-----------
[JSC] Add LLDB debugging infrastructure for WebAssembly (single VM)
https://bugs.webkit.org/show_bug.cgi?id=299214
rdar://160971785
Reviewed by Keith Miller.
This patch introduces a WebAssembly debugging solution that enables LLDB
debugging
of WebAssembly code running in JavaScriptCore's IPInt tier through the GDB
Remote
Serial Protocol. Currently supports single VM debugging scenarios.
Key components:
- WasmDebugServer: TCP server implementing GDB Remote Protocol
- Virtual address space management for LLDB compatibility
- Breakpoint and stepping support for WebAssembly bytecode
- Memory inspection and call stack visualization
- Comprehensive test framework with parallel execution
For detailed architecture and usage information, see:
