* [libFuzzer] Fix DataFlow.cpp logic when tracing long inputs.Max Moroz2019-04-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: 1. Do not create DFSan labels for the bytes which we do not trace. This is where we run out of labels at the first place. 2. When dumping the traces on the disk, make sure to offset the label identifiers by the number of the first byte in the trace range. 3. For the last label, make sure to write it at the last position of the trace bit string, as that label represents the input size, not any particular byte. Also fixed the bug with division in python which I've introduced when migrated the scripts to Python3 (`//` is required for integral division). Otherwise, the scripts are wasting too much time unsuccessfully trying to collect and process traces from the long inputs.

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-193-12/+9
| | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@351636 91177308-0d34-0410-b5e6-96231b3b80d8
