<pre>I'm pretty sure this worked in LLVM 11, and doesn't work in LLVM 12.0.0-rc4.
Steps to reproduce:
1. get cbindgen-0.19.0
2. RUSTFLAGS='-C linker=clang -C linker-plugin-lto -C link-arg=-fuse-ld=lld'
cargo build --release
Expected results:
It builds.
Actual results:
Wrong types for attribute: inalloca nest noalias nocapture noundef nonnull
readnone readonly signext zeroext byref(void) byval(void) preallocated(void)
sret(void) align 1 dereferenceable(1) dereferenceable_or_null(1)
tail call fastcc align 8 void
