      [tools][system-analyzer] Add profiler-panel · 7a90c320
      Camillo Bruni authored
      Add basic profiler support
      - Moved profiling-related helpers to profiling.mjs
      - Added bottom-up profiler table
      - Added mini-timeline overview wit opt/deopt events and usage graph
      - Added flame-graph, pivoted on the currently selected function
      
      Drive-by-fixes:
      - Added/updated jsdoc type information
      - Fixed static symbols (builtins, bytecodehandlers) that were both
        added by the CppEntriesProvider and from code-events in the v8.log
      - Support platform-specific (linux/macos) dynamic symbol loader by
        adding a query path ('/v8/info/platform') to lws-middleware.js
      - added css var --selection-color

      - Parse the condensed source position info support for jitted code
      - Add progress bar/circle to loader
      - Use temporary Array instead of concatenated strings in escapeField to
        reduce gc pressure
      - Use bound functions as event handlers in more places
      - Various timeline legend fixes:
        - Fix columns alignment when duration is present
        - Use fixed width to avoid breaking the UI
        - Correctly show total/percents for 'All' and 'Selection' entries
        - Improve usability of filtering buttons: added tooltips and fixed
          redrawing on filtering

      Profiler:
        - Track profiler tick durations
        - Various speedups due to low-level hacking
      Improve code-panel:
        - Better register highlighting
        - Added address navigation and highlighting
        - Removed obsolete inline source-view
      Improve script-panel:
        - Keep current source position focused when showing related entries
        - Better tool-tip with buttons to focus on grouped entries per
          source postion
        - Focus by default on other views when showing related entries
      Improve timeline-panel:
        - Initialise event handlers late to avoid errors
        - Lazy initialise chunks to avoid errors when zooming-in and trying to
          create tooltips at the same time

      [system-analyzer] Add source map support · 18bcc9a6
      Leszek Swirski authored
        - Asynchronously load source map from sourceMappingURL
        - Once loaded, annotate source positions with their original position
        - Update script panel tooltip to include link to original source
           - For the above, make DOM.element a slightly more flexible API,
             allowing defining attributes and children
           - Also fix ToolTipEvent handling to support nodes.
        - Shuffle around some code to make createScriptNode async, in case
          we want to load the source map when building the script node itself.
        - Drive-by: make source markers a simple backgroundColor when there is
          only one group.
