From f6a191a6ee0313d61dffa70d86b033c5a598f907 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Tue, 3 Nov 2015 10:13:18 -0200 Subject: Consolidate Linux read syscall This patch consolidates the read Linux syscall implementation on sysdeps/unix/sysv/linux/read.c. This leads to a different frame pointer creation on some architectures: * It fixes BZ#21428 on aarch64, since now the returned address for the read syscall can be correctly found out by backtrace_symbols. * It makes tst-backtrace{5,6} fails on powerpc due an issue on its custom backtrace implementation. It is fixed on subsequent patch from this set. Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, arch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu. [BZ #21428] * include/unistd.h (read): Add hidden proto. * io/Makefile (CFLAGS-read.c): New rule. * nptl/Makefile (CFLAGS-read.c): New rule. * sysdeps/unix/sysv/linux/read.c: New file. --- io/Makefile | 1 + 1 file changed, 1 insertion(+) (limited to 'io/Makefile') diff --git a/io/Makefile b/io/Makefile index 8b1c250fda..db14c0dd82 100644 --- a/io/Makefile +++ b/io/Makefile @@ -100,6 +100,7 @@ CFLAGS-posix_fallocate64.c = -fexceptions CFLAGS-fallocate.c = -fexceptions CFLAGS-fallocate64.c = -fexceptions CFLAGS-sync_file_range.c = -fexceptions +CFLAGS-read.c = -fexceptions CFLAGS-test-stat.c = -D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE CFLAGS-test-lfs.c = -D_LARGEFILE64_SOURCE -- cgit v1.2.3-70-g09d2
