Pass tune-cpu to LLVM I think this is how it should work... 2020-09-17 04:39:26 -05:00			`// This test makes sure that functions get annotated with the proper`

Remove redundant `ignore-tidy-linelength` annotations This is step 2 towards fixing #77548. In the codegen and codegen-units test suites, the `//` comment markers were kept in order not to affect any source locations. This is because these tests cannot be automatically `--bless`ed. 2021-04-03 06:05:11 -05:00			`//`
Automatically enable cross-crate inlining for small functions 2023-10-06 19:29:42 -05:00			`//@ compile-flags: -C no-prepopulate-passes -C panic=abort -C linker-plugin-lto -Cpasses=name-anon-globals -Z tune-cpu=generic -Copt-level=0`

Run rustfmt on `tests/codegen/`. Except for `simd-intrinsic/`, which has a lot of files containing multiple types like `u8x64` which really are better when hand-formatted. There is a surprising amount of two-space indenting in this directory. Non-trivial changes: - `rustfmt::skip` needed in `debug-column.rs` to preserve meaning of the test. - `rustfmt::skip` used in a few places where hand-formatting read more nicely: `enum/enum-match.rs` - Line number adjustments needed for the expected output of `debug-column.rs` and `coroutine-debug.rs`. 2024-05-28 23:11:20 -05:00			`pub extern "C" fn exported() {`
