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. --- ChangeLog | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index a924f87c2d..1101834e04 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,5 +1,11 @@ 2016-05-10 Adhemerval Zanella + [BZ #21428] + * include/unistd.h (read): Add hidden proto. + * io/Makefile (CFLAGS-read.c): New define. + * nptl/Makefile (CFLAGS-read.c): Likewise. + * sysdeps/unix/sysv/linux/read.c: New file. + * io/Makefile (CFLAGS-creat.c): New rule.
