C:\py\j\hello_rust>rustc -Vv
rustc 1.46.0 (04488afe3 2020-08-24)
binary: rustc
commit-hash: 04488afe34512aa4c33566eb16d8c912a3ae04f9
commit-date: 2020-08-24
host: i686-pc-windows-gnu
release: 1.46.0
LLVM version: 10.0

I ran this command in order to use the included rust-lld linker:
C:\py\j\hello_rust>set CARGO_TARGET_I686_PC_WINDOWS_GNU_LINKER=rust-lld

Then, I tried to build my Cargo hello world project and here are the results:

C:\py\j\hello_rust>cargo build
   Compiling hello_rust v0.1.0 (C:\py\j\hello_rust)
error: linking with `rust-lld` failed: exit code: 1

error: aborting due to previous error

error: could not compile `hello_rust`.

To learn more, run the command again with --verbose.

I think that this probjem would go away if I used Clang.exe as the linker, but installing clang would be problematic on my end

OK, it seems that you need to pass "-m i386pe" to the linker.
Not "-m=i386pe" or "-mi386pe", it has to be "-m i386pe"
Now I'm getting errors like this, I think it's because kernel32 isn't being linked to

          lld-link: error: too many errors emitted, stopping now (use /errorlimi
t:0 to see all errors)


error: aborting due to previous error

error: could not compile `hello_rust`.

To learn more, run the command again with --verbose.

The only way to fix all this would seemingly be to ship the entire MINGW tool chain along with rust.

Limited support for rust-lld has recently landed in nightly: #75483

I'll look into it tomorrow, this unformatted log is unreadable on the mobile.
