Research direction

Start by locating the textual format emitted by regalloc2-tool and reviewing how creduce consumes inputs. Determine the changes needed for the output to be sufficiently C-like, then verify that a script can use creduce to minimize a failing regalloc2 input.

Written by the indexing model from the issue text.

Description

The fuzzing strategy we use for regalloc2 doesn't minimize well, which can make isolating a failure somewhat tedious. If the textual format emitted by regalloc2-tool looked enough like c to be used with creduce, we could write a script to automate minimization by using creduce to shrink the input.
