2022-05-03Auto merge of #96601 - tmiasko:ssa-rpo, r=davidtwcobors-2/+2
Use reverse postorder in `non_ssa_locals` The reverse postorder, unlike preorder, is now cached inside the MIR body. Code generation uses reverse postorder anyway, so it might be a small perf improvement to use it here as well.
2022-05-03Rollup merge of #96587 - bjorn3:refactor_backend_write, r=michaelwoeristerYuki Okushi-30/+15
Refactor the WriteBackendMethods and ExtraBackendMethods traits The new interface is slightly less confusing and is easier to implement for non-LLVM backends.

Reduce duplication of RPO calculation of mir Computing the RPO of mir is not a low-cost thing, but it is duplicate in many places. In particular the `iterate_to_fixpoint` method which is called multiple times when computing the data flow. This PR reduces the number of times the RPO is recalculated as much as possible, which should save some compile time.

not need `Option` for `dbg_scope` This PR fixes a few FIXME about not using `Option` in `dbg_scope` field of `DebugScope`, during `create_function_debug_context` func in codegen parts. Added a `BitSet<SourceScope>` parameter to `make_mir_scope` to indicate whether the `DebugScope` has been instantiated. cc ````@eddyb````

Generate synthetic object file to ensure all exported and used symbols participate in the linking Fix #50007 and #47384 This is the synthetic object file approach that I described in https://github.com/rust-lang/rust/pull/95363#issuecomment-1079932354, allowing all exported and used symbols to be linked while still allowing them to be GCed.

Stop using CRATE_DEF_INDEX outside of metadata encoding. `CRATE_DEF_ID` and `CrateNum::as_def_id` are almost always what we want. We should not manipulate raw `DefIndex` outside of metadata encoding.

Let CTFE to handle partially uninitialized unions without marking the entire value as uninitialized. follow up to #94411 To fix https://github.com/rust-lang/rust/issues/69488 and by extension fix https://github.com/rust-lang/rust/issues/94371, we should stop treating types like `MaybeUninit<usize>` as something that the `Scalar` type in the interpreter engine can represent. So we add a new field to `abi::Primitive` that records whether the primitive is nested in a union cc `@RalfJung` r? `@ghost`

2022-04-05errors: implement fallback diagnostic translationDavid Wood-5/+15
This commit updates the signatures of all diagnostic functions to accept types that can be converted into a `DiagnosticMessage`. This enables existing diagnostic calls to continue to work as before and Fluent identifiers to be provided. The `SessionDiagnostic` derive just generates normal diagnostic calls, so these APIs had to be modified to accept Fluent identifiers. In addition, loading of the "fallback" Fluent bundle, which contains the built-in English messages, has been implemented. Each diagnostic now has "arguments" which correspond to variables in the Fluent messages (necessary to render a Fluent message) but no API for adding arguments has been added yet. Therefore, diagnostics (that do not require interpolation) can be converted to use Fluent identifiers and will be output as before.
2022-04-05errors: introduce `DiagnosticMessage`David Wood-2/+2
Introduce a `DiagnosticMessage` type that will enable diagnostic messages to be simple strings or Fluent identifiers. `DiagnosticMessage` is now used in the implementation of the standard `DiagnosticBuilder` APIs. Signed-off-by: David Wood <david.wood@huawei.com>
