2019-09-16[Remarks] Allow remarks::Format::YAML to take a string tableFrancis Visoiu Mistrih1-1/+0
It should be allowed to take a string table in case all the strings in the remarks point there, but it shouldn't use it during serialization. llvm-svn: 372042
2019-09-06[Remarks] Add support for internalizing a remark in a string tableFrancis Visoiu Mistrih1-0/+17
In order to keep remarks around, we need to make them tied to a string table. Users then can delete the parser and rely on the string table to keep the memory of the strings alive and deduplicated. llvm-svn: 371233
2019-07-23[Remarks] String tables should be move-onlyFrancis Visoiu Mistrih1-0/+9
Copying them is expensive. This allows the tables to be moved around at lower cost, and allows a remarks::StringTable to be constructed from a remarks::ParsedStringTable. llvm-svn: 366864
2019-07-23[Remarks] Add unit tests for YAML serializationFrancis Visoiu Mistrih1-3/+0
Add tests for both the string table and non string table case. llvm-svn: 366832
2019-04-24[Remarks] Add string deduplication using a string tableFrancis Visoiu Mistrih1-0/+48
* 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.
