I only know how to disable the test of a full directory, so if you want I can
disable all the CodeGen directory (and subdirectories) when Cloog is not
available.  Note that in my first patch I have moved only those tests not
working without cloog, and there are several testcases left in CodeGen that can
still be executed with ISL's codegen.

That's what patch 3 does, except for a minor rename to avoid a redundant
CodeGen
in the dir names.

I did not realize there are tests that work for both.
What are those tests doing?

I was basically aiming for having one test directory for one LLVM-IR 
pass. Instead of having shared test cases, I would rather copy those 
tests to the isl directory.

Here is what is left in my CodeGen dir:

polly/test/CodeGen$ find . -name '*.ll'
./20100708.ll
./single_loop_ull_max_iterations.ll
./single_loop_uint_max_iterations.ll
./reduction.ll
./single_do_loop_one_iteration.ll
./OpenMP/20120330-argument-use.ll
./OpenMP/simple_nested_loop.ll
./OpenMP/structnames.ll
./OpenMP/parallel_loop_simple2.ll
./OpenMP/copy_in_temporary.ll
./OpenMP/parallel_loop_simple.ll
./OpenMP/clastvar_after_parallel_loop.ll
./OpenMP/add_memref.ll
./OpenMP/copy_in_argument.ll
./OpenMP/invalidate_subfn_scops.ll
./OpenMP/two_loop.ll
./OpenMP/parallel_loop.ll
./OpenMP/param_referenced_in_stmt.ll
./OpenMP/extract_memref.ll
./scev.ll
./single_do_loop_int_param_iterations.ll
./MemAccess/simple_analyze.ll
./MemAccess/simple.ll
./20110312-Fail-without-basicaa.ll
./GPGPU/3d_innermost_non_parallel.ll
./GPGPU/2d_innermost_parallel.ll
./test.ll

The OpenMP ones are already guarded with have_cloog, and the GPGPU ones are also
guarded.

I could move all these except OpenMP/GPGPU to the Cloog/CodeGen dir.

Then let's not use CodeGen for the Cloog code gen dir.  I have used
Cloog/CodeGen and Isl/CodeGen and I think this is consistent with what you want.

I can then move the remaining tests in Cloog/CodeGen and duplicate them in
Isl/CodeGen.  What do you think?
