* Remove esan.Nico Weber2019-03-111-95/+0
| | | | | | | | | | | It hasn't seen active development in years, and it hasn't reached a state where it was useful. Remove the code until someone is interested in working on it again. Differential Revision: https://reviews.llvm.org/D59133 llvm-svn: 355862
* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* [esan|wset] Add 8-level working set snapshot accumulationDerek Bruening2016-06-031-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: Adds a new option -snapshot_step controlling the frequency distribution for an 8-level series of samples using each bit of each shadow byte. Implements accumulation from each level to the next higher level at the specified frequency. Adds storage of the 8 series of samples using CircularBuffer instances. Fixes an error in the circular buffer data structure where a static object's destructor will be called too early. Prints the results out at the end in a simple manner to give us something to start with. Updates the workingset-samples test to test the new feature.

* [esan] Add circular buffer data structureDerek Bruening2016-05-311-0/+92
Summary: Adds a new class, CircularBuffer, for holding a wrap-around fixed-size sequence of a primitive data type. This will be used initially by the working set tool. Adds a unit test for CircularBuffer, including infrastructure support to include esan headers and to link with the esan library by pretending to want the working set tool.
