2023-02-02Revert back to LlvmArchiveBuilder on all platformsbjorn3-1/+3
ArArchiveBuilder doesn't support reading thin archives, causing a regression.

2022-12-27Switch `#[track_caller]` back to a no-op unless feature gate is enabledBryan Garza-11/+83
This patch fixes a regression, in which `#[track_caller]`, which was previously a no-op, was changed to actually turn on the behavior. This should instead only happen behind the `closure_track_caller` feature gate. Also, add a warning for the user to understand how their code will compile depending on the feature gate being turned on or not. Fixes #104588

2022-12-26Mangle "main" as "__main_void" on wasm32-wasiDan Gohman-0/+4
On wasm, the age-old C trick of having a main function which can either have no arguments or argc+argv doesn't work, because wasm requires caller and callee signatures to match. WASI's current strategy is to have compilers mangle main's name to indicate which signature they're using. Rust uses the no-argument form, which should be mangled as `__main_void`. This is needed on wasm32-wasi as of #105395.

2022-12-09Rollup merge of #105455 - lcnr:correct-reveal-in-validate, r=jackh726Matthias Krüger-1/+13
use the correct `Reveal` during validation supersedes #105454. Deals with https://github.com/rust-lang/rust/issues/105009#issuecomment-1342395333, not closing #105009 as the ICE may leak into beta The issue was the following: - we optimize the mir, using `Reveal::All` - some optimization relies on the hidden type of an opaque type - we then validate using `Reveal::UserFacing` again which is not able to observe the hidden type r? `@jackh726`

2022-12-08Rollup merge of #105405 - sunfishcode:sunfishcode/export-dynamic, r=TaKO8KiMatthias Krüger-7/+0
Stop passing -export-dynamic to wasm-ld. -export-dynamic was a temporary hack added in the early days of the Rust wasm32 target when Rust didn't have a way to specify wasm exports in the source code. This flag causes all global symbols, and some compiler-internal symbols, to be exported, which is often more than needed. Rust now does have a way to specify exports in the source code: `#[export_name = "..."]`. So as the original comment suggests, -export-dynamic can now be removed, allowing users to have smaller binaries and better encapsulation in their wasm32-unknown-unknown modules. It's possible that this change will require existing wasm32-unknown-unknown users will to add explicit `#[export_name = "..."]` directives to exporrt the symbols that their programs depend on having exported.
2022-12-08Rollup merge of #105317 - RalfJung:retag-rework, r=oli-obkMatthias Krüger-67/+63
make retagging work even with 'unstable' places This is based on top of https://github.com/rust-lang/rust/pull/105301. Only the last two commits are new. While investigating https://github.com/rust-lang/unsafe-code-guidelines/issues/381 I realized that we would have caught this issue much earlier if the add_retag pass wouldn't bail out on assignments of the form `*ptr = ...`. So this PR changes our retag strategy: - When a new reference is created via `Rvalue::Ref` (or a raw ptr via `Rvalue::AddressOf`), we do the retagging as part of just executing that address-taking operation. - For everything else, we still insert retags -- these retags basically serve to ensure that references stored in local variables (and their fields) are always freshly tagged, so skipping this for assignments like `*ptr = ...` is less egregious. r? ```@oli-obk```

2022-12-07Rollup merge of #105400 - BoxyUwU:braced_param_evaluatability, r=oli-obkMatthias Krüger-1/+1
normalize before handling simple checks for evaluatability of `ty::Const` `{{{{{{{ N }}}}}}}` is desugared into a `ConstKind::Unevaluated` for an anonymous `const` item so when calling `is_const_evaluatable` on it we skip the `ConstKind::Param(_) => Ok(())` arm which is incorrect.

2022-12-07Rollup merge of #105343 - nbdd0121:hir, r=fee1-deadMatthias Krüger-106/+45
Simplify attribute handling in rustc_ast_lowering Given that attributes is stored in a separate BTreeMap, it's not necessary to pass it in when constructing `hir::Expr`. We can just construct `hir::Expr` and then call `self.lower_attrs` later if it needs attributes. As most desugaring code don't use attributes, this allows some code cleanup.

2022-12-07Auto merge of #105291 - nnethercote:remove-LintPassObjects, r=cjgillotbors-100/+51
Remove `{Early,Late}LintPassObjects`. `EarlyContextAndPass` wraps a single early lint pass. We aggregate multiple passes into that single pass by using `EarlyLintPassObjects`. This commit removes `EarlyLintPassObjects` by changing `EarlyContextAndPass` into `EarlyContextAndPasses`. I.e. it just removes a level of indirection. This makes the code simpler and slightly faster. The commit does likewise for late lints. r? `@cjgillot`
