From 89e02311ab02be8dcdf81636875d5d91cc671d10 Mon Sep 17 00:00:00 2001 From: Alexey Samsonov Date: Thu, 4 Sep 2025 13:44:55 -0700 Subject: [PATCH] [libc] Remove unused _Thread_local define from headers. It was added in dd33f9cdef9f6209aa34713e1417f4a2e24e5ca6 to describe thread-local errno, but is no longer used in the codebase (with the exception of a single integration test, but the llvm-libc-provided `#define _Thread_local thread_local` is not needed there anyway, since `_Thread_local` is a keyword from C11 onwards. --- libc/include/__llvm-libc-common.h | 3 --- 1 file changed, 3 deletions(-) diff --git a/libc/include/__llvm-libc-common.h b/libc/include/__llvm-libc-common.h index 1fe3f4d2aea9c..70d8263e63b65 100644 --- a/libc/include/__llvm-libc-common.h +++ b/libc/include/__llvm-libc-common.h @@ -37,9 +37,6 @@ #undef _Alignof #define _Alignof alignof -#undef _Thread_local -#define _Thread_local thread_local - #undef __NOEXCEPT #if __cplusplus >= 201103L #define __NOEXCEPT noexcept
