From 2fe96439fb81d85ea78a6311b1d9e6ed9b85bcfa Mon Sep 17 00:00:00 2001 From: Chris B Date: Mon, 4 Aug 2025 10:57:25 -0500 Subject: [PATCH] [DirectX] Add ObjectFile boilerplate for objdump (#151434) This change adds boilerplate code to implement the object::ObjectFile interface for the DXContainer object file and an empty implementation of the objdump Dumper object. Adding an ObjectFile implementation for DXContainer is a bit odd because the DXContainer format doesn't have a symbol table, so there isn't a reasonable implementation for the SymbolicFile interfaces. That said, it does have sections, and it will be useful for objdump to be able to inspect some of the structured data stored in some of the special named sections. At this point in the implementation it can't do much other than dump the part names, offsets, and sizes. Dumping detailed structured section contents to be extended in subsequent PRs.
