Handle asm const similar to inline const Previously, asm consts are handled similar to anon consts rather than inline consts. Anon consts are not good at dealing with lifetimes, because `type_of` has lifetimes erased already. Inline consts can deal with lifetimes because they live in an outer typeck context. And since `global_asm!` lacks an outer typeck context, we have implemented asm consts with anon consts while they're in fact more similar to inline consts. This was changed in #137180, and this means that handling asm consts as inline consts are possible. While as `@compiler-errors` pointed out, `const` currently can't be used with any types with lifetime, this is about to change if #128464 is implemented. This PR is a preparatory PR for that feature. As an unintentional side effect, fix #117877. cc `@Amanieu` r? `@compiler-errors` |
