So! "Sizer", windows executable size reporting tool. It was time to resurrect it, make it stop using msdia_*.dll and instead use @molecularmusing raw_pdb.

Much faster, hopefully better as well.

Testing would be appreciated! https://github.com/aras-p/sizer/releases/tag/v0.5.0

Release v0.5.0: large speedup, no more DIA SDK · aras-p/sizer

Large speedup and removed dependency on msdia*.dll, by switching to MolecularMatters/raw_pdb library for PDB file parsing. Sizer no longer uses MS DIA SDK, so maybe someday it will be able to run o...

@molecularmusing ...aaand now Sizer itself can run on Mac or Linux too. It still only analyzes windows executables/PDBs of course. https://github.com/aras-p/sizer/releases/tag/v0.5.1

Release v0.5.1: multi-platform and cmake · aras-p/sizer

Sizer now builds on Windows, Mac and Linux. Note that it still only analyzes the Windows executables/PDBs, but can do that while running on Mac/Linux. The build system was changed to CMake. Github ...

@aras @molecularmusing you're a hero of the people!!!

@aras @molecularmusing Just as I archived https://github.com/zeux/codesize a month or so ago :D

@zeux "archived by the owner on Jan 4, 2023" I think you lost 6 months of time awareness!

Arseny Kapoulkine Aug 5, 2023

@aras Oops :) I guess I gradually archived a bunch of older projects and forgot when I started!

@aras @molecularmusing Just when I was thinking its probably time we start caring more about Godot binary sizes (we never kind of did because its still small when compressed). Great timing and thanks for the tool!

@reduz @aras @molecularmusing There's also Microsoft's own SizeBench tool to consider these days, which provides a lot of useful information, like how much is duplicated/wasted between multiple instances of the same template function, or if some static data is present in multiple compilation units. It also gives you the ability to diff two PE files to see what exactly caused an increase in size: https://devblogs.microsoft.com/performance-diagnostics/sizebench-a-new-tool-for-analyzing-windows-binary-size/

@mihe @reduz @molecularmusing I tried SizeBench just two days ago. First impression: 100+ MB app size is funny for a size optimization tool :) Then, it refused to work on any PDBs I had, mostly saying "yo, incremental linking, I can't do that"

Aras Pranckevičius Aug 5, 2023

@mihe @reduz @molecularmusing ...but cmake default RelWithDebInfo, i.e. the only sane config that produces PDBs for optimization, does also enable incremental linking by default! This makes SizeBench not work on like 99% of cmake based projects, without custom build hacks :(

Mikael Hermansson Aug 5, 2023

@aras @reduz @molecularmusing Right, yeah, that's a bummer. I was curious why I hadn't run into that limitation, and it seems to be because I enable LTCG through CMake's INTERPROCEDURAL_OPTIMIZATION property, which rightfully disables incremental linking. LTCG tends to be a non-starter for larger projects though, from what I've seen, and at that point you might as well just append /INCREMENTAL:NO yourself I guess.

@aras Thank you. After your post, tried to get the same info for @defold (it builds with Clang) and analize it on Mac. It's not so hard to do by adding
'-Wl,-map, output.map' as linker flag and using https://apps.apple.com/app/fastlinkmapanalyzer/id1595283055 as viewer.

I can't say it was super useful in my case, because it's hard to squeeze out kilobytes from already small code.
But it's good to know that it's possible to get and analyze this info easily.

@aras Great move! :)

Stefan Reinalter Aug 5, 2023

@aras Great stuff Aras!
Please feel free to open a PR if you feel useful stuff is missing in raw_pdb. It's certainly not a complete msdia replacement yet.

Aras Pranckevičius Aug 5, 2023

@molecularmusing I did open one tiny one-liner PR. Everything else worked like a charm (besides PDB itself being kinda strange, but that’s life)

Aras Pranckevičius Aug 5, 2023

@molecularmusing ohh lol, I failed at GitHub and opened PR to the wrong repo :/ https://github.com/aras-p/raw_pdb/pull/1

Add DBIStream::GetHeader() by aras-p · Pull Request #1 · aras-p/raw_pdb

This can be useful for tools to check whether the PDB is stripped (header.flags & 2) or whether it was produced with incremental linking (header.flags & 1).
