2ede126b - DebugInfo: preparation to implement DW_AT_alignment

Thu, 20 Oct 2016 00:13:12 +0000

DebugInfo: preparation to implement DW_AT_alignment - Add alignment attribute to DIVariable family - Modify bitcode format to match new DIVariable representation - Update tests to match these changes (also add bitcode upgrade test) - Expect that frontend passes non-zero align value only when it is not default (was forcibly aligned by alignas()/_Alignas()/__atribute__(aligned())Differential Revision: https://reviews.llvm.org/D25073llvm-svn: 284678 List of files: /llvm-project-15.0.7/llvm/test/Assembler/dilocalvariable.ll

75819aed - [PR27284] Reverse the ownership between DICompileUnit and DISubprogram.

Fri, 15 Apr 2016 15:57:41 +0000

[PR27284] Reverse the ownership between DICompileUnit and DISubprogram.Currently each Function points to a DISubprogram and DISubprogram has ascope field. For member functions the scope is a DICompositeType. DIScopespoint to the DICompileUnit to facilitate type uniquing.Distinct DISubprograms (with isDefinition: true) are not part of the typehierarchy and cannot be uniqued. This change removes the subprogramslist from DICompileUnit and instead adds a pointer to the owning compileunit to distinct DISubprograms. This would make it easy for ThinLTO tostrip unneeded DISubprograms and their transitively referenced debug info.Motivation----------Materializing DISubprograms is currently the most expensive operation whendoing a ThinLTO build of clang.We want the DISubprogram to be stored in a separate Bitcode block (or thesame block as the function body) so we can avoid having to expensivelydeserialize all DISubprograms together with the global metadata. If afunction has been inlined into another subprogram we need to store areference the block containing the inlined subprogram.Attached to https://llvm.org/bugs/show_bug.cgi?id=27284 is a python scriptthat updates LLVM IR testcases to the new format.http://reviews.llvm.org/D19034llvm-svn: 266446 List of files: /llvm-project-15.0.7/llvm/test/Assembler/dilocalvariable.ll

ed013cd2 - DI: Remove DW_TAG_arg_variable and DW_TAG_auto_variable

Fri, 31 Jul 2015 18:58:39 +0000

DI: Remove DW_TAG_arg_variable and DW_TAG_auto_variableRemove the fake `DW_TAG_auto_variable` and `DW_TAG_arg_variable` tags,using `DW_TAG_variable` in their place Stop exposing the `tag:` field atall in the assembly format for `DILocalVariable`.Most of the testcase updates were generated by the following sed script: find test/ -name "*.ll" -o -name "*.mir" | xargs grep -l 'DILocalVariable' | xargs sed -i '' \ -e 's/tag: DW_TAG_arg_variable, //' \ -e 's/tag: DW_TAG_auto_variable, //'There were only a handful of tests in `test/Assembly` that I needed toupdate by hand.(Note: a follow-up could change `DILocalVariable::DILocalVariable()` toset the tag to `DW_TAG_formal_parameter` instead of `DW_TAG_variable`(as appropriate), instead of having that logic magically in the backendin `DbgVariable`. I've added a FIXME to that effect.)llvm-svn: 243774 List of files: /llvm-project-15.0.7/llvm/test/Assembler/dilocalvariable.ll

56b893b3 - DI/Verifier: Fix argument bitrot in DILocalVariable

Fri, 24 Jul 2015 23:59:25 +0000

DI/Verifier: Fix argument bitrot in DILocalVariableAdd a verifier check that `DILocalVariable`s of tag`DW_TAG_arg_variable` always have a non-zero 'arg:' field, and those oftag `DW_TAG_auto_variable` always have a zero 'arg:' field. These arethe only configurations that are properly understood by the backend.(Also, fix the bad examples in LangRef and test/Assembler, and fix thebug in Kaleidoscope Ch8.)A large number of testcases seem to have bitrotted their way forwardfrom some ancient version of the debug info hierarchy that didn't have`arg:` parameters. If you have out-of-tree testcases that start failingin the verifier and you don't care enough to get the `arg:` right, youmay have some luck just calling: sed -e 's/, arg: 0/, arg: 1/'or some such, but I hand-updated the ones in tree.llvm-svn: 243183 List of files: /llvm-project-15.0.7/llvm/test/Assembler/dilocalvariable.ll
