-#### Conditional assembly tests based on instruction support
-
-Tests that depend on specific assembly instructions being available can use the
-`//@ needs-asm-mnemonic: <MNEMONIC>` directive.
-This will skip the test if the target backend does not support the specified instruction mnemonic.
-
-For example, a test that requires the `RET` instruction:
-```rust,ignore
-//@ needs-asm-mnemonic: RET
-```

   For tests that cross-compile to explicit targets
   via `--target`, use `needs-llvm-components` instead to ensure the appropriate

-- `needs-asm-mnemonic: <MNEMONIC>` — ignores if the target backend does not
-  support the specified assembly mnemonic (e.g., `RET`, `NOP`).
-  Only supported with the LLVM backend.
+- `needs-asm-ret` - ignores if the target does not have a `ret` instruction
+  in its assembly syntax. Most target architectures have this instruction,
+  making it handy for portable inline-assembly tests, but some architectures
+  (e.g. 32-bit ARM) do not have it.
 - `needs-profiler-runtime` — ignores the test if the profiler runtime was not
   enabled for the target (`build.profiler = true` in `bootstrap.toml`)
