 +
 +  [changes brought forward from 1:3.8-2+rpi1 by Peter Michael Green <plugwash@raspbian.org> at Sat, 14 May 2016 21:43:35 +0000]
 +  * Pass armv6-* as triplet rather than arm-* to hopefully stop llvm toolchain 
 +    assuming armv7. (didn't work, it appears that Debian isn't currently using
 +    the autoconf based build).
 +  * Cleanup .pyc files in clean target.
 +  * Add a hack to the cmake based build to force armv6 (unfortunately the cmake
 +    based build relies on config.guess which assumes you want to build for the
 +    hardware you are running on).
 +  * Remove -march=armv7-a in compiler-rt/cmake/config-ix.cmake
 +  * Add -DCOMPILER_RT_BUILD_BUILTINS=OFF to disable parts of compiler-rt that
 +    are broken on lower arm architectures.
 +  [changes introduced in 1:3.8.1-12+rpi1 by Peter Michael Green]
 +  * Disable testsuite, it seems to be crashing buildboxes.
 +
 +  [changes brought forward from 1:3.8.1-12+rpi2 by Peter Michael Green <plugwash@raspbian.org> at Mon, 03 Oct 2016 22:58:38 +0000]
 +  * Really disable testsuite.
 +
 +  [changes introduced in 1:3.8.1-17+rpi1 by Peter Michael Green]
 +  * Remove more crap in clean target.
 +  * Force creation of debian/man.
 +  * Set config.guess.hack back to mode 644 in clean target to keep dgit happy.

+   * Really fix the latomic link on armel (called armv7l on cmake)
+     So, using arm.* to link against latomic

+ llvm-toolchain-3.8 (1:3.8.1-25) unstable; urgency=medium
+ 
+   * Fix the detection of gcc (Closes: #853523)
+   * Force the deactivation of ocaml until the transition is done
+   * Standards-Version: 4.1.0
+   * Backport the gsplit dwarf fix (Closes: #853523)
+   * Try to fix the mipsel FTBFS (Closes: #877567)
+     I am trying the first option from the bug:
+     - gsplit-dward on 32 bits archs
+     - -g everywhere
+     Many thanks to Adrian Bunk for that
+   * clang was producing unusable binaries on armv5tel (Closes: #868779)
+     Thanks to Adrian Bunk for the patch
+   * Backport the patch for bind (ftfbs-gcc.diff)
+ 
+   [ Gianfranco Costamagna, John Paul Adrian Glaubitz ]
+   * Add powerpcspe to latomic archs
+ 
+   [ Gianfranco Costamagna ]
+   * use -g1 where Debug symbols have a 1GB size
