9 years agoUnify decoding of deoptimization translations.
jarin [Mon, 8 Jun 2015 10:04:51 +0000 (03:04 -0700)]
Unify decoding of deoptimization translations.

This unifies methods Deoptimizer::DoTranslateCommand, Deotpimizer::DoTranslateObject and the arguments object materializer.

To unify these, we have to separate reading of the input frame from writing to the output frame because the argument materializer does not write to output frames.

Instead, we now deoptimize in following stages:

1. Read out the input frame/registers, decode them using the translations from the deoptimizer and store them in the deoptimizer (Deoptimizer::translated_state_). This is done in TranslatedState::Init.

2. Write out into the output frame buffer all the values that do not require allocation. We also remember references to the values that require materialization. As before, this is done in Deoptimizer::DoCompute*Frame method, but instead calling to DoTranslateCommand, we use the translated frame to obtain the values and write them to the output frames.

3. The platform specific code then sets up the output frames and calls into the deoptimization notification. This has not been changed at all.

4. Once the stack is setup, we handlify all the references in the saved translated values (TranslatedState::Prepare).

5. Finally, we materialize all the values we remembered in step (1) and write them to their frames on the stack (using the TranslatedValue::GetValue method).

Fix arrow functions requiring context without slots.

This fixes a corner-case where arrow functions that require a context
allocate none, because there are no additional slots allocated. Note
that this didn't happen with true function scopes because they always
had at least the receiver slot.

The outcome was a context chain that no longer was in sync with the
scope chain, hence context slot loads were bogus. This is observable
using the DYNAMIC_LOCAL optimization in all compilers.

port e2e47f30be06e6ea6b8a3cc90138381914ecd07d (r28711)

original commit message:

    [turbofan] First step towards sanitizing for-in and making it optimizable.

    In a nutshell: The FILTER_KEY builtin is gone, and was replaced by a
    simple runtime call to ForInFilter, which does everything and is even
    cheaper (because FILTER_KEY used to call into the runtime anyway).
    And ForInFilter returns either the name or undefined, which makes it
    possible to remove the control flow construction from the AstGraphBuilder,
    and thereby make both the initialization and the per-loop code of for-in
    optimizable later (in typed lowering).
