[LLVMdev] question on generating dwarf metadata

Correct: I'm not interested in 'how to use DIFactory', and yes, I do want to
know what the fields of metadata encode in somewhat more detail.
For example, I am struggling with the 'DW_TAG_subroutine_type' now. There is a
field that is labeled:
metadata, ;; Reference to array of member descriptors
Now I figured out that this array contains the types of the formal parameters,
but it also appears the first (and only the first) in the array is the returned
value type of the function. Sinc...

As you can see metadata definition !0 doesn't match documentation.
What is the correct definition (CLANG or LLVM documentation ?).

Don't do that. I know it looks right, but it's broken in DIFactory.

I use the file here, not the compile unit... But again, I could be wrong.
Hope that puts you in the right direction.

While this is great news, it doesn't completely satisfy my needs. Your
documentation assumes one is going to use the LLVM provided functions
(such as DIFactory::). My front-end can't use them because it is not

[LLVMdev] Generating DWARF information that pretends an outparam is the return value
The Rust compiler defines all functions as returning void, with the
first parameter being an outparam of the declared return type, ie.
fn foo2() -> int { ret 5; }
becomes
define void @_ZN4foo217_5cb557d30658848cE(i64*, { i64, { %tydesc*, i1,
{} } }*) uwtable {
store i64 5, i64* %0
ret void
}
I'm working on generating debug information for Rust, and I'm
currently stumped on how
