      Custom objdump to enable perf annotation · dbba4b40
      mattloring authored 
      Allows jitted code to be annotated in perf. To use:

1) Report generated code in code-(pid)-1.asm.

  perf record -- d8 --print-code --redirect-code-traces script.js

2) Run perf report from the directory containing the above code file.

  perf report --objdump=v8/tools/objdump-v8

This script supports generated code from both crankshaft or turbofan.

      [interpreter] Add relative numbers to dispatch report · a3f598fc
      klaasb authored 
      This adds an additional column with percentages to the output of
bytecode_dispatch_report.py --top-dispatches-for-bytecode.
The percentages always represent the relative number of dispatches to
the target bytecode to all dispatches from the source bytecode.
The additional flag --sort-sources-relative/-r allows sorting the
"Top sources of dispatches to" the given bytecode by this column to more
easily find bytecodes that significantly often dispatch to the target.

      [turbolizer] Show a label with a shorter parameter for some opcodes. · feb93dd6
      bgeron authored 
      With this patch, every node in turbo-*.json has an opcode, a title, and
a label. The label field is new; the opcode and title were already
there. The title is for the mouseover text. The label is what will be
displayed in the graph view, unless it's too long, in which case only
the opcode will be displayed. (This is similar to the preexisting
behaviour of putting titles in labels, except that the titles were
rarely short enough to fit in a label.)

With this patch, the labels generated are in practice the same as the
titles we had before, except for LoadField and StoreField, which will be
rendered as LoadField[[+432]] and StoreField[[+432]] (if 432 was the
offset).

This diff adds an overloadable method

    virtual void Operator1<T>::PrintParameter(ostream&, PrintVerbosity)

for each type T to Operator1. Its default implementation just uses
operator<<(ostream&, T const&) and adds square brackets around it, but
it is overridden for FieldAccess to print "[+432]" in the example case.

      [turbolizer] Improve code comments in disassembly · 7f162dbc
      Alexander.Gilday2 authored 
      This change analyzes and links the output of --code-comments in the disassembly view within turbolizer with the other views, such that selecting these comments will also select the respective blocks/lines/nodes within the other views. The block start comments (e.g. -- B4 start --) are linked with the blocks in the schedule phase view and vice versa. The source position comments (e.g. -- primes.js:3:10 --) select the respective spans, lines, and nodes in the JavaScript code view, the schedule phase view, and the other compilation phase views respectively, and vice versa. It also modifies the display of the line and column numbers in the source position comments to be offset from 1 instead of 0 and ignore the initial source position of the first line of code (from removal of the function name in the compiler).

Also fixed the bug where previous selections weren't being cleared properly across multiple views, adding appropriate clear calls when using the selection broker.

      [swarming] Port updated version of isolate_driver.py · 77fbb1c3
      machenbach authored 
      This version of the isolate_driver includes a feature
that automatically derives shared libraries for inclusion.

This is needed for GN as the shared library location is
different compared to gyp and having different configs
would be tedious.

This also removes the shared-library-specific configs as
they are no longer needed with the new driver.

      gdb-v8-support.py: Fix old style print statement · c52685a5
      honggyu.kp authored 
      Since python3 does not use the old print statement, it may not be able
to load gdb-v8-support.py script in gdb as below:

  (gdb) source tools/gdb-v8-support.py
    File "tools/gdb-v8-support.py", line 170
      print result
                 ^
  SyntaxError: Missing parentheses in call to 'print'

This fixes print statement for both python2 and python3.

      [turbolizer] Features and bug-fixes · e52907f8
      danno authored 
      Fix bugs and add a few small useful features:

* Fix Schedule view to properly parse schedule output and respond to switching
  back to graph views.
* Add shorcuts for showing edges of selected nodes.
  - 'i' shows all inputs
  - 'o' shows all outputs
  - '1'-'9' shows all nodes nth input where 1 <= n <= 9
  - 'c' shows all control inputs
  - 'e' shows all effect inputs
* Holding the control key down when using a edge-showing shortcut toggles edge
  state rather the just showing.
* 'a' selects all nodes in graph view.
* Node selection is preserved between graph views and Schedule views.
* Holding control key down when using regular expression search shows currently
  hidden nodes that match the regex search.
* Pane expansion buttons now respond to clicks in entire button area.
* Default text in regex search box makes searching more discoverable.
