* Revert "Support for ThinLTO function importing and symbol linking."Teresa Johnson2015-11-0213-760/+49
| | | | | | | | | | | | | | | | | | | | This reverts commit r251837, due to a number of bot failures of the form: /home/grosser/buildslave/perf-x86_64-penryn-O3-polly-fast/llvm.obj/tools/llvm-link/Release+Asserts/llvm-link.o:llvm-link.cpp:function loadIndex(llvm::LLVMContext&, llvm::Module const*): error: undefined reference to 'llvm::object::FunctionIndexObjectFile::create(llvm::MemoryBufferRef, llvm::LLVMContext&, llvm::Module const*, bool)' /home/grosser/buildslave/perf-x86_64-penryn-O3-polly-fast/llvm.obj/tools/llvm-link/Release+Asserts/llvm-link.o:llvm-link.cpp:function loadIndex(llvm::LLVMContext&, llvm::Module const*): error: undefined reference to 'llvm::object::FunctionIndexObjectFile::takeIndex()' I'm not sure why these are happening - I added Object to the requred libraries in tools/llvm-link/LLVMBuild.txt and the LLVM_LINK_COMPONENTS in tools/llvm-link/CMakeLists.txt.

* Revert part of r239007 related to creating the Python symlink.Zachary Turner2015-11-021-9/+0
| | | | | | | | | | | | | | | This has apparently been broken since June, but only on non-Windows. Perhaps nobody noticed it because if the symlink is already there it won't try to re-create it, and nobody ever tried doing a clean build. In any case, I will let the original author attempt to fix this if he is still interested. the problem is that in the normal case of not setting BUILD_SHARED_LIBS and simply running ninja, it would link _lldb.so to a non-existent location, creating a dangling symlink. llvm-svn: 251840
* [IndVarSimplify] Rewrite loop exit values with their initial values from ↵Chen Li2015-11-023-1/+149
| | | | | | | | | | | | | | | | | loop preheader Summary: This patch adds support to check if a loop has loop invariant conditions which lead to loop exits. If so, we know that if the exit path is taken, it is at the first loop iteration. If there is an induction variable used in that exit path whose value has not been updated, it will keep its initial value passing from loop preheader. We can therefore rewrite the exit value with its initial value. This will help remove phis created by LCSSA and enable other optimizations like loop unswitch.

* Support for ThinLTO function importing and symbol linking.Teresa Johnson2015-11-0213-49/+760
| | | | | | | | | | | | | | | | | | | | | Summary: Support for necessary linkage changes and symbol renaming during ThinLTO function importing. Also includes llvm-link support for manually importing functions and associated llvm-link based tests. Note that this does not include support for intelligently importing metadata, which is currently imported duplicate times. That support will be in the follow-on patch, and currently is ignored by the tests.

* In MachineBlockPlacement, filter cold blocks off the loop chain when profile ↵Cong Hou2015-11-022-2/+168
| | | | | | | | | | | | | | | | | | | | | | | | | | | data is available. In the current BB placement algorithm, a loop chain always contains all loop blocks. This has a drawback that cold blocks in the loop may be inserted on a hot function path, hence increasing branch cost and also reducing icache locality. Consider a simple example shown below: A | B⇆C | D When B->C is quite cold, the best BB-layout should be A,B,D,C. But the current implementation produces A,C,B,D. This patch filters those cold blocks off from the loop chain by comparing the ratio: LoopBBFreq / LoopFreq to 20%: if it is less than 20%, we don't include this BB to the loop chain. Here LoopFreq is the frequency of the loop when we reduce the loop into a single node. In general we have more cold blocks when the loop has few iterations. And vice versa.

* [PTH] Fix data length used for stat cache entriesReid Kleckner2015-11-021-1/+1
| | | | | | | | | | | | | | This came up in a boost build, which apparently uses PTH. This was broken in r187619 when we migrated it to uses llvm::fs instead of raw stat calls. Constructing a test case with a hash table collision in-tree is tough. Instead, I have a pending change to OnDiskChainedHashTable that asserts that the reported length of the data agrees with the data actually written. All of the existing in-tree tests find the bug with this assert. llvm-svn: 251828

* Make dosep correctly invoke the top-level script when forking outZachary Turner2015-11-022-6/+6
| | | | | | | | | | | | | | | | | | | | packages/Python/lldbsuite is now a Python package, and it relies on its __init__.py being called to do package-level initialization. If you exec packages/Python/lldbsuite/dotest.py directly, you won't get this package level initialization, and things will fail. But without this patch, this is exactly what dosep itself does. To launch the multi-processing fork, it was hardcoding a path to dotest.py and exec'ing it from inside the package. The fix here is to get the path of the top-level script, and then exec'ing that instead. A more robust solution would involve refactoring the code so that dosep execs some internal script that imports lldbsuite, but that's a bit more involved.

* Fix two issues in MergeConsecutiveStores:James Y Knight2015-11-024-13/+72
| | | | | | | | | | | | | | | | | | | | | | 1) PR25154. This is basically a repeat of PR18102, which was fixed in r200201, and broken again by r234430. The latter changed which of the store nodes was merged into from the first to the last. Thus, we now also need to prefer merging a later store at a given address into the target node, instead of an earlier one. 2) While investigating that, I also realized I'd introduced a bug in r236850. There, I removed a check for alignment -- not realizing that nothing except the alignment check was ensuring that none of the stores were overlapping! This is a really bogus way to ensure there's no aliased stores. A better solution to both of these issues is likely to always use the code added in the 'if (UseAA)' branches which rearrange the chain based on a more principled analysis. I'll look into whether that can be used always, but in the interest of getting things back to working, I think a minimal change makes sense. llvm-svn: 251816

* [SCEV][LV] Add SCEV Predicates and use them to re-implement stride versioningSilviu Baranga2015-11-027-132/+516
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: SCEV Predicates represent conditions that typically cannot be derived from static analysis, but can be used to reduce SCEV expressions to forms which are usable for different optimizers. ScalarEvolution now has the rewriteUsingPredicate method which can simplify a SCEV expression using a SCEVPredicateSet. The normal workflow of a pass using SCEVPredicates would be to hold a SCEVPredicateSet and every time assumptions need to be made a new SCEV Predicate would be created and added to the set. Each time after calling getSCEV, the user will call the rewriteUsingPredicate method. We add two types of predicates SCEVPredicateSet - implements a set of predicates SCEVEqualPredicate - tests for equality between two SCEV expressions We use the SCEVEqualPredicate to re-implement stride versioning. Every time we version a stride, we will add a SCEVEqualPredicate to the context. Instead of adding specific stride checks, LoopVectorize now adds a more generic SCEV check. We only need to add support for this in the LoopVectorizer since this is the only pass that will do stride versioning.
