From fb37ef69602a1ba635268cd9033a86adc817c53d Mon Sep 17 00:00:00 2001 From: Szabolcs Nagy Date: Thu, 18 Feb 2021 10:56:34 +0000 Subject: aarch64: Remove the unused __read_tp symbol This was likely a mistake in the original aarch64 port copied over from arm: on aarch64 tpidr_el0 register is always available. The __read_tp symbol is visible with static linking, but it's not part of the public ABI so it should be safe to remove. --- sysdeps/unix/sysv/linux/aarch64/Makefile | 7 ------- sysdeps/unix/sysv/linux/aarch64/__read_tp.S | 25 ------------------------ sysdeps/unix/sysv/linux/aarch64/libc-__read_tp.S | 19 ------------------ 3 files changed, 51 deletions(-) delete mode 100644 sysdeps/unix/sysv/linux/aarch64/__read_tp.S delete mode 100644 sysdeps/unix/sysv/linux/aarch64/libc-__read_tp.S (limited to 'sysdeps') diff --git a/sysdeps/unix/sysv/linux/aarch64/Makefile b/sysdeps/unix/sysv/linux/aarch64/Makefile index 4bcae85bca..3f22f71bef 100644 --- a/sysdeps/unix/sysv/linux/aarch64/Makefile +++ b/sysdeps/unix/sysv/linux/aarch64/Makefile @@ -1,11 +1,4 @@ -ifeq ($(subdir),csu) -sysdep_routines += __read_tp libc-__read_tp -static-only-routines += __read_tp -shared-only-routines += libc-__read_tp -endif - ifeq ($(subdir),elf) -sysdep-rtld-routines += __read_tp ifeq ($(build-shared),yes) # This is needed for DSO loading from static binaries. sysdep-dl-routines += dl-static diff --git a/sysdeps/unix/sysv/linux/aarch64/__read_tp.S b/sysdeps/unix/sysv/linux/aarch64/__read_tp.S deleted file mode 100644 index 3a18d73399..0000000000 --- a/sysdeps/unix/sysv/linux/aarch64/__read_tp.S +++ /dev/null @@ -1,25 +0,0 @@ -/* Copyright (C) 2005-2021 Free Software Foundation, Inc. - - This file is part of the GNU C Library. - - The GNU C Library is free software; you can redistribute it and/or - modify it under the terms of the GNU Lesser General Public License as - published by the Free Software Foundation; either version 2.1 of the - License, or (at your option) any later version. - - The GNU C Library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
