Even without the psoc6 errors, we get an error with earlgrey: It seems like maybe this is caused where there are "too many" registers defined in the registers struct macro. @lschuermann @hudson-ayers Do you know what changed in Rust? Are we supposed to fix something about the registers macro, have smaller registers mapping, or follow the guidance of the compiler error? Is there a reason we would do this piecemeal (ie set it for individual crates) versus somehow change the setting for the entire workspace? It would be nice if Rust provided some sort of pointer to info about this change if something that wasn't an error before suddenly becomes an error. |

Well, this used to be an issue before, and it just seems that some compiler internals have either changed the default recursion limits, or how many iterations the compiler spends / "thinks it spends" trying to expand this macro. Hence, I think this is effectively just this: #2941 (comment) tl;dr: we have a small PoC on how to make this better, but we're still fundamentally recursive and wouldn't solve this issue for good. To me it still seems most promising to pursue #4001, which will completely supersede and deprecate this infrastructure, and not suffer from the same macro-rules restrictions and issues. |
This is needed for large register definitions.
