Manually upgrade the test suite to specify the flag to cttz and ctlz.
I followed three heuristics for deciding whether to set 'true' or
'false':

- Everything target independent got 'true' as that is the expected
  common output of the GCC builtins.
- If the target arch only has one way of implementing this operation,
  set the flag in the way that exercises the most of codegen. For most
  architectures this is also the likely path from a GCC builtin, with
  'true' being set. It will (eventually) require lowering away that
  difference, and then lowering to the architecture's operation.
- Otherwise, set the flag differently dependending on which target
  operation should be tested.

Let me know if anyone has any issue with this pattern or would like
specific tests of another form. This should allow the x86 codegen to
just iteratively improve as I teach the backend how to differentiate
between the two forms, and everything else should remain exactly the
same.

indicates whether the intrinsic has a defined result for a first

accurately model the semantics of GCC's __builtin_ctz and __builtin_clz
and the X86 instructions (prior to AVX) which implement them.

This patch merely sets the stage by extending the signature of these
intrinsics and establishing auto-upgrade logic so that the old spelling
still works both in IR and in bitcode. The upgrade logic preserves the
existing (inefficient) semantics. This patch should not change any
behavior. CodeGen isn't updated because it can use the existing
semantics regardless of the flag's value.

Chandler Carruth [Sat, 10 Dec 2011 09:41:13 +0000 (09:41 +0000)]
At the request of Michael Spencer, make the VCS version detection logic
in CMake a bit more handy. Previously we would get such charming
versions as the following for revision NNNN and commit-ish XXXXX:
  3.1svnsvn-rNNNN
  3.1svngit-svn-rNNNN
  3.1svngit-svn-XXXXX

The mechanism selecting betwene the latter two was particularly odd, and
didn't work with all of the ways git-svn repos are set up apparently. It
also misses an important point -- both the revision *and* the git commit
might be relevant when working on a local branch some distance from
mainline. The new logic does several things:

1) It strips the redundant initial 'svn'.
2) It always looks for a git-svn revision number base, and when found
   includes it in the version.
3) If the git commit-ish for the current HEAD is not exactly that
   revision number, it is also included.

The resulting strings should roughly be:
  3.1svn-rNNNN
  3.1git-svn-rNNNN
  3.1git-svn-rNNNN-XXXXX

Suggestions on formatting etc always welcome. =] I've only looked at the
LLVM version string here, not Clang's (yet).

Note that the commit-ish reported is *not* terribly accurate. It updates
when 'cmake' is run, not when the binary is built. Still, it may be
better than nothing, especially if people have fairly long-lived git
repos and branches. This is not a new limitation, just didn't want
anyone to be surprised.
