[Openmp-dev] git diff of clang-omp

[Jack Howarth]

   I know this is somewhat off-topic for this mailing list but it does
relate to the use of openmp and the clang-omp github doesn't have an
associated mailing list. I have been trying to generate a diff of what
changes residing in clang-omp (based on 3.4) still have to be merged into
clang svn. To do this, I started with…

%  git clone -b release_34 https://github.com/llvm-mirror/clang.git
%  cd clang
%  git checkout a335ba031b18e2736120b5b82bfee08c50ec522c

to checkout the release_34 branch and roll it back to the 3.4 release
(which is what clang-omp is supposed to be based on).
     I then though I should be able to generate a git diff with…

%  git remote add -f b https://github.com/clang-omp/clang.git
%  git diff master remotes/b/master

but this seems to be ignoring the roll-back of the the clang release_34
branch. Do I need to do something for the last two commands in order to
ensure that the git diff is against the release_34  branch at commit
a335ba031b18e2736120b5b82bfee08c50ec522c?
         Jack
ps My goal was to be able to compare the commits already made into clang
svn at llvm.org with the generated diff see how far away we are from a
complete merge.
