If all subcandidates have never-pattern, the parent candidate should have otherwise_block because some methods expect the candidate has the block. Signed-off-by: Shunpoco <tkngsnsk313320@gmail.com>
If all subcandidates have never-pattern, we should assign false_edge_start_block to the parent candidate if it doesn't have. merge_trivial_subcandidates does so, but if the candidate has guard it returns before the assignment. Signed-off-by: Shunpoco <tkngsnsk313320@gmail.com>

When a struct definition has default field values, and the use struct ctor has missing field, if all those missing fields have defaults suggest `..`:
```

When we attempt to load a Rust source code file, if there is a OS file failure we try reading the file as bytes. If that succeeds we try to turn it into UTF-8. If *that* fails, we provide additional context about *where* the file has the first invalid UTF-8 character.
Fix rust-lang#76869.
Use enum Void to avoid mistmatched types error Signed-off-by: Shunpoco <tkngsnsk313320@gmail.com>
- Use enum Void to avoid mismatched types error - We don't need to use if let to check the ICE Signed-off-by: Shunpoco <tkngsnsk313320@gmail.com>
The candidate shouldn't have false_edge_start_block if it has sub candidates. In remove_never_subcandidates(), the false_edge_start_block from the first sub candidte is assigned to a value and the value is later used if all sub candidates are removed and candidate doesn't have false_edge_start_block. In merge_trivial_subcandidates, I leave the if block which assign a false_edge_start_block into the candidate as before I put this commit since compile panics.

…lse-edge-start-block, r=Nadrieril Fix ICE-133117: multiple never-pattern arm doesn't have false_edge_start_block Fixes rust-lang#133117 , and close fixes rust-lang#133063 , fixes rust-lang#130779 In order to fix ICE-133117, at first I needed to tackle to ICE-133063 (this fixed 130779 as well). ### ICE-133063 and ICE-130779 This ICE is caused by those steps: 1. An arm has or-pattern, and all of the sub-candidates are never-pattern 2. In that case, all sub-candidates are removed in remove_never_subcandidates(). So the arm (candidate) has no sub-candidate. 3. In the current implementation, if there is no sub-candidate, the function assigns `pre_binding_block` into the candidate ([here](https://github.com/rust-lang/rust/blob/master/compiler/rustc_mir_build/src/builder/matches/mod.rs#L2002-L2004)). However, otherwise_block should be assigned to the candidate as well, because the otherwise_block is unwrapped in multiple place (like in lower_match_tree()). As a result, it causes the panic. I simply added the same block as pre_binding_block into otherwise_block, but I'm wondering if there is a better block to assign to otherwise_block (is it ok to assign the same block into pre_binding and otherwise?) ### ICE-133117 This is caused by those steps: 1. There are two arms, both are or-pattern and each has one match-pair (in the test code, both are `(!|!)`), and the second arm has a guard. 2. In match_candidate() for the first arm, it expands the second arm’s sub-candidates as well ([here](https://github.com/rust-lang/rust/blob/master/compiler/rustc_mir_build/src/builder/matches/mod.rs#L1800-L1805)). As a result, the root candidate of the second arm is not evaluated/modified in match_candidate(). So a false_edge_start_block is not assigned to the candidate. 3. merge_trivial_subcandidates() is called against the candidate for the second arm. It just returns immediately because the candidate has a guard. So a flase_edge_start_block is not assigned to the candidate also in this function. 4. remove_never_subcandidates() is called against the candidate. Since all sub-candidates are never-pattern. they are removed. 5. In lower_match_tree(), since there is no sub-candidate for the candidate, the candidate itself is evaluated in visit_leave_rev ([here](https://github.com/rust-lang/rust/blob/master/compiler/rustc_mir_build/src/builder/matches/mod.rs#L1532)). Because the candidate has no false_edge_start_block, it causes the panic. So I modified the order of if blocks in merge_trivial_subcandidates() to assign a false_edge_start_block if the candidate doesn't have.

Properly note when query stack is being cut off cc rust-lang#70953 also, i'm not certain whether we should even limit this at all. i don't see the problem with printing the full query stack, apparently it was limited b/c we used to ICE? but we're already printing the full stack to disk since rust-lang#108714. r? oli-obk

Detect missing fields with default values and suggest `..`
When a struct ctor use has missing fields, if all those missing fields have defaults, suggest `..`:

…rochenkov Misc. `rustc_resolve` cleanups Hopefully this PR should make `rustc_resolve` a bit cleaner. Each commit here stands on its own. I tried to only include changes that are easy to review, and are a clear improvement. (but I'll be happy to revert any changes that turn out to be more controversial than I'd thought) Best viewed with whitespace ignored 😁 (especially [these two commits](https://github.com/rust-lang/rust/pull/135826/files/a93616acf3118ef233027d74e8c636f9b79c342d..ae87d005bc92cbecc47b554e634d1bd3d22e1068?diff=unified&w=1))
