[Lldb-commits] [PATCH] D87878: [DWARFYAML] Make the include_directories, file_names and opcodes fields of the line table optional.

2020-09-18 Thread James Henderson via Phabricator via lldb-commits

jhenderson added a comment.

I might be missing it, but do you have direct testing showing that the default 
for `IncludeDirs`\`Files`\`Opcodes` is an empty output, when the output is 
written? I think it's important that this is tested.

Sorry, I didn't test it.

Add test case (k) in llvm/test/tools/yaml2obj/ELF/DWARF/debug-line.yaml.

[Lldb-commits] [PATCH] D85705: Add a "Trace" plug-in to LLDB to add process trace support in stages.

2020-09-18 Thread walter erquinigo via Phabricator via lldb-commits

wallace updated this revision to Diff 292922.
wallace added a comment.

Based on the discussion from D87335 , I'm 
moving all the JSON utilities as non-member functions to the settings parser 
file. Eventually this can be refactored if that patch moves forward.

There aren't any other pending issues.
