Directly generate a Mach-O dynamic library using gen_snapshot. [reland] by sstrickl · Pull Request #174870 · flutter/flutter

sstrickl · 2025-09-03T11:56:34Z

Instead of generating assembly code that is then compiled to a Mach-O dynamic library, use the new app-aot-macho-dylib output option for gen_snapshot to generate the Mach-O dynamic library without the assembly step.

This is a reland of #171626, with the necessary changes to avoid the issue found in #174393 where DWARF information was being retained in the final snapshot. The initial PR state are the original commits landed in the previous PR, with a followup commit containing the fix for that issue: the DWARF information is moved into an associated relocatable object, so the information is still accessible by dsymutil before the snapshot is stripped.

As mentioned in the PR description, the only commit that differs from the original PR that @bkonyi reviewed is the last one that adds the --macho-object= command line argument to specify where the relocatable object goes. All the other work is Dart-side.

LGTM, thanks for re-landing with the fix.

Directly generate a Mach-O dynamic library using gen_snapshot.

cc04070

Instead of generating assembly code that is then compiled to a Mach-O dynamic library, use the new app-aot-macho-dylib output option for gen_snapshot to generate the Mach-O dynamic library without the assembly step.

Use new --macho-min-os-version flag to pass this to gen_snapshot.
