2024-08-12[dwarf2yaml] Correctly emit type and split unit headers (#102471)Pavel Labath1-2/+18
(DWARFv5) split units have an extra `dwo_id` field in the header. Type units have `type_signature` and `type_offset`.
2024-02-12[DWARFYAML] Implement debug_names support (#79666)Felipe de Azevedo Piovezan1-0/+29
This commit brings support for debug_names in DWARFYAML. It parses YAML and generates emits a DWARF5 Accelerator table with the following limitations: 1. All forms must have a fixed length (zero length is also ok). 2. Hard-coded support for DWARF 5 and DWARF32. 3. The generated table does not contain a hash index All of these limitations can be lifted in the future, but for now this is good enough to enable testing.
2023-03-13[ADT][NFCI] Do not use non-const lvalue-refs with enumerate in llvm/Jakub Kuderski1-7/+5
Replace references to `enumerate` results with either const lvalue rerences or structured bindings. I did not use structured bindings everywhere as it wasn't clear to me it would improve readability. This is in preparation to the switch to `zip` semantics which won't support non-const lvalue reference to elements: https://reviews.llvm.org/D144503.

2020-10-20Reland "[yaml2obj][ELF] - Simplify the code that performs sections validation."Georgii Rymar1-2/+2
This reverts commit 1b589f4d4db27e3fcd81fdc5abeb9407753ab790 and relands the D89463 with the fix: update `MappingTraits<FileFilter>::validate()` in ClangTidyOptions.cpp to match the new signature (change the return type to "std::string" from "StringRef"). Original commit message: This: Changes the return type of MappingTraits<T>>::validate to std::string instead of StringRef. It allows to create more complex error messages. It introduces std::vector<std::pair<StringRef, bool>> getEntries(): a new virtual method of Section, which is the base class for all sections. It returns names of special section specific keys (e.g. "Entries") and flags that says if them exist in a YAML. The code in validate() uses this list of entries descriptions to generalize validation. This approach was discussed in the D89039 thread. Differential revision: https://reviews.llvm.org/D89463
