* Fix gcc7 -Wdangling-else warning. NFCI.Simon Pilgrim2018-12-201-2/+4
| | | | llvm-svn: 349760
* Fix use-after-free with profile remapping.Richard Smith2018-12-191-0/+4
| | | | | | | | We need to keep the underlying profile reader alive as long as the profile data, because the profile data may contain StringRefs referring to strings in the reader's name table. llvm-svn: 349600
* Support for remapping profile data when symbols change, for sample-basedRichard Smith2018-10-101-19/+40

* Use createTemporaryFile in SampleProfTestAlexander Kornienko2018-09-171-3/+5
| | | | | | | | Create a temporary file in the system temporary directory instead of creating a file in the current directory, which may be not writable. (Fix for an issue introduced in r342283.) llvm-svn: 342386
* Fix filesystem race issue in SampleProfTest introduced in rL342283.Wei Mi2018-09-151-11/+9
| | | | | | | | | Before this fix, multiple invocations of testRoundTrip will create multiple writers which share the same file as output destination. That could introduce filesystem race issue when multiple subtests are executed concurrently. This patch assign writers with different files as their output destinations. llvm-svn: 342301
* [SampleFDO] Add FunctionOffsetTable in compact binary format profile.Wei Mi2018-09-141-6/+14
| | | | | | | | | | | | The patch saves a function offset table which maps function name index to the offset of its function profile to the start of the binary profile. By using the function offset table, for those function profiles which will not be used when compiling a module, the profile reader does't have to read them. For profile size around 10~20M, it saves ~10% compile time. Differential Revision: https://reviews.llvm.org/D51863 llvm-svn: 342283
* [NFC] Change sample profile format enum name SPF_Raw_Binary to SPF_Binary.Wei Mi2018-06-121-1/+1
| | | | | | | Some out-of-tree targets depend on the enum name SPF_Binary. Keep the name can avoid unnecessary churn to those targets. llvm-svn: 334476
* [SampleFDO] Add a new compact binary format for sample profile.Wei Mi2018-06-111-9/+26
| | | | | | | | | | | | | | Name table occupies a big chunk of size in current binary format sample profile. In order to reduce its size, the patch changes the sample writer/reader to save/restore MD5Hash of names in the name table. Sample annotation phase will also use MD5Hash of name to query samples accordingly. Experiment shows compact binary format can reduce the size of sample profile by 2/3 compared with binary format generally. Differential Revision: https://reviews.llvm.org/D47955 llvm-svn: 334447
* [SampleFDO] Extend SampleProfReader to handle demangled names.Wei Mi2018-03-071-0/+8
| | | | | | | | | | | | | SampleProfReader assumes function names in the profile are all mangled names. However, there are cases that few demangled names are somehow contained in the profile (usually because of debug info problems), which may trigger parsing error in SampleProfReader and cause the whole profile to be unusable. The patch extends SampleProfReader to handle profiles with demangled names, so that those profiles can still be useful. Differential revision: https://reviews.llvm.org/D44161 llvm-svn: 326905
* Remove redundant includes from unittests.Michael Zolotukhin2017-12-131-6/+0

* Re-sort #include lines for unittests. This uses a slightly modifiedChandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | clang-format (https://reviews.llvm.org/D33932) to keep primary headers at the top and handle new utility headers like 'gmock' consistently with other utility headers. No other change was made. I did no manual edits, all of this is clang-format. This should allow other changes to have more clear and focused diffs, and is especially motivated by moving some headers into more focused libraries. llvm-svn: 304786
* Use the range variant of find_if instead of unpacking begin/endDavid Majnemer2016-08-121-6/+4
| | | | | | No functionality change is intended. llvm-svn: 278443
* Remove specializations of ProfileSummaryEaswaran Raman2016-05-191-13/+10
| | | | | | | | This removes the subclasses of ProfileSummary, moves the members of the derived classes to the base class. Differential Revision: http://reviews.llvm.org/D20390 llvm-svn: 270143
* Fix some Clang-tidy modernize and Include What You Use warnings.Eugene Zelenko2016-04-281-4/+18

* Remove every uses of getGlobalContext() in LLVM (but the C API)Mehdi Amini2016-04-141-3/+4
| | | | | | | | | | | At the same time, fixes InstructionsTest::CastInst unittest: yes you can leave the IR in an invalid state and exit when you don't destroy the context (like the global one), no longer now.

* Sample profile summary cleanupEaswaran Raman2016-03-281-1/+1
| | | | | | | | Replace references to MaxHeadSamples with MaxFunctionCount Differential Revision: http://reviews.llvm.org/D18522 llvm-svn: 264686
* Interface to get/set profile summary metadata to moduleEaswaran Raman2016-03-181-0/+13

* Use LineLocation instead of CallsiteLocation to index callsite profile.Dehao Chen2016-03-031-0/+2
| | | | | | | | | | | | Summary: With discriminator, LineLocation can uniquely identify a callsite without the need to specifying callee name. Remove Callee function name from the key, and put it in the value (FunctionSamples).

* Metadata support for profile summary.Easwaran Raman2016-03-011-24/+37
| | | | | | | | This adds support to convert ProfileSummary object to Metadata and create a ProfileSummary object from metadata. This would allow attaching profile summary information to Module allowing optimization passes to use it. llvm-svn: 262360
* Add profile summary support for sample profile.Easwaran Raman2016-02-191-0/+30

* [PGO] Handle and report overflow during profile merge for all types of dataNathan Slingerland2015-12-161-0/+30
| | | | | | | | | | | | Summary: Surface counter overflow when merging profile data. Merging still occurs on overflow but counts saturate to the maximum representable value. Overflow is reported to the user. Reviewers: davidxl, dnovillo, silvas Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D15547 llvm-svn: 255825
* [ProfileData] Add unit test infrastructure for sample profile reader/writerNathan Slingerland2015-12-101-0/+102
Summary: Adds support for in-memory round-trip of sample profile data along with basic round trip unit tests. This will also make it easier to include unit tests for future changes to sample profiling.
