be20c55b3e Change RegExp syntax to fail on invalid ranges like [\d-x], [x-\d] and [\d-\d]. 
The previous behavior was to treat the "-" as verbatim if the range was invalid.
This change matches the JSC changeset http://trac.webkit.org/changeset/72813/

7be18f702b make DateParser::TimeComposer handle 1-2 digits millisecond values 
see http://code.google.com/p/v8/issues/detail?id=944
This patch makes DateParser::TimeComposer process times that have
millisecond values with only 1 or 2 digits.

Without this patch, Date.parse("2010-11-25T22:02:30.5") returns
1290690150005 and
Date.parse("2010-11-25T22:02:30.5") == Date.parse("2010-11-25T22:02:30.005")
evaluates to true.

With this patch, Date.parse("2010-11-25T22:02:30.5") returns
1290690150500 instead, and
Date.parse("2010-11-25T22:02:30.5") == Date.parse("2010-11-25T22:02:30.005")
evaluates to false.

d46fb9d454 New attempt to make the allocation routines 64 bit clean. 
This one has been approved by the 64 bit compiler in MSVC
2005 so I hope it also passes the 2008 version.

The --max-new-space-size option is now in kBytes.
The --max-old-space-size option is now in MBytes.

Some issues remain with 64 bit heaps and the counters.  See

Currenly the constructor like this:

creates a map with duplicate desciptors which is bad in many ways.

7672338bc9 Fixes bug in Object.freeze and Object.seal causing them to misbehave when Array.prototype has changed. 
Object.freeze and Object.seal uses GetOwnPropertyNames which
returns an array with local property names. This array will also have
the additional properties defined on Array.prototype or
Object.prototype.

Note that, the implementation of GetOwnPropertyNames (when used as
Object.getOwnPropertyNames) is correct, since the spec says to create
a new Array (which would also have these properties).

8e0cd6db8a Handle overwriting valueOf on String objects correctly when adding 
This adds a check to the fast case string add to ensure that the String object still have the default valueOf function. The default valueOf is sitting on a hidden prototype of String.prototype.

Before using the fast case valueOf the object is checked for a local valueOf property. For slow case objects this check always reports true (the dictionary is not probed, so valueOf might be there) and for fast case objects the descriptor array is checked for the valueOf symbol (just liniar scan). After that the prototype is checked for beeing the initial value of String.prototype. If this all pass (that is the default valueOf is still in place) this result is cached on the map making the check fast the next time.

This is only implemented in the optimizing compiler, as the two usages of %_IsStringWrapperSafeForDefaultValueOf is never hit by the full compiler.

I will port to x64 and ARM when this has been reviewed for ia32.

I will remove the performance counters prior to final commit.

stub and calculate the answer.  This eliminates the need to call
both the rest of the binary op and the patching runtime call.  The

while we are patching the binary op ICs.

c56b92d65d This change allows generating call-stubs for objects with normal (non-fast) objects in the prototype chain. StubCompiler::CheckPrototypes does ne 
If the top level object is a normal object the stub is stored in its prototype map.

Lookup result of type NORMAL is not covered (since the normal stub currently doesn't check the prototype chain).

97ecc50377 ARM: Correctness fix to Math.pow optimization 
The change in r4990 contained a bug in Math.pow when then exponent was a large negative smi. In that case calculating 1/Math.pow(x,-y) did not provide the correct result as Math.pow(x,-y) would overflow ti infinity. This was caught by Sputnik test S8.5_A13_T1.

6044b33766 Implement IC for storing to dictionary case objects. 
The IC stub is completely generic, so there will only be one such stub
in the system.

Added a new overloaded version of the macro assembler RecordWrite
method for cases where we have the address we store to computed up
front.

ff6c4fe680 ARM: Special code for raising to the power of an integer 
When calculating Math.pow where the exponent is a smi use a simple loop to calculate the result.

Added support for the vmov instruction moving from one doubleword extension register to another.

Added some Math.pow tests which partially covers what is in the Sputnik tests.

65018d9123 ARM: Use the vsqrt instruction when available 
vsqrt is used to calculate Math.sqrt(x), Math.pow(x, 0.5) and Math.pow(x, -0.5). Code size doesn't matter, as %_MathSqrt and %_MathPow are only called in one place each.
