* [Remarks] Add string deduplication using a string tableFrancis Visoiu Mistrih2019-04-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add support for uniquing strings in the remark streamer and emitting the string table in the remarks section. * Add parsing support for the string table in the RemarkParser. From this remark: ``` --- !Missed Pass: inline Name: NoDefinition DebugLoc: { File: 'test-suite/SingleSource/UnitTests/2002-04-17-PrintfChar.c', Line: 7, Column: 3 } Function: printArgsNoRet Args: - Callee: printf - String: ' will not be inlined into ' - Caller: printArgsNoRet DebugLoc: { File: 'test-suite/SingleSource/UnitTests/2002-04-17-PrintfChar.c', Line: 6, Column: 0 } - String: ' because its definition is unavailable' ... ``` to: ``` --- !Missed Pass: 0 Name: 1 DebugLoc: { File: 3, Line: 7, Column: 3 } Function: 2 Args: - Callee: 4 - String: 5 - Caller: 2 DebugLoc: { File: 3, Line: 6, Column: 0 } - String: 6 ... ``` And the string table in the .remarks/__remarks section containing: ``` inline\0NoDefinition\0printArgsNoRet\0 test-suite/SingleSource/UnitTests/2002-04-17-PrintfChar.c\0printf\0 will not be inlined into \0 because its definition is unavailable\0 ``` This is mostly supposed to be used for testing purposes, but it gives us a 2x reduction in the remark size, and is an incremental change for the updates to the remarks file format.

* 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
* Move Object format code to lib/BinaryFormat.Zachary Turner2017-06-071-1/+1
| | | | | | | | | | | | This creates a new library called BinaryFormat that has all of the headers from llvm/Support containing structure and layout definitions for various types of binary formats like dwarf, coff, elf, etc as well as the code for identifying a file from its magic.

* Rename VMCore directory to IR.Chandler Carruth2013-01-021-0/+22
Aside from moving the actual files, this patch only updates the build system and the source file comments under lib/... that are relevant. I'll be updating other docs and other files in smaller subsequnet commits. While I've tried to test this, but it is entirely possible that there will still be some build system fallout. Also, note that I've not changed the library name itself: libLLVMCore.a is still the library name. I'd be interested in others' opinions about whether we should rename this as well (I think we should, just not sure what it might break) llvm-svn: 171359
