@gbiv already got all my shell quoting comments.
I think we should do one more round of fixes, we can commit that for you, and
then move on to the next steps.
================
Comment at: clang/utils/creduce-clang-crash.py:109
+ open(testfile, 'w').write('\n'.join(test_contents))
+ os.chmod(testfile, os.stat(testfile).st_mode | stat.S_IEXEC)
+
----------------
We could try validating that the interestingness test passes here. If it
doesn't, that's a bug in this script, I suppose.
CReduce already does this for the user, but it's not clear with our usage model
how to do this.
================
Comment at: clang/utils/creduce-clang-crash.py:110
+ os.chmod(testfile, os.stat(testfile).st_mode | stat.S_IEXEC)
+
+ # Call C-Reduce
----------------
Let's add a TODO (or FIXME, that's more LLVM-y) here to add a step that runs
the full pre-processor with -E and -P here. As we've discussed, it often
doesn't work, but when it does, it avoids all those issues with #defines,
comments, etc, breaking up topformflat. This doesn't have to be in the first
version, of course.
I see @joerg added a comment about this as well.
