Hi. I searched and the closest thing I could find was this http://lists.llvm.org/pipermail/llvm-dev/2018-February/121348.html Currently a known sized array looks and debugs as expected. I use llvm.dbg.declare with DICompositeType tag: DW_TAG_array_type and the size field. In my language arrays are always passed around with a pointer and size pair. I'd like debugging to show up as nicely instead of a pointer addr with no information about the elements. How would I do this? I don't use the C API, I output llvm-ir directly. I was hoping I ca...

Hi, I see things like this. What does it mean? Is it documented somewhere?

In r219010, I merged integer and string fields into a single header field. By reducing the number of metadata operands used in debug info, this saved 2.2GB on an `llvm-lto` bootstrap. I've done some profiling of DW_TAGs to see what parts of PR17891 and PR17892 to tackle next, and I've concluded that they will be insufficient. Instead, I'd like to implement a more aggressive plan,
