Start a local symbol server using the local-web-sever node package: ws --stack system-analyzer/lws-middleware.js lws-static cors The system-analyzer will then use it to symbolize profiles. Note: The symbol server will execute `nm` and `objdump` locally.

- In log.cc, we used InstructionStart() for code create events, but the Code object address for code move events. Change to use InstructionStart() for both. - The symbol table contains some kind of virtual address, not file offsets. They happened to be identical in the past but are no longer, probably due to toolchain changes. Now we use objdump to figure out the difference between virtual addresses and file offsets. - When a new code object happened to be created at the same address as a previous one, we wouldn't update it. This is indeed wrong, as predicted in a TODO by Jaro. - For 64bit addresses, using >>> is wrong, now replaced with division.

On Android we load the native library directly from the APK. As such, we need to convert symbols from the mapped APK to the underlying .so when symbolizing the ticks. This CL adds a --apk-embedded-library argument to tick processor to enable specifying which unstripped library file was embeded in the APK and enable symbolizing.

(1) --prof-cpp: Collects ticks like --prof, but ignores code creation events to reduce distortion (so all JS ticks will be "unaccounted"). Useful for profiling C++ code. (2) --timed-range flag for tick processor: Ignores ticks before the first and after the last call to Date.now(). Useful for focusing on the timed section of a test.

Added a console parameter for source map to the tick processor. The tickprocesspor reads in the source maps and uses it to output the original filename, line number and column in the profile. Modified d8 to output column numbers into the log, since this is needed to do source mapping.

As this is only needed for internal profiling (not for DevTools), the following approach had been chosen: - during snapshot creation, positions of serialized objects inside a snapshot are logged; - then during V8 initialization, positions of deserealized objects are logged; - those positions are used for retrieving code objects names from snapshot creation log, which needs to be supplied to tick processor script. Positions logging is controlled with the new flag: --log_snapshot_positions. This flag is turned off by default, and this adds no startup penalty. To plug this fix to Golem, the following actions are needed: - logs created using 'mksnapshot' need to be stored along with VM images; - tick processor script needs to be run with '--snapshot-log=...' cmdline argument.

instead of normal JSObjects. This ensures that __proto__ and accessors on the Object prototype do not interfere with catch scopes. Also, it fixes the bug that catch variables were not DontDelete (issue 74). Next step is to create special lookup routines for context extension objects and remove the special handling of context extension objects from the general javascript object lookup routines.

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. git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@16 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
