| # LLVM codegen |
| |
| When Rust calls an LLVM `DIBuilder` function, LLVM translates the given information to a |
| ["debug record"][dbg_record] that is format-agnostic. |
| These records can be inspected in the LLVM-IR. |
| |
| [dbg_record]: https://llvm.org/docs/SourceLevelDebugging.html#debug-records |
| |
| It is important to note that tags within the debug records are **always stored as DWARF tags**. If |
| the target calls for PDB debug info, during codegen the debug records will then be passed through |
| [a module that translates the DWARF tags to their CodeView counterparts][cv]. |
