| #### Note: this error code is no longer emitted by the compiler |
| The `instruction_set` attribute was malformed. |
| |
| Erroneous code example: |
| |
| ```compile_fail |
| #![feature(isa_attribute)] |
| |
| #[instruction_set()] // error: expected one argument |
| pub fn something() {} |
| fn main() {} |
| ``` |
| |
| The parenthesized `instruction_set` attribute requires the parameter to be |
| specified: |
| |
| ``` |
| #![feature(isa_attribute)] |
| |
| #[cfg_attr(target_arch="arm", instruction_set(arm::a32))] |
| fn something() {} |
| ``` |
| |
| or: |
| |
| ``` |
| #![feature(isa_attribute)] |
| |
| #[cfg_attr(target_arch="arm", instruction_set(arm::t32))] |
| fn something() {} |
| ``` |
