Description

llvm::joinErrors

Concatenate errors. The resulting Error is unchecked, and contains the ErrorInfo(s), if any, contained in E1, followed by the ErrorInfo(s), if any, contained in E2.

llvm::visitErrors

Visit all the ErrorInfo(s) contained in E by passing them to the respective handler, without consuming the error.

llvm::handleErrors

Pass the ErrorInfo(s) contained in E to their respective handlers. Any unhandled errors (or Errors returned by handlers) are re‐concatenated and returned. Because this function returns an error, its result must also be checked or returned. If you intend to handle all errors use handleAllErrors (which returns void, and will abort() on unhandled errors) instead.
