|
|
#
|
|
# This script creates additional helper .app bundles for Chromium, based on
|
|
# the existing helper .app bundle, changing their Mach-O header's flags to
|
|
# enable and disable various features. Based on Chromium Helper.app, it will
|
|
# create Chromium Helper EH.app, which has the MH_NO_HEAP_EXECUTION bit
|
|
# cleared to support Chromium child processes that require an executable heap,
|
|
# and Chromium Helper NP.app, which has the MH_PIE bit cleared to support
|
|
# Chromium child processes that cannot tolerate ASLR.
|
|
#
|
|
# This script expects to be called from the chrome_exe target as a postbuild,
|
|
# and operates directly within the built-up browser app's versioned directory.
|
|
#
|
|
# Each helper is adjusted by giving it the proper bundle name, renaming the
|
|
# executable, adjusting several Info.plist keys, and changing the executable's
|
|
# Mach-O flags.
