[DirectX] Updating DXContainer logic to read version 1.2 of static samplers (#160184)

2025-09-26T17:07:45+00:00

This PR is updating `Object/DXContainer.h` so that we can read data from
root signature version 1.2, which adds flags into static samplers.

[DirectX] Add ObjectFile boilerplate for objdump (#151434)

2025-08-04T15:57:25+00:00

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.

Fixes #151433

[llvm] Remove unused includes (NFC) (#148768)

2025-07-15T05:19:14+00:00

These are identified by misc-include-cleaner.  I've filtered out those
that break builds.  Also, I'm staying away from llvm-config.h,
config.h, and Compiler.h, which likely cause platform- or
compiler-specific build failures.

Add support for PSV EntryFunctionName (#86296)

2024-03-25T17:18:53+00:00

This change introduces a version 3 of the PSV data that includes support
for the name of the entry function as an offset into StringTable data to
a null-terminated utf-8 string.

Additional tests were added to ensure that the new value was properly
serialized/deserialized from object data.

Fixes #80175
