this sure is getting to be an exciting test file
There was a problem hiding this comment.
in the interest of minimizing (not eliminating, only minimizing) conflicts with a number of other in-flight PRs touching this file, can you duplicate (yes, duplicate as in add-a-new-file-with, not first-remove-here-and-then-add-a-new-file-with) the parts of the test for interrupt ABIs that you want to edit? then revert the change to this file that aren't going-to-happen-anyway?
include a FIXME that the duplication is intentional in the new file and that in the near future the duplication should be reduced (preferably by splitting up unsupported.rs a bit more but it really doesn't matter).

| functions with the `{$abi}` ABI cannot be called |

same idea as the style nits on other PR
| functions with the `{$abi}` ABI cannot be called | |
| functions with the {$abi} ABI cannot be called |

We recently added
extern "custom", which cannot be called using a rust call expression. But there are more ABIs that can't be called in that way, because the call does not semantically make sense.More details are in #140566 (comment)
