* [Cost][X86] Add v2i64 truncation costsSimon Pilgrim2019-09-226-121/+173
| | | | | | | | We are missing costs for a lot of truncation cases, I'm hoping to address all the 'zero cost' cases in trunc.ll I thought this was a vector widening side effect, but even before this we had some interesting LV decisions (notably over indvars) being made due to these zero costs. llvm-svn: 372498
* Clang-format: Add Whitesmiths indentation stylePaul Hoad2019-09-226-0/+343
| | | | | | | | | | | | | | | | | | | | | Summary: This patch adds support for the Whitesmiths indentation style to clang-format. It’s an update to a patch submitted in 2015 (D6833), but reworks it to use the newer API. There are still some issues with this patch, primarily around `switch` and `case` support. The added unit test won’t currently pass because of the remaining issues.

[SampleFDO] Expose an interface to return the size of a section or the size of the profile for profile in ExtBinary format. Sometimes we want to limit the size of the profile by stripping some functions with low sample count or by stripping some function names with small text size from profile symbol list. That requires the profile reader to have the interfaces returning the size of a section or the size of total profile. The patch add those interfaces. At the same time, add some dump facility to show the size of each section. Differential revision: https://reviews.llvm.org/D67726 llvm-svn: 372478

* [MachinePipeliner] Improve the TargetInstrInfo API analyzeLoop/reduceLoopCountJames Molloy2019-09-2110-194/+253
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recommit: fix asan errors. The way MachinePipeliner uses these target hooks is stateful - we reduce trip count by one per call to reduceLoopCount. It's a little overfit for hardware loops, where we don't have to worry about stitching a loop induction variable across prologs and epilogs (the induction variable is implicit). This patch introduces a new API: /// Analyze loop L, which must be a single-basic-block loop, and if the /// conditions can be understood enough produce a PipelinerLoopInfo object. virtual std::unique_ptr<PipelinerLoopInfo> analyzeLoopForPipelining(MachineBasicBlock *LoopBB) const; The return value is expected to be an implementation of the abstract class: /// Object returned by analyzeLoopForPipelining. Allows software pipelining /// implementations to query attributes of the loop being pipelined. class PipelinerLoopInfo { public: virtual ~PipelinerLoopInfo(); /// Return true if the given instruction should not be pipelined and should /// be ignored. An example could be a loop comparison, or induction variable /// update with no users being pipelined. virtual bool shouldIgnoreForPipelining(const MachineInstr *MI) const = 0; /// Create a condition to determine if the trip count of the loop is greater /// than TC. /// /// If the trip count is statically known to be greater than TC, return /// true. If the trip count is statically known to be not greater than TC, /// return false. Otherwise return nullopt and fill out Cond with the test /// condition. virtual Optional<bool> createTripCountGreaterCondition(int TC, MachineBasicBlock &MBB, SmallVectorImpl<MachineOperand> &Cond) = 0; /// Modify the loop such that the trip count is /// OriginalTC + TripCountAdjust. virtual void adjustTripCount(int TripCountAdjust) = 0; /// Called when the loop's preheader has been modified to NewPreheader. virtual void setPreheader(MachineBasicBlock *NewPreheader) = 0; /// Called when the loop is being removed. virtual void disposed() = 0; }; The Pipeliner (ModuloSchedule.cpp) can use this object to modify the loop while allowing the target to hold its own state across all calls. This API, in particular the disjunction of creating a trip count check condition and adjusting the loop, improves the code quality in ModuloSchedule.cpp. llvm-svn: 372463

* Stop tracking atexit/__cxa_atexit/pthread_atfork allocations in LSan/NetBSDKamil Rytarowski2019-09-214-1/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The atexit(3) and __cxa_atexit() calls allocate internally memory and free on exit, after executing all callback. This causes false positives as DoLeakCheck() is called from the atexit handler. In the LSan/ASan tests there are strict checks triggering false positives here. Intercept all atexit(3) and __cxa_atexit() calls and disable LSan when calling the real functions. Stop tracing allocations in pthread_atfork(3) funtions, as there are performed internal allocations that are not freed for the time of running StopTheWorld() code. This avoids false-positives. The same changes have to be replicated in the ASan and LSan runtime. Non-NetBSD OSs are not tested and this code is restricted to NetBSD only.
