From 1ae4a0cc3487f28b29f36afe8056535afad21e7b Mon Sep 17 00:00:00 2001 From: Josh Triplett Date: Sun, 10 Aug 2025 14:25:43 -0700 Subject: library: Migrate from `cfg_if` to `cfg_select` Migrate the standard library from using the external `cfg_if` crate to using the now-built-in `cfg_select` macro. This does not yet eliminate the dependency from `library/std/Cargo.toml`, because while the standard library itself no longer uses `cfg_if`, it also incorporates the `backtrace` crate, which does. Migration assisted by the following vim command (after selecting the full `cfg_if!` invocation): ``` '<,'>s/\(cfg_if::\)\?cfg_if/cfg_select/ | '<,'>s/^\( *\)} else {/\1}\r\1_ => {/c | '<,'>s/^\( *\)} else if #\[cfg(\(.*\))\] /\1}\r\1\2 => /e | '<,'>s/if #\[cfg(\(.*\))\] {/\1 => {/e ``` This is imperfect, but substantially accelerated the process. This prompts for confirmation on the `} else {` since that can also appear inside one of the arms. This also requires manual intervention to handle any multi-line conditions. --- library/std/src/sync/reentrant_lock.rs | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) (limited to 'library/std/src/sync') diff --git a/library/std/src/sync/reentrant_lock.rs b/library/std/src/sync/reentrant_lock.rs index 727252f03a2..4140718560c 100644 --- a/library/std/src/sync/reentrant_lock.rs +++ b/library/std/src/sync/reentrant_lock.rs @@ -1,5 +1,3 @@ -use cfg_if::cfg_if; - use crate::cell::UnsafeCell; use crate::fmt; use crate::ops::Deref; @@ -87,8 +85,8 @@ pub struct ReentrantLock { data: T, } -cfg_if!( - if #[cfg(target_has_atomic = "64")] { +cfg_select!( + target_has_atomic = "64" => { use crate::sync::atomic::{Atomic, AtomicU64, Ordering::Relaxed}; struct Tid(Atomic); @@ -110,7 +108,8 @@ cfg_if!( self.0.store(value, Relaxed); } } - } else { + } + _ => { /// Returns the address of a TLS variable.
