seeprofiler's Introduction

See++ Compiler Profiler

Visual C/C++ Profiler for Clang 9 or higher. Using the flag -ftime-trace (see Clang 9 release notes) Clang will create a time report (.json) next to the generated .obj file. Within See++ Compiler Profiler multiple reports can be aggregated in one single view, giving valuable information at a project scale.

It will help identify and track how includes, templates, function instantiations, etc. perform inside the compiler, being able to pinpoint the most expensive ones (or anything of particular interest, really).

Usage

Drag or open the folders and files to be inspected. All the files will be parsed (this can take some time if the project is really big) and the overview window will show up with a full recap for all translation units found.

The graphs on top can be used to switch between the different categories in order to visualize more specific data.

Any row can be double-clicked to visualize the actual timeline for the given translation unit or for the translation unit that contains the worst offender (for source, class, function...).

(use Ctrl+MouseWheel for zoom in/out)

How to build the project

First of all node.js needs to be installed.

Make sure the commands are run inside the SeeProfiler subfolder:

cd SeeProfiler

Install the project dependencies:

npm install

Run the application:

npm start

Alternatively the App can be launched within Visual Studio Code.

Creating a package

To export the project as a standalone application:

npm run export

External Libraries

See++ Compiler Profiler is based on Electron.

seeprofiler's Issues

The font size is unreadable on M1

I was excited about this over Compiler Score since it works on macOS. So Xcode is generating the json, and SeeProfile opens it. But all text is displayed without regard to retina resolution. The font looks like it's 8pt font, but on a 14" MBP M1 that's super tiny. And cmd +/- don't magnify the render. Similarly impossible to read the flamechart when clicking on a file.

Pinch-zoom seems to work from touchpad, but panning doesn't. I've gotten used to Perfetto's wasd for scroll left-right and zoom in-out. Also a hover tip with name and time would save having to zoom in/out when the timing chunk is too small or not enough space to display the name.

Workaround for now I guess would be to reduce monitor resolution or display on a non-retina display. This is a cool profiler, and I've also been trying to integrate fastl into my kram project. I used to work on the precursor to EASTL, but that stl is huge. Keep up all the good work!

No window opens on MacOS

I tried to run the application on MacOS, but no window opens.

The following error is logged when running the application via the command line:

Error: Image could not be created from /Users/username/Downloads/SeeProfiler-darwin-x64/SeeProfiler.app/Contents/Resources/app/main/data/logo.ico
    at App.CreateWindow (/Users/username/Downloads/SeeProfiler-darwin-x64/SeeProfiler.app/Contents/Resources/app/app.js:39:9)

Timings need tracked a a self time

Seems like the timings are not tracked as a self time. This is problematic for assessing which header to target. When X includes Y, they're not both 1s of Source time in the spreadsheet. X is 0.1s, and Y is 0.9s.

Show full file name as tooltip in flame graph

If there is insufficient space in the flame graph, then file names will get truncated.

I know, that I can zoom in and zoom out, but I think, it would be useful, to get a tooltip with the complete file name when hovering with the cursor over a certain item.

Crash at startup

I get the following errors on Debian GNU/Linux bookworm/sid x86_64, with npm 8.12.1 and nodejs
v16.14.2:

Uncaught ReferenceError: require is not defined
