* 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
* [cfi-verify] Add blacklist parsing for result filtering.Mitch Phillips2017-11-031-1/+1
| | | | | | | | | | | | | | | | | | | | | Adds blacklist parsing behaviour for filtering results into four categories: - Expected Protected: Things that are not in the blacklist and are protected. - Unexpected Protected: Things that are in the blacklist and are protected. - Expected Unprotected: Things that are in the blacklist and are unprotected. - Unexpected Unprotected: Things that are not in the blacklist and are unprotected. now can optionally be invoked with a second command line argument, which specifies the blacklist file that the binary was built with.

* Parse DWARF information to reduce false positives.Mitch Phillips2017-10-311-1/+1
| | | | | | | | | | | | | | Summary: Help differentiate code and data by parsing DWARF information. This will reduce false positive rates where data is placed in executable sections and is mistakenly parsed as code, resulting in an inflation in the number of indirect CF instructions (and hence an inflation of the number of unprotected). Also prints the DWARF line data around the region of each indirect CF instruction.

| | | | | | | | | | | | | | | | Summary: Resubmission of D37937. Fixed i386 target building (conversion from std::size_t& to uint64_t& failed). Fixed documentation warning failure about docs/CFIVerify.rst not being in the tree.

* Introduce the llvm-cfi-verify tool.Vlad Tsyrklevich2017-09-191-0/+22
Summary: Introduces the llvm-cfi-verify tool to llvm. Includes the design document (docs/CFIVerify.rst). Current implementation of the tool is simply a disassembler that identifies and prints the indirect control flow instructions.
