error: could not compile `std` (lib) due to 1 previous error
"\\\\?\\C:\\Users\\anakh\\.rustup\\toolchains\\nightly-2024-06-26-x86_64-pc-windows-msvc\\bin\\cargo.exe" "build" "--manifest-path" "C:\\Users\\anakh\\dev\\rustc_codegen_cranelift\\.\\build\\stdlib\\library/sysroot\\Cargo.toml" "--target-dir" "C:\\Users\\anakh\\dev\\rustc_codegen_cranelift\\.\\build\\stdlib_target" "--locked" "--target" "x86_64-pc-windows-msvc" "--release" "--features" "backtrace panic-unwind" exited with status ExitStatus(ExitStatus(101))
error: process didn't exit successfully: `C:/Users/anakh/dev/.cargo-target\debug\y.exe build` (exit code: 1)

However, I had this in my global .cargo/config.toml:

[target.x86_64-pc-windows-msvc]
linker = "rust-lld.exe"

However, commenting out the rust-lld line so that it defaults to the default linker, I was able to build rustc_codegen_cranelift successfully.

Just wondering if this is an issue with the build for rustc_codegen_cranelift, or rust-lld, or MSVC, or my particular setup, or...

Also of note, the error seems almost identical to the one encountered in this issue (though usage is completely different)

Research direction

Reproduce the Windows failure with .\y.ps1 prepare followed by .\y.ps1 build, using the reported rustc, MSVC, and rust-lld setup. Trace the compiler_builtins memory-symbol references during the stdlib build and determine why linking fails; done means rustc_codegen_cranelift builds successfully on this Windows configuration.
