Bug 1118486 - Part 1: Use `= delete` instead of MOZ_DELETE directly; r=Waldo Most of this patch (with the exception of dom/bindings/Codegen.py) was generated by the following bash script: #!/bin/bash function convert() { echo "Converting $1 to $2..." find . ! -wholename "*nsprpub*" \ ! -wholename "*security/nss*" \ ! -wholename "*/.hg*" \ ! -wholename "*/.git*" \ ! -wholename "obj-*" \ -type f \ \( -iname "*.cpp" \ -o -iname "*.h" \ -o -iname "*.cc" \ -o -iname "*.idl" \ -o -iname "*.ipdl" \ -o -iname "*.ipdlh" \ -o -iname "*.mm" \) | \ xargs -n 1 sed -i -e "s/\b$1\b/$2/g" } convert MOZ_DELETE '= delete'
