Inline assembly (`asm!`) is not supported on this target.
Example of erroneous code:
```ignore (cannot-change-target)
// compile-flags: --target sparc64-unknown-linux-gnu
#![no_std]
use core::arch::asm;
fn main() {
unsafe {
asm!(""); // error: inline assembly is not supported on this target
}
}
```
The Rust compiler does not support inline assembly, with the `asm!` macro
(previously `llvm_asm!`), for all targets. All Tier 1 targets do support this
macro but support among Tier 2 and 3 targets is not guaranteed (even when they
have `std` support). Note that this error is related to
`error[E0658]: inline assembly is not stable yet on this architecture`, but
distinct in that with `E0472` support is not planned or in progress.
There is no way to easily fix this issue, however:
* Consider if you really need inline assembly, is there some other way to
achieve your goal (intrinsics, etc)?
* Consider writing your assembly externally, linking with it and calling it
from Rust.
* Consider contributing to <https://github.com/rust-lang/rust> and help
integrate support for your target!
