The only binary that supports ICU data tables is d8. The location of the data table file has to be passed via a command line switch: $ out/x64.optdebug/d8 --icu-data-file=out/x64.optdebug/icudtl.dat BUG=72633,v8:3142 R=danno@chromium.org LOG=y Review URL: https://codereview.chromium.org/209323014 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@20239 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
