2012-11-01As I'm going to be touching several comments in this file, update theChandler Carruth
'@brief' doxygen markup to the now standard '\brief' markup form, in conformance with the coding standards. This will let me continue to write new comments in this form without making things inconsistent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167225 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-01Teach Type::getPointerAddressSpace to look through pointer vectorsChandler Carruth
politely and document this feature. This simple API extension then allows us to write all of the Instructions' address space query methods much more simply. No functionality change intended here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167223 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-01Revert the majority of the next patch in the address space series:Chandler Carruth
r165941: Resubmit the changes to llvm core to update the functions to support different pointer sizes on a per address space basis. Despite this commit log, this change primarily changed stuff outside of VMCore, and those changes do not carry any tests for correctness (or even plausibility), and we have consistently found questionable or flat out incorrect cases in these changes. Most of them are probably correct, but we need to devise a system that makes it more clear when we have handled the address space concerns correctly, and ideally each pass that gets updated would receive an accompanying test case that exercises that pass specificaly w.r.t. alternate address spaces. However, from this commit, I have retained the new C API entry points. Those were an orthogonal change that probably should have been split apart, but they seem entirely good. In several places the changes were very obvious cleanups with no actual multiple address space code added; these I have not reverted when I spotted them. In a few other places there were merge conflicts due to a cleaner solution being implemented later, often not using address spaces at all. In those cases, I've preserved the new code which isn't address space dependent. This is part of my ongoing effort to clean out the partial address space code which carries high risk and low test coverage, and not likely to be finished before the 3.2 release looms closer. Duncan and I would both like to see the above issues addressed before we return to these changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167222 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-01Revert the series of commits starting with r166578 which introduced theChandler Carruth
getIntPtrType support for multiple address spaces via a pointer type, and also introduced a crasher bug in the constant folder reported in PR14233. These commits also contained several problems that should really be addressed before they are re-committed. I have avoided reverting various cleanups to the DataLayout APIs that are reasonable to have moving forward in order to reduce the amount of churn, and minimize the number of commits that were reverted. I've also manually updated merge conflicts and manually arranged for the getIntPtrType function to stay in DataLayout and to be defined in a plausible way after this revert. Thanks to Duncan for working through this exact strategy with me, and Nick Lewycky for tracking down the really annoying crasher this triggered. (Test case to follow in its own commit.) After discussing with Duncan extensively, and based on a note from Micah, I'm going to continue to back out some more of the more problematic patches in this series in order to ensure we go into the LLVM 3.2 branch with a reasonable story here. I'll send a note to llvmdev explaining what's going on and why. Summary of reverted revisions: r166634: Fix a compiler warning with an unused variable. r166607: Add some cleanup to the DataLayout changes requested by Chandler. r166596: Revert "Back out r166591, not sure why this made it through since I cancelled the command. Bleh, sorry about this! r166591: Delete a directory that wasn't supposed to be checked in yet. r166578: Add in support for getIntPtrType to get the pointer type based on the address space. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167221 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-01BBVectorize: Account for internal shuffle costsHal Finkel
When target costs are available, use them to account for the costs of shuffles on internal edges of the DAG of candidate pairs. Because the shuffle costs here are currently for only the internal edges, the current target cost model is trivial, and the chain depth requirement is still in place, I don't yet have an easy test case. Nevertheless, by looking at the debug output, it does seem to do the right think to the effective "size" of each DAG of candidate pairs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167217 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-31BBVectorize: Choose pair ordering to minimize shufflesHal Finkel
BBVectorize would, except for loads and stores, always fuse instructions so that the first instruction (in the current source order) would always represent the low part of the input vectors and the second instruction would always represent the high part. This lead to too many shuffles being produced because sometimes the opposite order produces fewer of them. With this change, BBVectorize tracks the kind of pair connections that form the DAG of candidate pairs, and uses that information to reorder the pairs to avoid excess shuffles. Using this information, a future commit will be able to add VTTI-based shuffle costs to the pair selection procedure. Importantly, the number of remaining shuffles can now be estimated during pair selection. There are some trivial instruction reorderings in the test cases, and one simple additional test where we certainly want to do a reordering to avoid an unnecessary shuffle. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167122 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-31Do simple constant propagation in lookup table formation for switchesHans Wennborg
By propagating the value for the switch condition, LLVM can now build lookup tables for code such as: switch (x) { case 1: return 5; case 2: return 42; case 3: case 4: case 5: return x - 123; default: return 123; } Given that x is known for each case, "x - 123" becomes a constant for cases 3, 4, and 5. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167115 91177308-0d34-0410-b5e6-96231b3b80d8
