Goal is to make assemblies for browser smaller by automatically trimming code that was kept alive by the unsupported methods.

  • when method is marked with body="pnse" in ILLink.Substitutions.xml
  • or when ILLink command line argument is passed --target-os browser and the method is marked with [UnsupportedOSPlatform ("browser")] attribute
  • enable for browser
