Hao Xu 024e5fb4fa [CSA][codegen] Add BitcastElision Phase 
Turbofan generates bitcast nodes like BitcastWordToTaggedSigned to
ensure the value types of definitions and uses are matched. These
nodes can be elided after MachineGraphVerifier verifying the graph.
This can avoid generating redundant instructions:

Before:
  xorl r15,r15
  cmpl [rdx+0xb],r15

After:
  cmpl [rdx+0xb],0x0

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.
