2023-05-19Auto merge of #111641 - michaelwoerister:debugger-visualizer-fixes, r=cjgillotbors-2/+1
Fix dependency tracking for debugger visualizers This PR fixes dependency tracking for debugger visualizer files by changing the `debugger_visualizers` query to an `eval_always` query that scans the AST while it is still available. This way the set of visualizer files is already available when dep-info is emitted. Since the query is turned into an `eval_always` query, dependency tracking will now reliably detect changes to the visualizer script files themselves.

Only depend on CFG_VERSION in rustc_interface This avoids having to rebuild the whole compiler on each commit when `omit-git-hash = false`. cc https://github.com/rust-lang/rust/issues/76720 - this won't fix it, and I'm not suggesting we turn this on by default, but it will make it less painful for people who do have `omit-git-hash` on as a workaround.

2023-05-03debuginfo: split method declaration and definitionJosh Stone-34/+51
When we're adding a method to a type DIE, we only want a DW_AT_declaration there, because LLVM LTO can't unify type definitions when a child DIE is a full subprogram definition. Now the subprogram definition gets added at the CU level with a specification link back to the abstract declaration.

2023-04-18Auto merge of #110083 - saethlin:encode-hashes-as-bytes, r=cjgillotbors-1/+2
Encode hashes as bytes, not varint In a few places, we store hashes as `u64` or `u128` and then apply `derive(Decodable, Encodable)` to the enclosing struct/enum. It is more efficient to encode hashes directly than try to apply some varint encoding. This PR adds two new types `Hash64` and `Hash128` which are produced by `StableHasher` and replace every use of storing a `u64` or `u128` that represents a hash. Distribution of the byte lengths of leb128 encodings, from `x build --stage 2` with `incremental = true` Before: ``` ( 1) 373418203 (53.7%, 53.7%): 1 ( 2) 196240113 (28.2%, 81.9%): 3 ( 3) 108157958 (15.6%, 97.5%): 2 ( 4) 17213120 ( 2.5%, 99.9%): 4 ( 5) 223614 ( 0.0%,100.0%): 9 ( 6) 216262 ( 0.0%,100.0%): 10 ( 7) 15447 ( 0.0%,100.0%): 5 ( 8) 3633 ( 0.0%,100.0%): 19 ( 9) 3030 ( 0.0%,100.0%): 8 ( 10) 1167 ( 0.0%,100.0%): 18 ( 11) 1032 ( 0.0%,100.0%): 7 ( 12) 1003 ( 0.0%,100.0%): 6 ( 13) 10 ( 0.0%,100.0%): 16 ( 14) 10 ( 0.0%,100.0%): 17 ( 15) 5 ( 0.0%,100.0%): 12 ( 16) 4 ( 0.0%,100.0%): 14 ``` After: ``` ( 1) 372939136 (53.7%, 53.7%): 1 ( 2) 196240140 (28.3%, 82.0%): 3 ( 3) 108014969 (15.6%, 97.5%): 2 ( 4) 17192375 ( 2.5%,100.0%): 4 ( 5) 435 ( 0.0%,100.0%): 5 ( 6) 83 ( 0.0%,100.0%): 18 ( 7) 79 ( 0.0%,100.0%): 10 ( 8) 50 ( 0.0%,100.0%): 9 ( 9) 6 ( 0.0%,100.0%): 19 ``` The remaining 9 or 10 and 18 or 19 are `u64` and `u128` respectively that have the high bits set. As far as I can tell these are coming primarily from `SwitchTargets`.

2023-04-04Auto merge of #109808 - jyn514:debuginfo-options, r=michaelwoeristerbors-19/+2
Extend -Cdebuginfo with new options and named aliases This is a rebase of https://github.com/rust-lang/rust/pull/83947, along with my best guess at what the new options mean. I tried to follow the LLVM source code to get a better idea but ran into quite a lot of trouble (https://rust-lang.zulipchat.com/#narrow/stream/187780-t-compiler.2Fwg-llvm/topic/go-to-definition.20in.20src.2Fllvm-project.3F). The description for the original PR follows below. Note that the changes in this PR have already been through FCP: https://github.com/rust-lang/rust/pull/83947#issuecomment-878384979 Closes https://github.com/rust-lang/rust/pull/109311. Helps with https://github.com/rust-lang/rust/pull/104968. r? `@michaelwoerister` cc `@cuviper` --- The -Cdebuginfo=1 option was never line tables only and can't be due to backwards compatibility issues. This was clarified and an option for emitting line tables only was added. Additionally an option for emitting line info directives only was added, which is needed for some targets, i.e. nvptx. The debug info options should now behave similarly to clang's debug info options. Fix https://github.com/rust-lang/rust/issues/60020 Fix https://github.com/rust-lang/rust/issues/64405

2023-04-02Use `&IndexSlice` instead of `&IndexVec` where possibleScott McMurray-2/+2
All the same reasons as for `[T]`: more general, less pointer chasing, and `&mut IndexSlice` emphasizes that it doesn't change *length*.
2023-03-31Preserve, clarify, and extend debug informationJulia Tatz-19/+2
`-Cdebuginfo=1` was never line tables only and can't be due to backwards compatibility issues. This was clarified and an option for line tables only was added. Additionally an option for line info directives only was added, which is well needed for some targets. The debug info options should now behave the same as clang's debug info options.
2023-03-30Update `ty::VariantDef` to use `IndexVec<FieldIdx, FieldDef>`Scott McMurray-1/+2
And while doing the updates for that, also uses `FieldIdx` in `ProjectionKind::Field` and `TypeckResults::field_indices`. There's more places that could use it (like `rustc_const_eval` and `LayoutS`), but I tried to keep this PR from exploding to *even more* places.

2023-03-28Move `mir::Field` → `abi::FieldIdx`Scott McMurray-3/+5
The first PR for https://github.com/rust-lang/compiler-team/issues/606 This is just the move-and-rename, because it's plenty big-and-bitrotty already. Future PRs will start using `FieldIdx` more broadly, and concomitantly removing `FieldIdx::new`s.

...and remove it from `PointeeInfo`, which isn't meant for this. There are still various places (marked with FIXMEs) that assume all pointers have the same size and alignment. Fixing this requires parsing non-default address spaces in the data layout string, which will be done in a followup.

Pass 128-bit C-style enum enumerator values to LLVM Pass the full 128 bits of C-style enum enumerators through to LLVM. This means that debuginfo for C-style repr128 enums is now emitted correctly for DWARF platforms (as compared to not being correctly emitted on any platform). Tracking issue: #56071
