the code object's instructions. This allows us to find a code object using just the pc. This approach uses a cache (PcToCodeCache) to make sure we don't continuously have to iterate heap pages. This change eliminates the need for cooking and uncooking of stack frames.

The live registers are now only stored to the expression stack with the non pointer values being stored as smis (on the 32-bit platforms these values are assumed to be 31-bit max). This makes the CEntryStub entry/exit code much simpler, and there is no longer any need for a mode (debug or normal) on it. Fix a missing live register when breaking at ARM keyed load.

Chromium build. v8.gyp no longer sets any V8_TARGET_ARCH_* macro on the Mac. Instead, the proper V8_TARGET_ARCH_* macro will be set by src/globals.h in the same way as the V8_HOST_ARCH_* macro when it detects that no target macro is currently defined. The Mac build will attempt to compile all ia32 and x86_64 .cc files. #ifdef guards in each of these target-specific source files prevent their compilation when the associated target is not selected. For completeness, these #ifdef guards are also provided for the arm and mips .cc files. BUG=706 TEST=x86_64 Mac GYP/Xcode-based Chromium build (still depends on other changes) Review URL: http://codereview.chromium.org/2133003 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@4666 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

As I discovered that JSFrame accesses SharedFunctionInfo only to calculate caller SP and the latter is not used in profiler's stack sampling, I disabled accessing heap objects in JSFrame when doing stack sampling. This finally made V8's profiling stable when used from Chrome on a real web app. Review URL: http://codereview.chromium.org/73020 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@1694 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

- 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.

- 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.

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
