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.

This is the first step in the MIPS port of V8. It adds assembler, disassembler and simulator for the MIPS32 architecture. Contains stubbed out implementation of all the compiler/code generator infrastructure to make it all build. Patch by Alexandre Rames from Sigma Designs Inc. This is the landing of http://codereview.chromium.org/543161.

platform dependent ifdefs is useless if it does not include an error like this. You will end up searching for the failure in all the wrong places.

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.

- TARGET, the architecture we will generate code for. This is brought it from the build system. - HOST, the architecture our C++ compiler is building for. This is detected automatically based on compiler defines. This adds macros for 32 or 64 bit, and cleans up some include conditionals, etc. Review URL: http://codereview.chromium.org/99355 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@1864 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

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

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.

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
