2021-08-27Remove `Session.if_let_suggestions`Aaron Hill-4/+0
We can instead if either the LHS or RHS types contain `TyKind::Error`. In addition to covering the case where we would have previously updated `if_let_suggestions`, this might also prevent redundant errors in other cases as well.

2021-08-25Rollup merge of #88218 - Aaron1011:missing-method-dyn, r=nagisaLéo Lanteri Thauvin-4/+0
Remove `Session.trait_methods_not_found` Instead, avoid registering the problematic well-formed obligation to begin with. This removes global untracked mutable state, and avoids potential issues with incremental compilation.

2021-08-24Auto merge of #87739 - Aaron1011:remove-used-attrs, r=wesleywiserbors-33/+5
Remove `Session.used_attrs` and move logic to `CheckAttrVisitor` Instead of updating global state to mark attributes as used, we now explicitly emit a warning when an attribute is used in an unsupported position. As a side effect, we are to emit more detailed warning messages (instead of just a generic "unused" message). `Session.check_name` is removed, since its only purpose was to mark the attribute as used. All of the callers are modified to use `Attribute.has_name` Additionally, `AttributeType::AssumedUsed` is removed - an 'assumed used' attribute is implemented by simply not performing any checks in `CheckAttrVisitor` for a particular attribute. We no longer emit unused attribute warnings for the `#[rustc_dummy]` attribute - it's an internal attribute used for tests, so it doesn't mark sense to treat it as 'unused'. With this commit, a large source of global untracked state is removed.

2021-08-15Include (potentially remapped) working dir in crate hashAaron Hill-14/+22
Fixes #85019 A `SourceFile` created during compilation may have a relative path (e.g. if rustc itself is invoked with a relative path). When we write out crate metadata, we convert all relative paths to absolute paths using the current working direction. However, the working directory is not included in the crate hash. This means that the crate metadata can change while the crate hash remains the same. Among other problems, this can cause a fingerprint mismatch ICE, since incremental compilation uses the crate metadata hash to determine if a foreign query is green. This commit moves the field holding the working directory from `Session` to `Options`, including it as part of the crate hash.

Plugin interface cleanup The first commit performs two uncontroversial cleanups. The second commit removes `#[plugin_registrar]` and instead requires you to export a `__rustc_plugin_registrar` function, this will require a change to servo's script_plugins (cc `@jdm)`

2021-08-07Rollup merge of #87761 - rusticstuff:rustc_error_overflow, r=Mark-SimulacrumYuki Okushi-2/+1
Fix overflow in rustc happening if the `err_count()` is reduced in a stage. This can happen if stashed diagnostics are removed or replaced with fewer errors. The semantics stay the same if built without overflow checks. Fixes #84219. Background: I came across this independently by running `RUSTFLAGS="-C overflow-checks=on" ./x.py test`. Fixing this will allow us to move on and find further overflow errors with testing or fuzzing.

2021-07-27Rollup merge of #86450 - tmiasko:move-size-limit, r=pnkfelixYuki Okushi-0/+2
Add flag to configure `large_assignments` lint The `large_assignments` lints detects moves over specified limit. The limit is configured through `move_size_limit = "N"` attribute placed at the root of a crate. When attribute is absent, the lint is disabled. Make it possible to enable the lint without making any changes to the source code, through a new flag `-Zmove-size-limit=N`. For example, to detect moves exceeding 1023 bytes in a cargo crate, including all dependencies one could use: ``` $ env RUSTFLAGS=-Zmove-size-limit=1024 cargo build -vv ``` Lint tracking issue #83518.

Remove unstable `--pretty` flag It doesn't do anything `--unpretty` doesn't, and due to a bug, also didn't show up in `--help`. I don't think there's any reason to keep it around, I haven't seen anyone using it. Closes https://github.com/rust-lang/rust/issues/36473.

Profile incremental compilation hashing fingerprints Adds profiling instrumentation for the hashing of incremental compilation fingerprints per query. This will eventually feed into the `measureme` and `rustc-perf` infrastructure for tracking if computing hashes changes over time. TODOs: * [x] Address the FIXME where we are including node interning in the hash timing. * [ ] Update measureme/summarize to handle this new data: https://github.com/rust-lang/measureme/pull/166 * [ ] ~Update rustc-perf to handle the new data from measureme~ (will be done at a later time) r? `@ghost` cc `@michaelwoerister`

target abi Implement cfg(target_abi) (RFC 2992) Add an `abi` field to `TargetOptions`, defaulting to "". Support using `cfg(target_abi = "...")` for conditional compilation on that field. Gated by `feature(cfg_target_abi)`. Add a test for `target_abi`, and a test for the feature gate. Add `target_abi` to tidy as a platform-specific cfg. Update targets to use `target_abi` All eabi targets have `target_abi = "eabi".` All eabihf targets have `target_abi = "eabihf"`. `armv6_unknown_freebsd` and `armv7_unknown_freebsd` have `target_abi = "eabihf"`. All abi64 targets have `target_abi = "abi64"`. All ilp32 targets have `target_abi = "ilp32"`. All softfloat targets have `target_abi = "softfloat"`. All *-uwp-windows-* targets have `target_abi = "uwp"`. All spe targets have `target_abi = "spe"`. All macabi targets have `target_abi = "macabi"`. aarch64-apple-ios-sim has `target_abi = "sim"`. `x86_64-fortanix-unknown-sgx` has `target_abi = "fortanix"`. `x86_64-unknown-linux-gnux32` has `target_abi = "x32"`. Add FIXME entries for targets for which existing values need to change once `cfg_target_abi` becomes stable. (All of them are tier 3 targets.) Add a test for `target_abi` in `--print cfg`.

add `track_path::path` fn for usage in `proc_macro`s Adds a way to declare a dependency on external files without including them, to either re-trigger the build of a file as well as covering the use case of including dependencies within the `rustc` invocation, such that tools like `sccache`/`cachepot` are able to handle references to external files which are not included.
