…lyxyas Fix FP in `threadlocal!` when falling back to `os_local` **Issue**: The lint always triggers for some targets. **Why**: The lint assumes an `__init` function is not present for const initializers. This does not hold for all targets. Some targets always have an initializer function. **Fix**: If an initializer function exists, we check that it is not a `const` fn. Lint overview before the patch: 1. Outside `threadlocal!`, then exit early. 2. In `threadlocal!` and `__init` does not exist => is const already, exit early. 3. In `threadlocal!` and `__init` exists and `__init` body can be `const` => we lint. Lint overview after the patch: 1. Outside `threadlocal!`, then exit early. 2. In `threadlocal!` and `__init` does not exist => is const already, exit early. 3. In `threadlocal!` and `__init` exists and is `const fn` => is const already, exit early. 4. In `threadlocal!` and `__init` exists and is not `const fn` and `__init` body can be `const` => we lint. The patch adds step 3. changelog: Fixed fp in [`thread_local_initializer_can_be_made_const`] where fallback implementation of `threadlocal!` was always linted. ## Verifying the changes For each of these platforms [ mac, x86_64-windows-gnu, x86_64-windows-msvc ]: 1. switched to master, ran bless. Found a failure for windows-gnu. 2. switched to patch, ran bless. Success for all three platforms. ## How platform affects the lint: The compiler performs a [conditional compilation depending on platform features](https://doc.rust-lang.org/src/std/sys/common/thread_local/mod.rs.html). The `os_local` fallback includes a call to `__init`, without step 3, we lint in all cases. ```rust cfg_if::cfg_if! { if #[cfg(any(all(target_family = "wasm", not(target_feature = "atomics")), target_os = "uefi"))] { #[doc(hidden)] mod static_local; #[doc(hidden)] pub use static_local::{Key, thread_local_inner}; } else if #[cfg(target_thread_local)] { #[doc(hidden)] mod fast_local; #[doc(hidden)] pub use fast_local::{Key, thread_local_inner}; } else { #[doc(hidden)] mod os_local; #[doc(hidden)] pub use os_local::{Key, thread_local_inner}; } } ``` r? `@llogiq`
