Refactor impellerc_main to better organize some of its logic by b-luk · Pull Request #182783 · flutter/flutter

b-luk · 2026-02-23T20:07:00Z

No-op change to better organize some of the logic in impellerc_main. This makes some of the followup work for #182400 easier to do.

Instead of creating each compiler inside the OutputIPLR function, create them outside of OutputIPLR and pass the list of compilers into OutputIPLR. This way, the created compilers can be re-used for the alternate OutputSLFile step and for the subsequent OutputSPIRV, OutputReflectionData, and OutputDepfile steps.
Moves the logic to output the SPIRV file into a OutputSPIRV helper function instead of having it inlined in Main.
Move/fix some of the existing comments about the 4 steps performed in Main.

Code Review

This pull request refactors impellerc_main.cc to improve the organization of its logic. Compilers are now created once and reused across different output steps. Logic for outputting SPIR-V has been extracted into a helper function, and comments in the Main function have been updated to reflect the new structure. My review identifies a missing error check in the refactored OutputIPLR function that was present in the original code.

please remove type deduction, it's important here since you may be accidentally introducing a copy.

https://google.github.io/styleguide/cppguide.html#Type_deduction

I changed it to be std::shared_ptr<RuntimeStageData::Shader>. But can you clarify what you mean when you say auto can accidentally introduce a copy?

My understanding is that auto would be std::shared_ptr<RuntimeStageData::Shader> here, right? So I think it creates a copy of the shared_ptr. But that is fine because the ptr is lightweight to copy, and the underlying RuntimeStageData::Shader is not copied. Is that correct? Replacing the auto with std::shared_ptr<RuntimeStageData::Shader> doesn't change anything, does it? Or am I misunderstanding, and I should I be doing something else?

std::shared_ptr in aggregate it can cause performance problems in systems programming. It introduces atomics for synchronizing ref counts. This is why languages like Rust opted to have 2 types of ref counting (see Arc vs Rc).

In this case the getter is returning a std::shared_ptr by value, so the deduced type is not hiding an extra copy. We've had instances where auto has hid them before so it's best to stick to the C++ style guide, especially when capturing intermediate values.

-static bool OutputIPLR(
-    const Switches& switches,
-    const std::shared_ptr<fml::Mapping>& source_file_mapping) {
+static std::shared_ptr<Compiler> CreateCompiler(


nit: i know it's done elsewhere in this file but static functions is kind of a c way or doing things, not a c++. it should be anonymous namespaces.

Done. Moved all the static functions into an anonymous namespace.

-  if (switches.iplr && !OutputIPLR(switches, source_file_mapping)) {
-    return false;
+  std::vector<std::shared_ptr<Compiler>> compilers;


nit: put a .reserve() call in here since we know the size.

gaaclarke · 2026-02-23T21:56:48Z

-    return false;
+  std::vector<std::shared_ptr<Compiler>> compilers;
+  for (const auto& platform : switches.PlatformsToCompile()) {
+    auto compiler = CreateCompiler(platform, source_file_mapping, switches);


remove auto
