| michael@0 | 8 | # |
| michael@0 | 9 | # This script creates additional helper .app bundles for Chromium, based on |
| michael@0 | 10 | # the existing helper .app bundle, changing their Mach-O header's flags to |
| michael@0 | 11 | # enable and disable various features. Based on Chromium Helper.app, it will |
| michael@0 | 12 | # create Chromium Helper EH.app, which has the MH_NO_HEAP_EXECUTION bit |
| michael@0 | 13 | # cleared to support Chromium child processes that require an executable heap, |
| michael@0 | 14 | # and Chromium Helper NP.app, which has the MH_PIE bit cleared to support |
| michael@0 | 15 | # Chromium child processes that cannot tolerate ASLR. |
| michael@0 | 16 | # |
| michael@0 | 17 | # This script expects to be called from the chrome_exe target as a postbuild, |
| michael@0 | 18 | # and operates directly within the built-up browser app's versioned directory. |
| michael@0 | 19 | # |
| michael@0 | 20 | # Each helper is adjusted by giving it the proper bundle name, renaming the |
| michael@0 | 21 | # executable, adjusting several Info.plist keys, and changing the executable's |
| michael@0 | 22 | # Mach-O flags. |
