2011-12-12Update the LangRef documentation for llvm.ctlz and llvm.cttz to specifyChandler Carruth
the behavior with the newly added flag for undefined results on a zero input. I'm terrible at documentation, so comments and suggestions welcome here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146361 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-12Teach the verifier to reject all non-constant arguments to the secondChandler Carruth
argument of the cttz and ctlz intrinsics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146360 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-12Switch llvm.cttz and llvm.ctlz to accept a second i1 parameter whichChandler Carruth
indicates whether the intrinsic has a defined result for a first argument equal to zero. This will eventually allow these intrinsics to 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. Note that this will be followed by API updates to Clang and DragonEgg.

2011-12-10Teach the VCS detection to set some root-level variables with the rawChandler Carruth
revision and git commit data extracted. This will be used in the Clang CMake build to avoid trying to re-detect the information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146324 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-10At the request of Michael Spencer, make the VCS version detection logicChandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146323 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-10Try to align the point where a large basic block is split.Jakob Stoklund Olesen
The split point is picked such that the newly created water has the same alignment as the function. This makes the island suitable for constant pool entries with potentially higher alignment. This also fixes an issue where the basic block was split one instruction too late, causing nonconvergence of the algorithm. <rdar://problem/10550705> There is still an issue with correctly packing differently aligned entries in the island. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146314 91177308-0d34-0410-b5e6-96231b3b80d8
