Export kernel descriptor for amdgpu kernels The host runtime (HIP or HSA) expects a kernel descriptor object for each kernel in the ELF file. The amdgpu LLVM backend generates the object. It is created as a symbol with the name of the kernel plus a `.kd` suffix. Add it to the exported symbols in the linker script, so that it can be found. 2025-02-10 22:37:43 +01:00			`#![allow(internal_features)]`

tests: `{Meta,Pointee}Sized` in non-minicore tests As before, add `MetaSized` and `PointeeSized` traits to all of the non-minicore `no_core` tests so that they don't fail for lack of language items. 2025-01-23 11:25:12 +00:00			`#[lang = "pointee_sized"]`
