ffb70bc843 Improved phi reachability computation a bit. 
The use-def relation between phis is mainly "forwards" (i.e. from phis with
smaller IDs to ones with larger IDs), so the fixed point computation terminates
faster when iterate through the phis in a "backwards" manner. This is quite
visible in complex Mandreel-generated code, where a few hundred phis with
non-trivial use-def chains are generated.

2c8680cc46 Avoid size increase of snapshot. 
The prototype of builtin functions is already unwritable, so we don't
have to make it so (the default map for functions changes after builtins
are initialized).

We no longer need to make the prototype non-extensible, since all properties
that are ever read by the bultins code has been added and frozen already.
Adding properties to the prototype, or changing its __proto__, cannot affect
code.

Removing these two pieces of initialization code reduces the snapshot size
by a few Kb.

We have to emit code for declarations later into the body block
(and not into the start block) so that the environment contains
the correct values.

In order to capture the environment effect of the declarations
that generate code (function declarations) I inserted a separate
AST id and a HSimulate after the declarations are visited.

Also fixes handling deopt in named function expressions:

4084e698c3 Fixed a bug in the chaining of fixup position 
The ARM and MIPS assemblers had a bug where they did not handle the last element
in the list of code positions correctly during the fixup of offsets for forward
jumps. This happened when the first instruction contained a forward jump to a
label, and that label was used in a forward jump later, too.

Unified the code for Assembler::next on ARM and MIPS while we were there.

Added test cases, even for ia32/x64, which seem to be correct, even I don't
fully understand why... %-}

9e2db4c0f0 MIPS: Fix KeyedStoreStubCompiler::GenerateStoreFastDoubleElement() 
Test regress-91013.js (to ensure that the stored value was returned) passed on mips
without this fix, since the input value (in value_reg, a0) also happens to be in
mips return value register v0 at the time of call.

But it is fragile to depend on that behavior, so an explicit move from a0 to v0
is warranted. This fix puts that move in the delay slot of the Ret().

Patch by Paul Lind.

a546e4a8dd Fixed bool <-> Executability confusion and improved typing a bit. 
Passing a value of type Executability to a function expecting a bool worked only
by accident (because of the order of values in the enum). But using boolean
parameters is often a bad idea, anyway, so we use Executability directly.

Just another example why implicit type conversions in C++ are a bad idea... :-P

This improves our static type information by calculating the result type
of conversions (HChange) during range analysis. It allows e.g. to eliminate
the write barrier in the following example where it was not possible before:

function f(x) {
  var y = x + 1;
  if (y > 0 && y < 100) {
    a[0] = y;
  }
}


* Fix bug in Range::Copy. The minus-zero flags has to be preserved by default.

633e615b89 Improve memory usage of receiver type feedback. 
Some AST nodes (Property, Call, etc.) store either a list of receiver
types or a monomorphic receiver type. This patch merges the two fields
using a small pointer list. GetMonomorphicReceiverType() is now a
purely convenience function returning the first and only recorded
type.

This saves about 500K (of about 39M) on average when compiling V8
benchmark as measured by a simple patch adding a zone allocation
counter (https://gist.github.com/1149397).

808748b44d Do not use deprecated ARM instructions in DirectCEntryStub::GenerateCall. 
Non-ancient versions of the ARM-ARM explicitly deprecate most uses of the PC
within instructions and older ARM implementations have a non-predictable offset
(8 or 12) for some of these deprecated uses. Avoiding the deprecated instruction
costs us one additional instruction in DirectCEntryStub::GenerateCall, but this
should not cause any significant performance degradation.

The deoptimizer still uses the PC in a stm instruction, but it is a bit unclear
what to do about that, so simply a comment has been added to reconsider this in
the future.

06bea35f7f Simplify and optimize ToBoolean handling. 
Changing our builtin JavaScript code slightly, we can make sure that we never
see internal objects as arguments for ToBoolean at runtime. Removing that case
from the stub generator and crankshaft makes things a lot easier.

Heap numbers can never be undetectable (only strings and spec objects can), so
we can leave out a useless test.

Try to re-use a non-null register value when returning 'true' in some cases.

Removed special handling of the 'handle all' case, it will very probably never
happen in real code and only makes things more complicated.

Improved naming of the ToBoolean stubs a bit, reflecting the order in which
cases are handled in the code itself.

b625ce2b6b Fix a bug in scope analysis. 
When recompiling code (e.g., when optimizing) we could incorrectly hoist
some function expressions.  This leads to incorrect results or a crash.  The
root cause was that functions were not correctly categorized as expression
or declaration at parse time.

This requires some extra hoops to prevent the print name "anonymous" for
functions created by 'new Function' from establishing a binding.

bdf6895bb3 Encapsulate element handling into a class keyed on ElementsKind 
Advantage is that it's much easier to add new element types (like FAST_SMI_ELEMENTS), and that handling logic for each element kind is (more) consolidated.

Currently, only GetElementsWithReceiver uses the new encapsulation, but the goal is to move much more element functionality into the class incrementally.

Reapply r8783 with an additional fix.

Because the preparser and parser do not use the same scope analysis to
determine if a function can be lazily compiled, the parser can have false
positives.  Rather than treating this as a parse error, treat the preparser
as authoritative and eagerly compile the function.

