src/tools/compiletest/src/runtest.rs

-        if !path.exists() && self.config.compare_mode.is_some() {
-            // fallback!
+
+        if !path.exists() {


Hmm, this is a bit more hard-coded than I expected, but I imagine it does the right thing.

Maybe it's not worth making a super general mechanism here, given that we'll hopefully be removing polonius and nll "soon".

What I expected was some kind of table where, for each compare-mode, we specify a "parent" mode (which may be None for nll) — and we iterate through modes, walking to their parents (and ultimately to a None mode) — looking for a path that exists.

src/bootstrap/test.rs

+        if let Some(compare_mode) = builder.config.cmd.compare_mode() {
+            cmd.arg("--compare-mode").arg(compare_mode);
+        }
+


There appears to be some very similar logic a few lines below:

https://github.com/spastorino/rust/blob/fb2a51225f26f8acf39e482d916f112265c81d35/src/bootstrap/test.rs#L1136-L1143

It seems like there is a compare_mode that comes from the test directory configuration as well as one (now) that you have added to builder.config.cmd. Perhaps we want to just change this line to something like this:

let compare_mode = builder.config.cmd.compare_mode().or(self.compare_mode);

(This is giving precedence to the --compare-mode option from the command line, which seems appropriate.)

(Alternatively, we could error if compare-mode is given both in the command line and the test suite definition; I think that the latter (test suite) can only occur when running ./x.py test, in which case the command line probably ought not to be in use.)
