* Revert r194865 and r194874.Alexey Samsonov2013-11-18
| | | | | | | | | | | | | This change is incorrect. If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class. As a result, I observe plently of memory leaks. Notable examples I investigated are: ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194997 91177308-0d34-0410-b5e6-96231b3b80d8

* [block-freq] Add BlockFrequency::scale that returns a remainder from the ↵Michael Gottesman2013-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | division and make the private scale in BlockFrequency more performant. This change is the first in a series of changes improving LLVM's Block Frequency propogation implementation to not lose probability mass in branchy code when propogating block frequency information from a basic block to its successors. This patch is a simple infrastructure improvement that does not actually modify the block frequency algorithm. The specific changes are: 1. Changes the division algorithm used when scaling block frequencies by branch probabilities to a short division algorithm. This gives us the remainder for free as well as provides a nice speed boost. When I benched the old routine and the new routine on a Sandy Bridge iMac with disabled turbo mode performing 8192 iterations on an array of length 32768, I saw ~600% increase in speed in mean/median performance. 2. Exposes a scale method that returns a remainder. This is important so we can ensure that when we scale a block frequency by some branch probability BP = N/D, the remainder from the division by D can be retrieved and propagated to other children to ensure no probability mass is lost (more to come on this). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194950 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-cov: Slightly improved error checking.Yuchen Wu2013-11-14
| | | | | | | | - readInt() should check all 4 bytes can be read, not just 1. - In the event of false data in the gcno file, it was possible to index into a non-existent index of SmallVector, causing assertion error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194639 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-cov: Removed StringMap holding GCOVLines.Yuchen Wu2013-11-14
| | | | | | | | | | | | | | | | | According to the hazy gcov documentation, it appeared to be technically possible for lines within a block to belong to different source files. However, upon further investigation, gcov does not actually support multiple source files for a single block. This change removes a level of separation between blocks and lines by replacing the StringMap of GCOVLines with a SmallVector of ints representing line numbers. This also means that the GCOVLines class is no longer needed. This paves the way for supporting the "-a" option, which will output block information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194637 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-cov: Replaced asserts with proper error handling.Yuchen Wu2013-11-14
| | | | | | | | | | | | | | Unified the interface for read functions. They all return a boolean indicating if the read from file succeeded. Functions that previously returned the read value now store it into a variable that is passed in by reference instead. Callers will need to check the return value to detect if an error occurred. Also added a new test which ensures that no assertions occur when file contains invalid data. llvm-cov should return with error code 1 upon failure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194635 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove another unused, and IMHO, not very desirable feature of ErrorOr.Rafael Espindola2013-11-05
| | | | | | | | | | | | | | | | | | One of the uses of the IsValid flag is to support default constructing a ErrorOr that is not a Error or a Value. There is not much value in doing that IMHO. If ErrorOr was to have a default constructor, it should be implemented by default constructing the value, but even that looks unnecessary. The other use is to avoid calling destructors on moved objects. This looks wrong. If the data being moved has non trivial treatment of moves (an std::vector for example), it is its destructor that should handle it, not ~ErrorOr. With this change ErrorOr becomes a fairly simple wrapper and should always be better than using an error_code + value in an API. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194109 91177308-0d34-0410-b5e6-96231b3b80d8
* Support for reading run counts in llvm-cov.Yuchen Wu2013-11-05
| | | | | | | | | | | | This patch enables llvm-cov to correctly output the run count stored in the GCDA file. GCOVProfiling currently does not generate this information, so the GCDA run data had to be hacked on from a GCDA file generated by gcc. This is corrected by a subsequent patch. With the run and program data included, both llvm-cov and gcov produced the same output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194033 91177308-0d34-0410-b5e6-96231b3b80d8

* Simplify ErrorOr.Rafael Espindola2013-11-05
| | | | | | | | | | | | | | | | ErrorOr had quiet a bit of complexity and indirection to be able to hold a user type with the error. That feature is not used anymore. This patch removes it, it will live in svn history if we ever need it again. If we do need it again, IMHO there is one thing that should be done differently: Holding extra info in the error is not a property a function also returning a value or not. The ability to hold extra info should be in the error type and ErrorOr templated over it so that we don't need the funny looking ErrorOr<void>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194030 91177308-0d34-0410-b5e6-96231b3b80d8

* Support for reading program counts in llvm-cov.Yuchen Wu2013-10-25
| | | | | | | | | | | | | llvm-cov will now be able to read program counts from the GCDA file and output it in the same format as gcov. The program summary tag was identified from gcov-io.h as "\0\0\0\a3". There is currently a bug in GCOVProfiling.cpp which does not generate the run- or program-counting IR, so this change was tested manually by modifying the GCDA file and comparing the gcov and llvm-cov outputs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193389 91177308-0d34-0410-b5e6-96231b3b80d8

* Fixed llvm-cov to count edges instead of blocks.Yuchen Wu2013-10-24
| | | | | | | | | | | | | | | | | This was a fundamental flaw in llvm-cov where it treated the values in the GCDA files as block counts instead of edge counts. This created incorrect line counts when branching was present. Instead, the edge counts should be summed to obtain the correct block count. The fix was tested using custom test files as well as single source files from the test-suite directory. The behaviour can be verified by reading the GCOV documentation that describes the GCDA spec ("ARC_COUNTS gives the counter values for those arcs that are instrumented") and the header description provided by GCOVProfiling.cpp ("instruments the code that runs to records (sic) the edges between blocks that run and emit a complementary "gcda" file on exit"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193299 91177308-0d34-0410-b5e6-96231b3b80d8
* Use a map instead of vector to store line counts.Yuchen Wu2013-10-23
| | | | | | | | | | | | There are a few motivations for this: - Using a map allows for checking if line is in map. This differentiates unexecutable lines (such as comments) from unexecuted logical lines of code. "#####" is now outputted in this case, in line with gcov. - Source files are no longer read in twice: once when storing the line counts, and once when outputting the data. - Greatly simplifies the function FileInfo::addLineCount(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193264 91177308-0d34-0410-b5e6-96231b3b80d8
