[DirectX] Add split-section to llvm-objcopy and implement it for DXContainer
#153265

@llvm/pr-subscribers-llvm-binary-utilities @llvm/pr-subscribers-backend-directx Author: Finn Plummer (inbelic) ChangesThis pr adds the This difference in behaviour is used for DXC compatibility with This pr then implements this functionality for This is the second step of #150277 to implement as a compiler action that invokes llvm-objcopy for functionality. This also completes the implementation of Patch is 27.10 KiB, truncated to 20.00 KiB below, full version: https://github.com/llvm/llvm-project/pull/153265.diff 8 Files Affected:

I've not got time to review this code today, but one query I have is: what's the difference between this option and the behaviour of |
|
@inbelic can confirm, but I thought the intent was for this to work like We have a few common tooling cases for DX files where the compiler generates an object with a bunch of sections that you may strip out later (debug info, runtime reflection, runtime signatures). What we'd like to have is a tooling path where we can do that with a single invocation of objcopy something like: I suggested making this a general option since it could be implemented for any object file type, but if you think it is better to do it as a DX-specific option we could do that as well. |

There was a problem hiding this comment.
Perhaps there is a better way to do this check? Would appreciate suggestions.
I tried to instantiate a NameMatcher here but it is a bit awkward. I also considered adding the section names directly to ToRemove in ObjcopyOptions.cpp but I thought that would be rather confusing.
Rather than a new option, I'd rather you just add support for |
I assume you mean It could be that such an option isn't really applicable to other object formats, and we could go about this as a We thought it best not to have a different implementation of |
The concern that I have with this is that if we want to take an input file that has 8 sections, pull 3 out into their own files and leave the remaining 5, can we do that without invoking My reading of the current options is that to do what I described above we would need to invoke objcopy multiple times like: It does seem like we should support the |
This pr adds the
split-sectionoption tollvm-objcopyas a common option. It differs fromdump-sectionas it will produce a standalone object with just one section, as opposed to just the section contents.This difference in behaviour is used for DXC compatibility with
extract-rootsignatureand/Frs.This pr then implements this functionality for
DXContainerobjects.This is the second step of #150277 to implement as a compiler action that invokes llvm-objcopy for functionality.
This also completes the implementation of
extract-rootsignatureas described in #149560.
