…plied at the crate level. When `no_builtins` is applied at the crate level, we should add the `no-builtins` attribute to each function to ensure it takes effect in LTO.

…, r=pnkfelix Add the `no-builtins` attribute to functions when `no_builtins` is applied at the crate level. **When `no_builtins` is applied at the crate level, we should add the `no-builtins` attribute to each function to ensure it takes effect in LTO.** This is also the reason why no_builtins does not take effect in LTO as mentioned in rust-lang#35540. Now, `#![no_builtins]` should be similar to `-fno-builtin` in clang/gcc, see https://clang.godbolt.org/z/z4j6Wsod5. Next, we should make `#![no_builtins]` participate in LTO again. That makes sense, as LTO also takes into consideration function-level instruction optimizations, such as the MachineOutliner. More importantly, when a user writes a large `#![no_builtins]` crate, they would like this crate to participate in LTO as well. We should also add a function-level no_builtins attribute to allow users to have more control over it. This is similar to Clang's `__attribute__((no_builtin))` feature, see https://clang.godbolt.org/z/Wod6KK6eq. Before implementing this feature, maybe we should discuss whether to support more fine-grained control, such as `__attribute__((no_builtin("memcpy")))`. Related discussions: - rust-lang#109821 - rust-lang#35540 Next (a separate pull request?): - [ ] Revert rust-lang#35637 - [ ] Add a function-level `no_builtin` attribute?

Make it clearer that edition functions are `>=`, not `==` r? `@Nilstrieb` We could also perhaps derive `Ord` on `Edition` and use comparison operators.
… r=eholk Improve error message when closing bracket interpreted as formatting fill character Fixes rust-lang#112732 by explaining why it's erroring in the way it is.
…-105735-fix, r=notriddle,aDotInTheVoid Fix invalid display of inlined re-export when both local and foreign items are inlined Fixes rust-lang#105735. The bug is actually quite interesting: at the `clean` pass, local inlined items have their `use` item removed, however foreign items don't have their `use` item removed because it's in the `clean` pass that we handle them. So when a `use` inlines both a local and a foreign item, it will work as expected for the foreign one, but not for the local as its `use` should not be around anymore. To prevent this, I created a new `inlined_foreigns` field into the `Module` struct to allow to remove the `use` item early on for foreign items as well. Then we iterate it in the `clean` pass directly. r? ``@notriddle``

Fix inline_const with interpolated block
Interpolation already worked when we had a `const $block` that wasn't a statement expr:
```
fn foo() {
let _ = const $block;
}
```
But it was failing when the const block was in statement expr position:
```
fn foo() {
const $block;
}
```
... because of a bug in a check for const items. This fixes that.

cc rust-lang#112953 (comment), though I don't think this requires an FCP since it's already supported in exprs and seems to me to be fully a parser bug.
