From 43a336e63f16c639e0e6fefdd7404509159c07b1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ignacy=20Gaw=C4=99dzki?= Date: Thu, 6 Oct 2016 20:15:58 +0200 Subject: libpthread: Fix inclusion of unwind code. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since librt and libpthread are now integrated into libc, including unwind-resume and unwind-forcedunwind implementations of unwind code makes no sense. Only unwind-forcedunwind is now included with functions hidden to avoid them overriding the ones from libgcc_s. * libpthread/nptl/sysdeps/generic/unwind-resume.h: New. Define generic PERSONALITY_PROTO and PERSONALITY_ARGS and set HAVE_ARCH_UNWIND_RESUME to 0. * libpthread/nptl/sysdeps/pthread/unwind-resume.c: Move... * libpthread/nptl/sysdeps/generic/unwind-resume.c: ... here. Include generic implementation of _Unwind_Resume on the condition that !HAVE_ARCH_UNWIND_RESUME. Make functions hidden to prevent them from overriding libgcc_s's ones. * libpthread/nptl/sysdeps/pthread/unwind-forcedunwind.c: Likewise. * libpthread/nptl/sysdeps/arm/unwind-resume.h: New. Define ARM-specific PERSONALITY_PROTO and PERSONALITY_ARGS and set HAVE_ARCH_UNWIND_RESUME to 1. * libpthread/nptl/sysdeps/arm/arm-unwind-resume.c, * libpthread/nptl/sysdeps/arm/pt-arm-unwind-resume.c, * libpthread/nptl/sysdeps/arm/rt-arm-unwind-resume.c: New. ARM-specific implementations of _Unwind_Resume resp. for libc, libpthread and librt. * libpthread/nptl/sysdeps/Makefile.commonarch: Remove both arm-unwind-resume and rt-arm-unwind-resume from libpthread_arch_CSRC. * libpthread/nptl/sysdeps/unix/sysv/linux/arm/unwind-forcedunwind.c, * libpthread/nptl/sysdeps/unix/sysv/linux/arm/unwind-resume.c: Remove.
