Windows `rust-lld` does not support the MSVC `manifestdependency` `.drectve`

[ChrisDenton]

Minimal reproduction (Windows only):

#[link_section = ".drectve"]
#[used]
static DIRECTIVE: [u8; 164] = *br#""/manifestdependency:type='Win32' name='Test.Research.SampleAssembly' version='6.0.0.0' processorArchitecture='X86' publicKeyToken='0000000000000000' language='*'" "#;

fn main() {}

Using the default MSVC linker works:

rustc main.rs

However when using rust-lld.exe it fails:

rustc -C linker="rust-lld.exe" main.rs

The error says it's unsupported:

note: rust-lld: error: /manifestdependency: is not allowed in .drectve

I tried to fix this in llvm/llvm-project@400a1de . It might work now (well, at llvm HEAD. It'll be in LLVM 14. If it's important, we can try to merge it to the LLVM 13 branch.)

Rust recently upgraded to LLVM 14 so I'm closing this as resolved. I'll also comment on the tracking issue.
