-# This script makes sure that no __OBJC,__image_info section appears in the

-# section appears, the script prints an error message and exits nonzero.
-#
-# Why is this important?
-#
-# On 10.5, there's a bug in CFBundlePreflightExecutable that causes it to
-# crash when operating in an executable that has not loaded at its default
-# address (that is, when it's a position-independent executable with the
-# MH_PIE bit set in its mach_header) and the executable has an
-# __OBJC,__image_info section. See http://crbug.com/88697.
-#
-# Chrome's main executables don't use any Objective-C at all, and don't need
-# to carry this section around. Not linking them as Objective-C when they
-# don't need it anyway saves about 4kB in the linked executable, although most
-# of that 4kB is just filled with zeroes.
-#
-# This script makes sure that nobody goofs and accidentally introduces these
-# sections into the main executables.
