Share optimized code for closures. · bb0a2ea7

fschneider@chromium.org authored Jun 14, 2012

Each SharedFunctionInfo gets an optimized code map to store
one optimized code object per context. When allocating a new
closure we consult this map and check if there is optimized code
that can be shared.

This patch is based on an original patch