6f6c882e19 Fixed code generation for LBranch on ARM when the operand's representation is double. 
The condition code for branching on the result of vcmp was wrong, effectively
swapping the true/false branches.

e48ec1c4bd Use type info for the ToBoolean translation in crankshaft. 
To do this, the Branch instruction needs to carry around a temporary register,
but only when the crankshafted code will make a map access. When the
crankshafted code sees an object of a type it hasn't encountered before, it will
always trigger a deopt. Another option in theses cases would be calling a
ToBooleanStub which can handle all types, but then one has to be careful to
*not* trigger a GC (which is currently a bit tricky to achieve).

Const-corrected ToBoolean::Types. Moved the NeedsMap logic into ToBoolean::Types
itself, where it belongs.

This patch improves a lot of benchmarks, crypto-orig even by 16.7%, but slows
down others. The slowdown has to be investigated, but I'd like to get this patch
out first to fix the flakiness problems we currently have due to the previous
crankshafted ToBoolean.

73f8cec70e Do not explicitly record undetectable objects in the ToBoolean stub. 
Loading the map within the stub already implies a check for an undetectable
object, so there is no need to record this separately. Furthermore, this brings
the size of the type info to record down to 8 bits, removing the need to find a
place for the ninth bit in the Code object. ;-)

f7138b1427 Implement a type recording ToBoolean IC. 
The IC records the set of types it has seen, e.g. {String} or {Boolean,
Undefined}, etc.  Note that in theory this could lead to a large number of
different ToBoolean ICs (512, to be exact, because we distinguish 9 types),
but in practice only a small handful of them are actually generated.

Currently the type recording part is only implemented on ia32, other platforms
continue to work like they did before, though.

Removed some dead code on the way.

85f5afb717 Correctly mark functions from our natives files during compilation. 
When creating a CompilationInfo we always have the script and can
determine if it is a natives script.

Now that all natives functions are recognized as such, many of them
are called with undefined as the receiver. We have to use different
filtering for builtins functions when printing stack traces.

Also, fixed one call of CALL_NON_FUNCTION to be correctly marked as a
method call (with fixed receiver). Now that CALL_NON_FUNCTION is
marked as a native function this caused the receiver to be undefined.

615add8463 Expose APIs for detecting boxed primitives, native errors and Math. 
While implementing structured clone I found that I need support
for detecting and creating objects using the builtin Number, String
and Boolean constructors; this CL adds this support. I also need
to be able to detect entities of "native object type (e.g., Error)",
hence the new IsNativeError() calls.

(ref: http://www.whatwg.org/specs/web-apps/current-work/multipage/urls.html#safe-passing-of-structured-data)

dbf0aee6ae simplification to HClampToUint8 
* src/hydrogen-instructions.h (HClampToUint8): Don't mark as having
  flexible representation; instead the output is always an Integer32.
  There is no input representation restriction, so we can still perform
  input-specific truncation.

I tested by looking at the --print-code of

var a = PixelArray(1000000)
function fill(a,x) { for (var i=0; i<a.len; i++) a[i] = x; }

Seems to optimize fine both for double and integer inputs.  But perhaps
there is a better test, for which the original code does better, and
this is a bogus patch.

620d50af55 Avoid patching code after the call to binary operation stub in optimized code 
This patch just adds a nop after the call to the binary operation stub in optimized code to avoid the patching for the inlined smi case used in the full code generator to kick in if the next instruction generated by the lithium code generator should accidentially enable that. For calls generated by CallCodeGeneric this was already handled on Intel platforms, but missing on ARM.

On IA-32 I did also try to check for whether the code containing the call was optimized (patch below), but that caused regressions on some benchmarks.

5528ce7057 MIPS: Cleaned up calling-related methods in the assembler. 
Patterned after r8482, Cleaned up calling-related methods in the ARM assembler.

On MIPS I completely refactored the Jump and Call methods.
All the Jump and Call macro helpers have been replaced with overloaded functions
(matching the ARM version) and using default parameter values where possible.
The previously mostly-unused CallSize function is utilized as well (same as on ARM).
The unused Jump(Operand, ...) and Call(Operand, ...) versions have been completely removed.
I also removed the Jump(BranchDelaySlot, ...) and Call(BranchDelaySlot,...) methods as
they were unused and declaring them would either result in a lot of unused code or the
previously experienced macro-hell. The only exception to this is for Ret() where the
branch delay slot is often used.

This fixes the failing debug tests for example cctest test-debug/DebugStepFor.

The approach is different from the normal function code flusing. Here

10bb16f495 Add support for lazy deoptimization from deferred stack checks 
The debugger can be entered from the deferred stack check in optimized code. This can cause both lazy deoptimization and debugger deoptimization (setting the first break point and inspecting the stack for optimized code respectively). This required deoptimization support from the deferred stack check.

The lazy deoptimiztion call is inserted when the deferred code is done including restoring the registers. The bailout to the full code is the begining of the loop body as that is where the stack check is sitting in the optimized code. The bailout is not to the stack check in the full code as that is sitting at the end of the loop.

Context is still used from the stack from in CallKnownFunction (this seems safe), and in CallRuntimeFromDeferred in lithium-codegen-ia32.cc, which needs to be fixed.
