From ae7249250ea650ec82bc545d4281b852020c7a6f Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Fri, 24 Jan 2014 00:50:06 +0100 Subject: [PATCH 1/1] Implement aarch64 support - IFUNC support is not implemented, the rest works well. The only other failure is in wide char functions, and that occurs on x86_64 as well. --- configure.ac | 3 +- sysdeps/linux-gnu/Makefile.am | 4 +- sysdeps/linux-gnu/aarch64/Makefile.am | 25 + sysdeps/linux-gnu/aarch64/arch.h | 37 ++ sysdeps/linux-gnu/aarch64/fetch.c | 365 +++++++++++ sysdeps/linux-gnu/aarch64/plt.c | 38 ++ sysdeps/linux-gnu/aarch64/ptrace.h | 22 + sysdeps/linux-gnu/aarch64/regs.c | 130 ++++ sysdeps/linux-gnu/aarch64/signalent.h | 52 ++ sysdeps/linux-gnu/aarch64/syscallent.h | 1100 ++++++++++++++++++++++++++++++++ sysdeps/linux-gnu/aarch64/trace.c | 83 +++ 11 files changed, 1857 insertions(+), 2 deletions(-) create mode 100644 sysdeps/linux-gnu/aarch64/Makefile.am create mode 100644 sysdeps/linux-gnu/aarch64/arch.h create mode 100644 sysdeps/linux-gnu/aarch64/fetch.c create mode 100644 sysdeps/linux-gnu/aarch64/plt.c create mode 100644 sysdeps/linux-gnu/aarch64/ptrace.h create mode 100644 sysdeps/linux-gnu/aarch64/regs.c create mode 100644 sysdeps/linux-gnu/aarch64/signalent.h create mode 100644 sysdeps/linux-gnu/aarch64/syscallent.h create mode 100644 sysdeps/linux-gnu/aarch64/trace.c diff --git a/configure.ac b/configure.ac index c6e6bf0..0e9a124 100644 --- a/configure.ac +++ b/configure.ac @@ -1,6 +1,6 @@ # -*- Autoconf -*- # This file is part of ltrace. -# Copyright (C) 2010,2013 Petr Machata, Red Hat Inc. +# Copyright (C) 2010,2012,2013,2014 Petr Machata, Red Hat Inc. # Copyright (C) 2010,2011 Joe Damato # Copyright (C) 2010 Marc Kleine-Budde # Copyright (C) 2010 Zachary T Welch @@ -399,6 +399,7 @@ AC_CONFIG_FILES([ Makefile sysdeps/Makefile sysdeps/linux-gnu/Makefile + sysdeps/linux-gnu/aarch64/Makefile sysdeps/linux-gnu/alpha/Makefile sysdeps/linux-gnu/arm/Makefile sysdeps/linux-gnu/cris/Makefile diff --git a/sysdeps/linux-gnu/Makefile.am b/sysdeps/linux-gnu/Makefile.am index ecee577..ec26162 100644 --- a/sysdeps/linux-gnu/Makefile.am +++ b/sysdeps/linux-gnu/Makefile.am @@ -1,4 +1,5 @@ # This file is part of ltrace. +# Copyright (C) 2014 Petr Machata, Red Hat, Inc. # Copyright (C) 2010,2012 Marc Kleine-Budde, Pengutronix # # This program is free software; you can redistribute it and/or @@ -16,7 +17,8 @@ # Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA # 02110-1301 USA -DIST_SUBDIRS = alpha arm cris ia64 m68k mips ppc s390 sparc x86 +DIST_SUBDIRS = aarch64 alpha arm cris ia64 m68k mips ppc s390 \ + sparc x86 SUBDIRS = \ $(HOST_CPU) diff --git a/sysdeps/linux-gnu/aarch64/Makefile.am b/sysdeps/linux-gnu/aarch64/Makefile.am new file mode 100644 index 0000000..0af4e6e --- /dev/null +++ b/sysdeps/linux-gnu/aarch64/Makefile.am @@ -0,0 +1,25 @@ +# This file is part of ltrace. +# Copyright (C) 2014 Petr Machata, Red Hat, Inc. +# +# This program is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public License as +# published by the Free Software Foundation; either version 2 of the +# License, or (at your option) any later version. +# +# This program 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.
