21:02It appears to be part of the optimization process implemented by GCC. I was able to find one reference, The GCC call graph module, which describes it as the final step performed by the front-end of the compiler:
- Expansion: We proceed in reverse DFS order on functions that are still present in the call-graph, applying inter-procedural optimizations such as inlining to the functions, and finally leaving them to the back-end to do the actual optimization and compilation.

Answered 2021-May-07 at 17:49So I did find a package that seems to handle printing a tree from a graph on the
command line [1]. However I thought about it some more, and a printed tree
might not be the best solution to my issue. What I want to do, is return an
error from one of my functions. However to do that, I need to propagate the
error all the way up to main
. As this can be several layers, I thought it
would be best if I start from main
, and work my way down to the desired
function. That way, I can the work in stages if need be. The issue is, how do I
get an ordered list of these functions? I found a solution with tsort

Why is TypeScript not having an issue with this code but the linter does? Do both not need to be alligned?
In Typescript, something with type any
can be assigned to anything. Using any
essentially removes typesafety from that part of the code. For example:

QUESTION
I currently working on an automatic code documentation tool. For it, I am using Soot for constructing the call graph. However, Soot seems to be including the standard java libraries in this call graph. This is of course, not desirable since I am only interested in the actual classes of the program that I will be generating documentation for.
This is program I used to test the callgraph:
...ANSWER
Answered 2020-Jan-28 at 15:25Ok, I found a solution.
We just suppress the visit
calls from classes from the java package.
so by using child.isJavaLibraryMethod()
to check if it is from the java package.
If it is from the java package we simply do not call visit
with that class, so by adding this check for the parent and child calls and suppressing the output, we get the correct callgraph. (and as a bonus it is much faster as you're not traversing the java library anymore.
so the code is changed to:

Install callgraph
You can use callgraph like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
