The diagnostics/error reporting API is a mess. It should:

  • Be independent of logging
  • Support error/warn/notice/info levels
  • Be aware of source location (only one level is necessary; related messages can follow)
  • Support error codes for each type of problem (likely reuse i18n infrastructure for this, see Logging infrastructure #11)
  • Propagate through all stages in such a way that:
    • C probes may correspond to original source file/line in such a way that C probe errors may be relayed into the main diagnostic context
    • Backend compilation errors correspond to original source whenever possible
  • Employ (or at least examine) best practices established by long-lived existent static compilers such as gcc, clang as well as modern languages like rust, go etc.
  • Take advantage of diagnostic location information on nodes (?)

This piece is fundamental enough that an informal design proposal should be the first deliverable.
