Fix for performance issue 353661 - 23% regression in dromaeo. · c92de5d1

mvstanton@chromium.org authored Mar 20, 2014

The issue was that a previous fix to avoid a logic error was not
targeted enough: it allowed non-transitioning stores to fall
into a code path meant to preserve monomorphic state in the
case of a transitioning store.

Increase the "local variables in a function" limit. · e9358fa9

marja@chromium.org authored Mar 20, 2014

The limit was originally added to avoid having large user-controlled constants
(variable indexes) in the code generated by full-codegen.

History behind this change:

The original CL for adding the limit was https://codereview.chromium.org/7003030
and at that time, the limit was 32767.

Reason for adding the limit (in CL comments): "The motivation behind this change
is to avoid large user controlled constants in the code. The slot_operand used
in the IA32 full code generator uses a relative load where the local index is an
(negative) immediate."

The limit was then bumped to 65535 by https://codereview.chromium.org/10965063
and to 131071 by https://codereview.chromium.org/11099063.

Make PreParser track valid left hand sides. · d017e6ce

marja@chromium.org authored Mar 20, 2014

Notes:
- This makes PreParser produce invalid_lhs_in_assignment and
invalid_lhs_in_prefix_op. Other errors will follow as the corresponding funcs
move to ParserBase.
- PreParserExpression::IsStrictFunction and StrictFunction() are not needed any
more -> removed them.

MIPS: Pretenure call new support. · a03e80c3

plind44@gmail.com authored Mar 19, 2014

Port r20076 (b7b1372)

Original commit message:
When FLAG_pretenure_call_new is on, we emit mementos on new object creation
in full code, and consume the feedback in crankshaft. A key difference in the
generated code for stubs is the allocation of an additional type vector slot for the
CallNew AST node, which simplifies the CallConstructStub and CallFunctionStub
considerably.

Some performance tuning still needs to be addressed, therefore the flag is off at
this moment, though fully functional. The goal is to remove the flag as soon as
possible, which allows much code deletion (yay).
