| # Codegen backend testing | |
| See also the [Code generation](../../backend/codegen.md) chapter. | |
| In addition to the primary LLVM codegen backend, the rust-lang/rust CI also runs tests of the [cranelift][cg_clif] and [GCC][cg_gcc] codegen backends in certain test jobs. | |
| For more details on the tests involved, see: | |

| - [GCC codegen backend tests](./cg_gcc.md) | |
