when the left operand lets us shortcut the computation.

1c89cef32d Make strict equality checks faster on IA32 by doing
more work in the CompareStub. I'll port this to ARM
once I'm satisfied with the performance improvements.

- Set the name of C++ callback functions.
- Clean up a couple of out-dated comments related to literal creation.

6974e4b2c7 Fixed bug #57. Introduced String::Utf8Value and replaced a bunch of
uses of String::AsciiValue with String::Utf8Value.  Fixed shell sample
'load' so it doesn't print error messages.

968facb9ff - Fixed issue when building samples and cctests on 64-bit machines.
- Fixed mozilla test breakage caused by python's obscure module
  loading rules.
- Made sure test.py propagates test failures out as the exit code of
  the script.
- Remove runtime calls to get number constants. Remove Heap roots for
  some special numbers.
- Fix typo in accessors.h.
- Changes CopyMap to not copy descriptors.  Adds
  CopyMapRemoveTransitions that copies non-transition descriptors.
  Changes interface of DescriptorArray::Copy operations to simplify
  them.

c42f5829a1 Included mjsunit JavaScript test suite and C++ unit tests.
In the shell sample don't print the result of executing a script, only
evaluating expressions.

Fixed issue when building samples on Windows using a shared V8
library.  Added visibility option on Linux build which makes the
generated library 18% smaller.

Changed build system to accept multiple build modes in one build and
generate seperate objects, libraries and executables for each mode.

Removed deferred negation optimization (a * -b => -(a * b)) since this
visibly changes operand conversion order.

Improved parsing performance by introducing stack guard in preparsing.
Without a stack guard preparsing always bails out with stack overflow.

31e7138e1a Improved performance of garbage collection by changing the way we use the marking stack in the event of stack overflow during full garbage collection and by changing the way we mark roots.
Cleaned up ARM version by removing top of stack caching and by introducing push/pop elimination.

Cleaned up the way runtime functions are called to allow runtime calls with no arguments.

Changed Windows build options to make sure that exceptions are disabled and that optimization flags are enabled.

Added first version of Visual Studio project files.

769cc962a0 Improved performance of unary addition by avoiding runtime calls.
Fixed the handling of '>' and '<=' to use right-to-left conversion and left-to-right evaluation as specified by ECMA-262.

Fixed a branch elimination bug on the ARM platform where incorrect code was generated because of overly aggressive branch elimination.

Improved performance of code that repeatedly assigns the same function to the same property of different objects with the same map.

Untangled DEBUG and ENABLE_DISASSEMBLER defines.  The disassembler no longer expects DEBUG to be defined.

Added platform-nullos.cc to serve as the basis for new platform implementations.
