Support profiler stack sampling in any situation. After this change, almost all profiler ticks (except GC ones) have a stack sample data associated. Tested under Linux, OS X, and Windows.

JavaScriptFrameIterator is templatized on the iterator type and renamed to JavaScriptFrameIteratorTemp. The original JSFI is now a typedef for JavaScriptFrameIteratorTemp<StackFrameIterator>. Because of templatizing, JSFI code is moved to frames-inl.h StackTraceFrameIterator moved to frames.* Implemented SafeStackFrameIterator which wraps StackFrameIterator and have the same interface. It performs additional checks of stack addresses prior to delegating to StackFrameIterator. SafeSFI is used in an another specialization of JavaScriptFrameIteratorTemp template to perform safe JS frames iteration on sampler ticks. I haven't took an advantage of having multiple stack frames in tickprocessor yet.

- Pass the knowledge whether the old GC is compacting to the GC prologue and epilogue. This allows us to skip frame cooking and uncooking when doing a mark-sweep GC. - Add the ability for the code to refer to its code object by adding a handle to the code object in the MacroAssembler.

the trampoline frames introduced for invoking functions through the new keyword. Review URL: http://codereview.chromium.org/7223 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@485 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

- Simplified frame entry and frame exit code. - Added ArgumentsAdaptorTrampoline and check for matching argument counts in the InvokePrologue. - Removed definition and uses of USE_OLD_CALLING_CONVENTIONS. - Changed MacroAssembler::InvokeBuiltin to match ia32 version. - Start introducing convenience instructions in the ARM assembler as needed. These instructions take all Register parameters to avoid extra typing of "Operand(reg)". To keep the architectures in sync these changes have been made to the ia32 files: - Changed MacroAssembler::EnterFrame(StackFrame::Type type) to MacroAssembler::EnterInternalFrame(). These parts are still missing: - unimplemented: Builtins::Generate_FunctionApply - large limit - unimplemented: Builtins::Generate_ArgumentsAdaptorTrampoline - non-function call - The files have not been lint'd yet.

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. git-svn-id: http://v8.googlecode.com/svn/trunk@13 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

Added a few samples and support for building them. The samples include a simple shell that can be used to benchmark and test V8. Changed V8::GetVersion to return the version as a string. Added source for lazily loaded scripts to snapshots and made serialization non-destructive. Improved ARM support by fixing the write barrier code to use aligned loads and stores and by removing premature locals optimization that relied on broken support for callee-saved registers (removed). Refactored the code for marking live objects during garbage collection and the code for allocating objects in paged spaces. Introduced an abstraction for the map word of a heap-allocated object and changed the memory allocator to allocate executable memory only for spaces that may contain code objects. Moved StringBuilder to utils.h and ScopedLock to platform.h, where they can be used by debugging and logging modules. Added thread-safe message queues for dealing with debugger events. Fixed the source code reported by toString for certain builtin empty functions and made sure that the prototype property of a function is enumerable. Improved performance of converting values to condition flags in generated code. Merged disassembler-{arch} files. git-svn-id: http://v8.googlecode.com/svn/trunk@8 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
