[PATCH] D71575: [LLDB] Add initial support for WebAssembly debugging

[Sam Clegg via Phabricator via llvm-commits]

sbc100 added a comment.

I don't know the lldb codebase, but from a webassembly perspective this looks promising.

I suppose we are long way from having a webassebly VM that exports that correct wire protocol to actually test this?



================
Comment at: lldb/include/lldb/Utility/ArchSpec.h:191
 
+    eCore_wasm32,
     kNumCores,
----------------
Add another newline below to the follow the existing grouping pattern?


================
Comment at: lldb/source/API/SystemInitializerFull.cpp:73
 #include "Plugins/ObjectFile/PECOFF/ObjectFilePECOFF.h"
+#include "Plugins/ObjectFile/WASM/ObjectFileWasm.h"
 #include "Plugins/OperatingSystem/Python/OperatingSystemPython.h"
----------------
Can you name this directory "wasm" rather than "WASM" since its not an acronym.   


================
Comment at: lldb/source/API/SystemInitializerFull.cpp:179
   ObjectFilePECOFF::Initialize();
+  wasm::ObjectFileWasm::Initialize();
 
----------------
Why is the namespace needed here for wasm but not the other three above.. seems inconsistent.


================
Comment at: lldb/source/Plugins/DynamicLoader/WASM-DYLD/DynamicLoaderWasmDYLD.h:1
+//===-- DynamicLoaderWasmDYLD.h ------------------------------*- C++ -*-===//
+//
----------------
Again, avoid WASM in the directory name.   I suppose "Wasm" would also be acceptable, but I'm trying to push for "wasm" or "WebAssembly".


================
Comment at: lldb/source/Utility/ArchSpec.cpp:107
+    {eByteOrderLittle, 4, 2, 4, llvm::Triple::arm, ArchSpec::eCore_arm_armv8l,
+     "armv8l"},
     {eByteOrderLittle, 4, 4, 4, llvm::Triple::aarch64_32,
----------------
Is this just clang format being greedy?


================
Comment at: lldb/unittests/ObjectFile/WASM/CMakeLists.txt:11
+  )
+
----------------
trailing newline


================
Comment at: lldb/unittests/ObjectFile/WASM/TestObjectFileWasm.cpp:2
+//===-- TestObjectFileWasm.cpp -----------------------------------*- C++
+//-*-===//
+//
----------------
somethings up with the ling wrapping here.


================
Comment at: llvm/include/llvm/BinaryFormat/ELF.h:314
   EM_BPF = 247,           // Linux kernel bpf virtual machine
+  EM_WASM = 248,          // WebAssembly
 };
----------------
This seems like an odd place to add this, given that are not using or relying on ELF anywhere.  Does this make sense?
