Jakob Kummerow d180d40d28 [wasm][devtools] Fix reported function body offsets
The DevTools frontend doesn't want the Wasm module's understanding of
function body offsets (i.e. including locals), but the ranges of
offsets where breakpoints can be set (i.e. only where instructions are).
This patch adjusts the reported offsets accordingly.
A consequence is that we have to report full (start,end) pairs for each
function, instead of being able to dedupe end1==start2 etc.

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.
