[PATCH] D126812: [Binary] Promote OffloadBinary to inherit from Binary

[Artem Belevich via Phabricator via cfe-commits]

tra added a comment.

LGTM in principle, with new nits.



================
Comment at: llvm/include/llvm/Object/OffloadBinary.h:121
                 const Entry *TheEntry)
-      : Buffer(Buffer), TheHeader(TheHeader), TheEntry(TheEntry) {
-
+      : Binary(Binary::ID_Offload, Source), Buffer(Source.getBufferStart()),
+        TheHeader(TheHeader), TheEntry(TheEntry) {
----------------
We're losing information by passing only the start of the buffer.
I'd change the type of `Buffer` field to `MemoryBufferRef` instead.


================
Comment at: llvm/lib/Object/OffloadBinary.cpp:18
 using namespace llvm;
-
-namespace llvm {
+using namespace object;
 
----------------
Nit: `using namespace` seems a bit too heavy-handed when you only need one enum
`using object_error = llvm::object::object_error;` would probably do.
TBH, the use of fully qualified enum in only two instances also looked OK to me.

Nit: Offload binary is declared within `llvm` namespace. Removing namespace here and relying on `using namespace llvm;` works, but makes things a bit less obvious. I'd keep the namespace around. Maybe, even remove `using namespace llvm` above, too as it should not be needed if the code is within the actual namespace.
