Don't force-enable frame pointers when generating debug info We apparently used to generate bad/incomplete debug info causing debuggers not to find symbols of stack allocated variables. This was somehow worked around by having frame pointers. With the current codegen, this seems no longer necessary, so we can remove the code that force-enables frame pointers whenever debug info is requested. Since certain situations, like profiling code profit from having frame pointers, we add a -Cforce-frame-pointers flag to always enable frame pointers. Fixes #11906 2018-01-03 09:29:27 +00:00
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`. 2024-05-29 04:11:20 +00:00			`#![crate_type = "lib"]`

Use function attribute "frame-pointer" instead of "no-frame-pointer-elim" LLVM 8 (D56351) introduced "frame-pointer". In LLVM 10 (D71863), "no-frame-pointer-elim"/"no-frame-pointer-elim-non-leaf" will be ignored. 2019-12-31 05:35:13 +00:00			`// CHECK: attributes #{{.*}} "frame-pointer"="all"`
