This changelist makes the GDB-stub actually execute GDB-remote commands, by accessing the Wasm engine state. More precisely: - class GdbServer registers DebugDelegates that receive debug notifications when a new Wasm module is loaded, when execution suspends at a breakpoint or for an unhandled exception. - Since the GDB-remote commands arrive on a separate thread, all queries from the debugger are transformed into Task objects, that are posted into a TaskRunner that runs in the Isolate thread. - class WasmModuleDebug contains the logic to retrieve the value of globals, locals, memory ranges from the Wasm engine and to add/remove breakpoints. Build with: v8_enable_wasm_gdb_remote_debugging = true Run with: --wasm-gdb-remote Test with: python tools\run-tests.py --outdir=out\debug_x64 debugging -j 1 Bug: chromium:1010467 Change-Id: I9703894620a027d3c920926db92e2ff809d84ab8 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1941139 Reviewed-by: Benedikt Meurer <bmeurer@chromium.org> Reviewed-by: Clemens Backes <clemensb@chromium.org> Commit-Queue: Paolo Severini <paolosev@microsoft.com> Cr-Commit-Position: refs/heads/master@{#67412}
