      [wasm][debug] Implement instrumentation breakpoints · 15f3392a
      Clemens Backes authored
      This CL adds support for instrumentation breakpoints in wasm. The
      request for "break on entry" is set on the script, and we need to keep
      it stored there because there might not be any instances of that wasm
      module yet. Once instances get created, the flag value is transferred to
      all instances. The flag stored there is then checked in the function
      prologue in Liftoff debugging code. This ensures that we will stop at
      the first valid break position in any function within that module.
      Hitting that instrumentation breakpoint will then clear the flag from
      the script and from all other live instances (in the same isolate).
      
      A first basic test is contained in this CL. More tests will be added
      later.

      [torque] generate C++ class definitions per Torque file · 03f60296
      Tobias Tebbi authored
      This CL splits the class definitions per .tq file, to realize the
      following relationship:
      A class defined in src/objects/foo.tq has a C++ definition in
      src/objects/foo.h. Torque then generates:
      
      - torque-generated/src/objects/foo-tq.inc
        An include file (no proper header) to be included in src/objects/foo.h
        containing the Torque-generated C++ class definition.
      
      - torque-generated/src/objects/foo-tq-inl.inc
        An include file (no proper header) to be included in
        src/objects/foo-inl.h containing inline function definitions.
      
      - torque-generated/src/objects/foo-tq.cc
        A source file including src/objects/foo-inl.h that contains non-inline
        function definitions.
      
      Advantages of this approach:
      - Avoid big monolithic headers and preserve the work that went into
        splitting objects.h
      - Moving a definition to Torque keeps everything in the same place
        from a C++ viewpoint, including a fully Torque-generated C++ class
        definition.
      - The Torque-generated include files do not need to be independent
        headers, necessary includes or forward declarations can just be added
        to the headers that include them.
      
      Drive-by changes:
      A bunch of definitions and files had to be moved or created to realize
      a consistent 1:1 relationship between .tq files and C++ headers.

      [torque] refactor: use -tq only in filenames derived from .tq files · 64caf2b0
      Tobias Tebbi authored
      This is to establish a naming rule for Torque-generated files:
      - If the file is called foo/bar-tq..., then it is derived from a
        file foo/bar.tq
      - Otherwise it doesn't belong to a specific .tq file.
      
      So far, we attached -tq to all Torque-generated file names, where it
      sometimes corresponded to a .tq file name and sometimes not.
      It is not necessary to add -tq to file names to indicate that they are
      Torque-generated, since they are already in a directory called
      torque-generated, and we always refer to them as
      "torque-generated/filename", so there is no confusion even though some
      files now have the same name as a corresponding hand-written file, for
      example factory.cc.

      [offthread] Unify compiler.cc finalization logic · 58b12f63
      Leszek Swirski authored
      This patch unfies the finalization logic between the various unoptimized
      compilation paths in compiler.cc, taking the various post-processings and
      fixups needed for off-thread finalization and performing them in the same
      order for the other finalizations.
      
      It also unifies the general compilation path between streaming script
      compilation, main-thread script compilation, and main-thread lazy
      compilation, making the main-thread paths both use an iterative execution
      and finalization, and making all three use the same job helper methods
      and overall finalization helper.

      Make --stress-background-compile a V8 flag rather than a d8 flag, so
      that it also tests unittests/cctests.
      
      Now, with this flag, every top-level script compile (that fulfills a
      couple of restrictions) will be both main-thread and background-thread
      compiled, taking the result of the background compile. In the future,
      we'll probably want to verify that the two results are equivalent.
      
      One of the necessary changes to allow tests to pass was to introduce a
      concept of a "temporary" script (with a temporary script id), which
      doesn't get added to the script list. This is to avoid the main-thread
      compile part of the stress-test having a debugger-visible side-effect,
      e.g. in tests that enumerate scripts. We can't just create new ids for
      such scripts, as then script-id expectation files no longer match.

      Introduce REPL mode · fbcc2e87
      Simon Zünd authored
      Design doc: bit.ly/v8-repl-mode
      
      This CL adds a new REPL mode that can be used via
      DebugEvaluate::GlobalREPL. REPL mode only implements re-declaration
      of 'let' bindings at the moment. Example:
      
      REPL Input 1: let x = 21;
      REPL Input 2: let x = 42;
      
      This would normally throw a SyntaxError, but works in REPL mode.
      
