The name of NativeLib will be presented
Fixes#109144
I was working on a quick fix, but found change the name from `Option<Symbol>` to `Symbol` make life a little bit easier.
Do not implement HashStable for HashSet (MCP 533)
This PR removes all occurrences of `HashSet` in query results, replacing it either with `FxIndexSet` or with `UnordSet`, and then removes the `HashStable` implementation of `HashSet`. This is part of implementing [MCP 533](https://github.com/rust-lang/compiler-team/issues/533), that is, removing the `HashStable` implementations of all collection types with unstable iteration order.
The changes are mostly mechanical. The only place where additional sorting is happening is in Miri's override implementation of the `exported_symbols` query.
rustc_middle: Remove trait `DefIdTree`
This trait was a way to generalize over both `TyCtxt` and `Resolver`, but now `Resolver` has access to `TyCtxt`, so this trait is no longer necessary.
Make compressed rmeta contain compressed data length after header
Fixes#90056, which is caused by link.exe introducing padding to the `.rustc` section, since it assumes this will have no effect besides allowing it to possibly use the extra space in future links.
(This is a large commit. The changes to
`compiler/rustc_middle/src/ty/context.rs` are the most important ones.)
The current naming scheme is a mess, with a mix of `_intern_`, `intern_`
and `mk_` prefixes, with little consistency. In particular, in many
cases it's easy to use an iterator interner when a (preferable) slice
interner is available.
The guiding principles of the new naming system:
- No `_intern_` prefixes.
- The `intern_` prefix is for internal operations.
- The `mk_` prefix is for external operations.
- For cases where there is a slice interner and an iterator interner,
the former is `mk_foo` and the latter is `mk_foo_from_iter`.
Also, `slice_interners!` and `direct_interners!` can now be `pub` or
non-`pub`, which helps enforce the internal/external operations
division.
It's not perfect, but I think it's a clear improvement.
The following lists show everything that was renamed.

The GNU linker accepts -z<params>, but this is undocumented, and
not supported by other linkers.
In particular, `zig cc`, when used as the C compiler/linker
(e.g. when using `cargo-zigbuild`), will not accept this
undocumented syntax.
In `linker.rs`, both syntaxes are also used inconsistently.
The Go compiler used to have the same issue, but fixed it:

Enable new rlib in non stable cases
If bundled static library uses cfg (unstable) or whole-archive (wasn't supported) bundled libs are packed even without packed_bundled_libs.
r? `@petrochenkov`
Append .dwp to the binary filename instead of replacing the existing extension.
gdb et al. expect to find the dwp file at `<binary>`.dwp, even if <binary> already has an extension (e.g. libfoo.so's dwp is expected to be at libfoo.so.dwp).
gdb et al. expect to find the dwp file at <binary>.dwp, even if <binary> already

The optimization that removes artifacts when building libraries is correct
from the compiler's perspective but not from a debugger's perspective.
Unpacked split debuginfo is referred to by filename and debuggers need
the artifact that contains debuginfo to continue to exist at that path.
Ironically the test expects the correct behavior but it was not running.
Fix aarch64-unknown-linux-gnu_ilp32 target
This was broken because the synthetic object files produced by rustc were for 64-bit AArch64, which caused link failures when combined with 32-bit ILP32 object files.
This PR updates the object crate to 0.30.1 which adds support for generating ILP32 AArch64 object files.
riscv: Fix ELF header flags
The previous version added both `EF_RISCV_FLOAT_ABI_DOUBLE` and `EF_RISCV_RVC` if the "D" extension was enabled on riscv64 targets. riscv32 targets were not accounted for. This patch changes this so that:
- Only add `EF_RISCV_RVC` if the "C" extension is enabled
- Add `EF_RISCV_FLOAT_ABI_SINGLE` if the "F" extension is enabled and the "D" extension is not
- Add these ELF flags for riscv32 as well

Linker drivers such as gcc, clang or lld often have a version postfix,
e.g clang-12. The previous logic would not account for this and would
fall back to guessing the linker flavor to be the default linker flavor
for the target, which causes linker errors when this is not the case.
By accounting for the possible version postfix and also considering
g++ and clang++, we considerably reduce the amount of times the
fallback guess has to be used.
To simplify matching check for a version postfix and match against the
linker stem without any version postfix.
In contrast to gcc, clang supports all architectures in one binary.
This means there are no variants like `aarch64-linux-gnu-clang` and
there is no need to check for `-clang` variants.
The previous version added both `EF_RISCV_FLOAT_ABI_DOUBLE` and
`EF_RISCV_RVC` if the "D" extension was enabled on riscv64 targets.
riscv32 targets were not accounted for. This patch changes this
so that:
- Only add `EF_RISCV_RVC` if the "C" extension is enabled
- Add `EF_RISCV_FLOAT_ABI_SINGLE` if the "F" extension is enabled
and the "D" extension is not
- Add these ELF flags for riscv32 as well

Migrate `codegen_ssa` to diagnostics structs - [Part 3]
Completes migrating `codegen_ssa` module except 2 outstanding errors that depend on other crates:
1. [`rustc_middle::mir::interpret::InterpError`](b6097f2e1b/compiler/rustc_middle/src/mir/interpret/error.rs (L475)): I saw `rustc_middle` is unassigned, I am open to take this work.
2. `codegen_llvm`'s use of `fn span_invalid_monomorphization_error`, which I started to replace in the [last commit](9a31b3cdda) of this PR, but would like to know the team's preference on how we should keep replacing the other macros:
2.1. Update macros to expect a `Diagnostic`
2.2. Remove macros and expand the code on each use.
See [some examples of the different options in this experimental commit](64aee83e80)

Small fixes for --crate-type staticlib
The first commit doesn't have an effect until we start translating error messages. The second commit fixes potential linker errors when combining `--crate-type staticlib` with another crate type and I think `-Cprefer-dynamic`.
On macOS, it's not yet clear which cases of clang/OS/target/SDK version impact
how to find ld/lld/rust-lld. The --target is not needed on our current targets with
a vanilla config, but may be in some cases. Specifying it all the time breaks the 10.7+
targets on x64 macOS.
We try to only specify it on macOS if the linker flavors are different,
for possible cases of cross-compilation with `-Zgcc-ld=lld` but the
expectation is that it should be passed manually when needed in these
situations.
Remove wrapper functions for some unstable options
They are trivial and just forward to the option. Like most other options, we can just access it directly.
