+;; Test --substitute-path and --source-dir with --source and --line-numbers.
+;;
+;; The object records source paths under /wrong/Inputs, but the source file
+;; lives in this test's Inputs directory. Without path remapping, --source
+;; cannot load the file from disk.
+;;
+;; --source-dir: one directory per flag; later flags on the command line are
+;; searched before earlier ones.
+;;
+;; --substitute-path: rules are tried in command-line order; the first match
+;; wins (same as GDB set substitute-path).

This isn't needed: the X86 directory has it in a lit.local.cfg.
