Seth Brenith 3a558456a9 [v8windbg] Skip undefined types in Torque structs 
The test cctest/test-v8windbg recently started failing because the
v8windbg debugger extension is unable to read the "flags" field on a
SharedFunctionInfo instance. This occurs because one of the bitfields
within "flags" has type OSRCodeCacheStateOfSFI, which is only declared
using an "opaque enum declaration":

  enum OSRCodeCacheStateOfSFI : uint8_t;

When WinDbg fails in its attempt to look up that type, v8windbg responds
by failing to construct anything at all for "flags". However, the other
17 bitfields in "flags" can be represented successfully, so a more
useful behavior is to just skip the one failed entry.

TOOLS

This directory contains debugging and investigation tools for V8.

The contents are regularly mirrored to http://v8.dev/tools.

Local Development

For local development you have to start a local webserver under http://localhost:8000:

  cd tools/;
  npm install;
  ws;

Local Symbol Server

The system-analyzer can symbolize profiles for local binaries by running a local symbol server

  cd tools/;
  ws --stack system-analyzer/lws-middleware.js lws-static cors;

Note that the local symbol server will run nm and objdump and has access to your files.
