      [inspector] Introduce v8::StackFrame::GetLocation() API. · ed7b6640
      Benedikt Meurer authored
      This introduces a new `GetLocation()` method for `v8::StackFrame`s,
      which returns both line and column number at the same time (using the
      existing `v8::Location` class). Since `v8::StackFrame` instances store
      only the source position (per https://bit.ly/v8-stack-frame), we
      currently need to look up the source position in the Script's line table
      twice, once when we request the line number, and another time when we
      request the column number.
      
      With `GetLocation()` we perform only a single lookup in the Script's
      line table and return both line and column number at the same time. This
      cuts roughly 8% of the average execution time from the `standalone.js`
      benchmark mentioned in crbug.com/1280519.

      Reland "[include] Split out v8.h" · ec06bb6c
      Dan Elphick authored
      This is a reland of d1b27019
      
      Fixes include:
      Adding missing file to bazel build
      Forward-declaring classing before friend-classing them to fix win/gcc
      Add missing v8-isolate.h include for vtune builds

      [include] Split out v8.h · d1b27019
      Dan Elphick authored
      This moves every single class/function out of include/v8.h into a
      separate header in include/, which v8.h then includes so that
      externally nothing appears to have changed.
      
      Every include of v8.h from inside v8 has been changed to a more
      fine-grained include.
      
      Previously inline functions defined at the bottom of v8.h would call
      private non-inline functions in the V8 class. Since that class is now
      in v8-initialization.h and is rarely included (as that would create
      dependency cycles), this is not possible and so those methods have been
      moved out of the V8 class into the namespace v8::api_internal.
      
      None of the previous files in include/ now #include v8.h, which means
      if embedders were relying on this transitive dependency then it will
      give compile failures.
      
      v8-inspector.h does depend on v8-scripts.h for the time being to ensure
      that Chrome continue to compile but that change will be reverted once
      those transitive #includes in chrome are changed to include it directly.

      Add a convenience method to get the debugged context · 37394eb3
      jochen authored
      Since the generic GetCallingContext is deprecated, but there's still the
      use case for the debugger to get the currently debugged context while in
      the debug context, add a convenience API for it.
      
      Note that EventDetails already exposes this context, but the embedder
      might not necessarily have the EventDetails around.
