Package: libgc Version: 1:7.1-3 Severity: serious Hi,
Starting with version 7.x, libgc now contains a convenience copy of libatomic-ops in the source. This might be necessary, because it seems to need the file atomic_ops.c to be present to build. The problem is that Debian's libatomic-ops contains patches to support more architectures that aren't in the convenience copy in libgc. This is serious because it's a blocker for 542285 until the patches from Debian's version are cherry-picked, or until the convenience copy is ripped out in some way. This is problematic because it's led to duplicated work, since the version of libatomic-ops in Debian has extra patches from the upstream cvs, and the version embedded in libgc has been modified as well. Observe the differences in the contents of libatomic_ops/src/atomic_ops/sysdeps/gcc. Debian's libatomic-ops after the patches have been applied: alpha.h* arm.h* cris.h* hppa.h* ia64.h* m68k.h* mips.h* powerpc.h* s390.h* sh.h* sparc.h* x86_64.h* x86.h* Debian's libgc: alpha.h avr32.h ia64.h powerpc.h sparc.h x86.h arm.h cris.h hppa.h m68k.h s390.h x86_64.h Notice that the libgc convenience copy has avr32 support due to: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=528406 But the libatomic-ops in Debian has sh and mips support due to the work in: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=336112 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=547136 These should be synced in some way. Incidentally if you want to test on mips you can use a qemu image from: http://www.aurel32.net/info/debian_mips_qemu.php I hope this is some help.
