From 90e97b37201c9b33ee79296b6eb034d5d5db925c Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Wed, 21 Apr 2021 19:49:51 +0200 Subject: [PATCH] Remove pthread_key_create-related internals from libc-lock.h And libc-lockP.h. This is no longer used because all internal TLS use goes directly to the thread descriptor/TCB or uses ELF TLS. --- sysdeps/generic/libc-lock.h | 12 ------------ sysdeps/htl/libc-lockP.h | 13 ------------- sysdeps/nptl/libc-lockP.h | 30 +++++++----------------------- 3 files changed, 7 insertions(+), 48 deletions(-) diff --git a/sysdeps/generic/libc-lock.h b/sysdeps/generic/libc-lock.h index 6b1e98e..c538e85 100644 --- a/sysdeps/generic/libc-lock.h +++ b/sysdeps/generic/libc-lock.h @@ -125,16 +125,4 @@ /* We need portable names for some of the functions. */ #define __libc_mutex_unlock -/* Type for key of thread specific data. */ -typedef int __libc_key_t; - -/* Create key for thread specific data. */ -#define __libc_key_create(KEY,DEST) ((void) (KEY), (void) (DEST), -1) - -/* Set thread-specific data associated with KEY to VAL. */ -#define __libc_setspecific(KEY,VAL) ((void) (KEY), (void) (VAL)) - -/* Get thread-specific data associated with KEY. */ -#define __libc_getspecific(KEY) ((void) (KEY), (void *) 0) - #endif /* libc-lock.h */ diff --git a/sysdeps/htl/libc-lockP.h b/sysdeps/htl/libc-lockP.h index f183bde..eb09171 100644 --- a/sysdeps/htl/libc-lockP.h +++ b/sysdeps/htl/libc-lockP.h @@ -22,9 +22,6 @@ #include #include -/* Type for key to thread-specific data. */ -typedef pthread_key_t __libc_key_t; - /* If we check for a weakly referenced symbol and then perform a normal jump to it te code generated for some platforms in case of PIC is unnecessarily slow.
