+# `abi_efiapi`
+
+The tracking issue for this feature is: [#65815]
+
+[#65815]: https://github.com/rust-lang/rust/issues/65815
+
+------------------------
+
+The `efiapi` calling convention can be used for defining a function with
+an ABI compatible with the UEFI Interfaces as defined in the [UEFI
+Specification].
+
+Example:
+
+```rust,ignore (not-all-targets-support-uefi)
+#![feature(abi_efiapi)]
+
+extern "efiapi" { fn f1(); }
+
+extern "efiapi" fn f2() { todo!() }
+```

-# `native_link_modifiers_verbatim`
-
-The tracking issue for this feature is: [#81490]
-
-[#81490]: https://github.com/rust-lang/rust/issues/81490
-
-------------------------
-
-The `native_link_modifiers_verbatim` feature allows you to use the `verbatim` modifier.
-
-`+verbatim` means that rustc itself won't add any target-specified library prefixes or suffixes (like `lib` or `.a`) to the library name, and will try its best to ask for the same thing from the linker.
-
-For `ld`-like linkers rustc will use the `-l:filename` syntax (note the colon) when passing the library, so the linker won't add any prefixes or suffixes as well.
-See [`-l namespec`](https://sourceware.org/binutils/docs/ld/Options.html) in ld documentation for more details.
-For linkers not supporting any verbatim modifiers (e.g. `link.exe` or `ld64`) the library name will be passed as is.
-
-The default for this modifier is `-verbatim`.
-
-This RFC changes the behavior of `raw-dylib` linking kind specified by [RFC 2627](https://github.com/rust-lang/rfcs/pull/2627). The `.dll` suffix (or other target-specified suffixes for other targets) is now added automatically.
-If your DLL doesn't have the `.dll` suffix, it can be specified with `+verbatim`.
