Implement #[alloc_error_handler] This to-be-stable attribute is equivalent to `#[lang = "oom"]`. It is required when using the alloc crate without the std crate. It is called by `handle_alloc_error`, which is in turned called by "infallible" allocations APIs such as `Vec::push`. 2018-07-06 08:49:52 -05:00			`// compile-flags:-C panic=abort`

Rewrite implementation of `#[alloc_error_handler]` The new implementation doesn't use weak lang items and instead changes `#[alloc_error_handler]` to an attribute macro just like `#[global_allocator]`. The attribute will generate the `__rg_oom` function which is called by the compiler-generated `__rust_alloc_error_handler`. If no `__rg_oom` function is defined in any crate then the compiler shim will call `__rdl_oom` in the alloc crate which will simply panic. This also fixes link errors with `-C link-dead-code` with `default_alloc_error_handler`: `__rg_oom` was previously defined in the alloc crate and would attempt to reference the `oom` lang item, even if it didn't exist. This worked as long as `__rg_oom` was excluded from linking since it was not called. This is a prerequisite for the stabilization of `default_alloc_error_handler` (#102318). 2022-10-13 20:24:58 -05:00			`info: Layout, //~^ ERROR mismatched types`
