* [DebugInfo] add SectionedAddress to DebugInfo interfaces.Alexey Lapshin2019-02-271-30/+43
| | | | | | | | | | | | | | | | | That patch is the fix for https://bugs.llvm.org/show_bug.cgi?id=40703 "wrong line number info for obj file compiled with -ffunction-sections" bug. The problem happened with only .o files. If object file contains several .text sections then line number information showed incorrectly. The reason for this is that DwarfLineTable could not detect section which corresponds to specified address(because address is the local to the section). And as the result it could not select proper sequence in the line table. The fix is to pass SectionIndex with the address. So that it would be possible to differentiate addresses from various sections. With this fix llvm-objdump shows correct line numbers for disassembled code.

* 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 Phillips2017-11-031-0/+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.

* Graph builder implementation.Mitch Phillips2017-10-231-0/+552
Implement a localised graph builder for indirect control flow instructions. Main interface is through GraphBuilder::buildFlowGraph, which will build a flow graph around an indirect CF instruction. Various modifications to FileVerifier are also made to const-expose some members needed for machine code analysis done by the graph builder.
