From 175cef4163dd60f95106cfd5f593b8a4e09d02c9 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Tue, 20 May 2014 21:27:13 +0000 Subject: Fix ARM build with GCC trunk. sysdeps/unix/sysv/linux/arm/unwind-resume.c and sysdeps/unix/sysv/linux/arm/unwind-forcedunwind.c have static variables that are written in C code but only read from toplevel asms. Current GCC trunk now optimizes away such apparently write-only static variables, so causing a build failure. This patch marks those variables with __attribute_used__ to avoid that optimization. Tested that this fixes the build for ARM. * sysdeps/unix/sysv/linux/arm/unwind-forcedunwind.c (libgcc_s_resume): Use __attribute_used__. * sysdeps/unix/sysv/linux/arm/unwind-resume.c (libgcc_s_resume): Likewise. --- ChangeLog | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index 390f181..7f49fbb 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,10 @@ +2014-05-20 Joseph Myers + + * sysdeps/unix/sysv/linux/arm/unwind-forcedunwind.c + (libgcc_s_resume): Use __attribute_used__. + * sysdeps/unix/sysv/linux/arm/unwind-resume.c (libgcc_s_resume): + Likewise. + 2014-05-20 Adhemerval Zanella * sysdeps/powerpc/fpu/math_private.h [__copysignf]: Fix copysign macro -- cgit v1.1
