Generators save and restore stack handlers · 75d939ac

wingo@igalia.com authored May 08, 2013

This CL adds machinery to unwind stack handlers from the stack and store
them into a generator's operand array.  It also includes routines to
reinstate them.  Together this allows generators to yield within
try/catch and try/finally blocks.

Do not change environment between simulate and scope with no observable... · e5a29e8f

ulan@chromium.org authored May 08, 2013

Do not change environment between simulate and scope with no observable side-effects in HandlePropertyAssignment.

LChunkBuilder reconstructs the environment by applying simulates. A scope with no observable side-effects has no simulates. If the scope deoptimizes, then LChunkBuilder would miss the changes to the environment between the last simulate and the scope.
