* [SCEV] Move ScalarEvolutionExpander.cpp to Transforms/Utils (NFC).Florian Hahn2020-01-041-0/+1
| | | | | | | | | | | | SCEVExpander modifies the underlying function so it is more suitable in Transforms/Utils, rather than Analysis. This allows using other transform utils in SCEVExpander.

* [CodeMoverUtils] Added an API to check if an instruction can be safelyTsang Whitney W.H2019-11-221-0/+1
| | | | | | | | | | | | | | | | | | | moved before another instruction. Summary:Added an API to check if an instruction can be safely moved before another instruction. In future PRs, we will like to add support of moving instructions between blocks that are not control flow equivalent, and add other APIs to enhance usability, e.g. moving basic blocks, moving list of instructions... Loop Fusion will be its first user. When there is intervening code in between two loops, fusion is currently unable to fuse them. Loop Fusion can use this utility to check if the intervening code can be safely moved before or after the two loops, and move them, then it can successfully fuse them.

* [VFABI] Read/Write functions for the VFABI attribute.Francesco Petrogalli2019-11-121-0/+1
| | | | | | | | | | | | | | The attribute is stored at the `FunctionIndex` attribute set, with the name "vector-function-abi-variant".

| | | | | | | | | | | | | In this patch, I'm adding an extra check to the Latch's terminator in llvm::UnrollRuntimeLoopRemainder, similar to how it is already done in the llvm::UnrollLoop.

| | | | | | | | | | | | | | | | Summary: SSAUpdater is a bottleneck in a number of passes, and one of the reasons is that it performs a lot of unnecessary computations (DT/IDF) over and over again. This patch adds a new SSAUpdaterBulk that uses existing DT and avoids recomputing IDF when possible.

The solution is simply put the restore instructions right after the definition of output values instead of putting in exitStub. Unittest for this bug is included.

| | | | | | | | | | | | | | | | | | | | | | | | same basic block. Summary: This problem stems from the fact that instructions are allocated using new in LLVM, i.e. there is no relationship that can be derived by just looking at the pointer value. This interface dispatches to appropriate dominance check given 2 instructions, i.e. in case the instructions are in the same basic block, ordered basicblock (with instruction numbering and caching) are used. Otherwise, dominator tree is used.

This change moves the FunctionComparator (together with the GlobalNumberState utility) in to a separate file so that it can be used by other passes. For example, the SwiftMergeFunctions pass in the Swift compiler: https://github.com/apple/swift/blob/master/lib/LLVMPasses/LLVMMergeFunctions.cpp Details of the change: *) The big part is just moving code out of MergeFunctions.cpp into FunctionComparator.h/cpp *) Make FunctionComparator member functions protected (instead of private) so that a derived comparator class can use them. Following refactoring helps to share code between the base FunctionComparator class and a derived class: *) Add a beginCompare() function *) Move some basic function property comparisons into a separate function compareSignature() *) Do the GEP comparison inside cmpOperations() which now has a new needToCmpOperands reference parameter https://reviews.llvm.org/D25385 llvm-svn: 286632

| | | | | | | | | | | | | | | | | | | Summary: This adds the beginning of an update API to preserve MemorySSA. In particular, this patch adds a way to remove memory SSA accesses when instructions are deleted. It also adds relevant unit testing infrastructure for MemorySSA's API. (There is an actual user of this API, i will make that diff dependent on this one. In practice, a ton of opt passes remove memory instructions, so it's hopefully an obviously useful API :P) Reviewers: hfinkel, reames, george.burgess.iv Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D17157 llvm-svn: 262362

Implement two users of this class: * DFSanABIList in DFSan instrumentation pass. * SanitizerBlacklist in Clang CodeGen library. The latter will be modified to use actual source-level information from frontend (source file names) instead of unstable LLVM IR things (LLVM Module identifier).

* [asan] rewrite asan's stack frame layoutKostya Serebryany2013-12-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Rewrite asan's stack frame layout. First, most of the stack layout logic is moved into a separte file to make it more testable and (potentially) useful for other projects. Second, make the frames more compact by using adaptive redzones (smaller for small objects, larger for large objects). Third, try to minimized gaps due to large alignments (this is hypothetical since today we don't see many stack vars aligned by more than 32). The frames indeed become more compact, but I'll still need to run more benchmarks before committing, but I am sking for review now to get early feedback. This change will be accompanied by a trivial change in compiler-rt tests to match the new frame sizes.

* Completely refactor the structuring of unittest CMake files to match theChandler Carruth2012-06-211-0/+8
Makefiles, the CMake files in every other part of the LLVM tree, and sanity. This should also restore the output tree structure of all the unit tests, sorry for breaking that, and thanks for letting me know. The fundamental change is to put a CMakeLists.txt file in the unittest directory, with a single test binary produced from it. This has several advantages: - No more weird directory stripping in the unittest macro, allowing it to be used more readily in other projects. - No more directory prefixes on all the source files. - Allows correct and precise use of LLVM's per-directory dependency system. - Allows use of the checking logic for source files that have not been added to the CMake build. This uncovered a file being skipped with CMake in LLVM and one in Clang's unit tests. - Makes Specifying conditional compilation or other custom logic for JIT tests easier. It did require adding the concept of an explicit 'optional' source file to the CMake build so that the missing-file check can skip cases where the file is *supposed* to be missing. =] This is another chunk of refactoring the CMake build in order to make it usable for other clients like CompilerRT / ASan / TSan. Note that this is interdependent with a Clang CMake change. llvm-svn: 158909
