How Static Initializers are Checked

• For Linux and Mac:
  • The expected count is stored in //infra/scripts/legacy/scripts/slave/chromium/sizes.py
• For Android:
  • The expected count is stored in the build target //chrome/android:monochrome_static_initializers

Removing Static Initializers

Common fixes include:

• Add constexpr,
• Use LazyInstance<>,
• Move global variable to be a static variable within a function that returns it.

Listing Static Initializers

For Linux:

tools/linux/dump-static-initializers.py out/Release/chrome

For Android:

build/android/resource_sizes.py --chromium-output-directory out/Release --dump-static-initializers out/Release/apks/MonochromePublic.apk
tools/binary_size/diagnose_bloat.py HEAD