      The implementation is done by:
        - Setting a 'repl mode' bit on {Script}, {ScopeInfo}, {ParseInfo}
          and script {Scope}.
        - Each global let declaration still gets a slot reserved in the
          respective {ScriptContext}.
        - When a new REPL mode {ScriptContext} is created, name clashes
          for let bindings are not reported as errors.
        - Declarations, loads and stores for global let in REPL mode are
          now "load/store global" instead of accessing their respective
          context slot directly. This causes a lookup in the ScriptContextTable
          where the found slot for each name is guaranteed to be the same
          (the first one).

      [wasm] Make {Script} object reference {NativeModule} directly. · 9d8aa1a6
      Michael Starzinger authored
      This is a first step towards being able to share the same script for
      multiple {WasmModuleObject} objects. In general it should be possible
      for the inspector to debug (i.e. disassemble, set breakpoints) multiple
      modules if they all have the same URL (and the same wire bytes). These
      are the same conditions under which we can canonicalize the modules to
      be based on the same underlying {NativeModule} as well. Hence it makes
      sense to establish a link from {Script} to {NativeModule} in this CL.
      
      Subsequent CLs will eventually deprecate the {wasm_module_object} field.

      [tracing] Improve tracing signals for compilation/optimization. · a2af7e11
      Benedikt Meurer authored
      This adds OBJECT/SNAPSHOT trace events for Script and SharedFunctionInfo
      objects, logging their creation with appropriate information to make
      sense of them.
      
      Based on that we introduces five flow events to model the optimized
      compilation via tracing in the "disabled-by-default-v8.compile" category:
      
        - "v8.optimizingCompile.start" logs the creation of the
          PipelineCompilationJob (for TurboFan JavaScript optimization)
          with the "function" argument referring to the trace event
          object created for the SharedFunctionInfo.
        - "v8.optimzingCompile.prepare" logs the preparation of the
          PipelineCompilationJob on the main thread, also carrying the
          "function" argument. This connects the flow event to the actual
          tracing duration event associated with the preparation phases.
        - "v8.optimizingCompile.execute" logs the (usually concurrent)
          optimization of the TurboFan graph (again with "function").
        - "v8.optimizingCompile.finalize" logs the main thread phase which
          finalizes the optimized code and eventually installs it (in case
          of success).
        - "v8.optimizingCompile.end" signals the end of the
          PipelineCompilationJob, which carries the "compilationInfo",
          that contains the interesting bits of the OptimizedCompilationInfo,
          specifically whether the compile was successfull and which functions
          were inlined for example.
      
      This also adds two instant events "V8.AbortOptimization" and
      "V8.RetryOptimization" in "disabled-by-default-v8.compile" category
      that are emitted when TurboFan cannot optimize a certain function.
      In case of "V8.RetryOptimization", TurboFan might be able to optimize
      it later, whereas "V8.AbortOptimization" permanently disables the
      optimization of a given function. The JSON representation of this is
      
      ```js
      {
        "pid": 256639,
        "tid": 256639,
        "ts": 6935411377801,
        "tts": 159116,
        "ph": "I",
        "cat": "disabled-by-default-v8.compile",
        "name": "V8.AbortOptimization",
        "dur": 0,
        "tdur": 0,
        "args": {
          "reason": "Function is too big to be optimized",
          "function": {
            "id_ref": "0x600000001",
            "scope": "v8::internal::SharedFunctionInfo"
          }
        }
      },
      ```
      
      where the "function" refers to a previously emitted SNAPSHOT for the
      function in question. In the trace viewer it will show up as instant
      event under "v8.optimizingCompile.prepare" in case of the relevant
      example where optimization is disabled due to reaching the bytecode
      limit (as in the JSON above), i.e. it'll look something like this
      
        https://i.paste.pics/aafc2de9df10ea8f5acc1a761d80f07b.png
      
      for the example highlighted in the recent blog post
      
        https://ponyfoo.com/articles/javascript-performance-pitfalls-v8
      
      that describes the optimization limit. The "v8.optimizingCompile.end"
      duration event will also carry this information as part of the
      "compilationInfo" object, but specifically for CI tools, etc. it might
      be a whole lot easier to just look for the "V8.AbortOptimization"
      instant event.
