alexcrichton added a commit to alexcrichton/rust that referenced this pull request
This commit is a continuation of the work originally proposed in
rust-lang/compiler-team#607 and later amended in
rust-lang/compiler-team#695. The end goal is to rename wasm32-wasi
to
wasm32-wasip1
to reflect WASI's development and distinguish the
preexisting target from the wasm32-wasip2
target that WASI is now
developing. Work for this transition began in rust-lang#120468 which landed in
Rust 1.78 which became stable on 2024-05-02.
This implements the next phase of the transition plan to warn on usage
of wasm32-wasi
. This is intended to help alert users that a removal is
pending and all release channels have the replacement available as well.
This will reach stable on 2024-09-05. The next stage of the plan is to
remove the wasm32-wasi
target some time in October 2024 which means
that the removal will reach stable on 2025-01-09. For reference a full
schedule of this transition is listed [here].
Currently this implementation is a simple unconditional warning whenever
rustc --target wasm32-wasi
is invoked. As-implemented there's no way
to turn off the warning other than to switch to the wasm32-wasip1
target.

This commit is the final step in the journey of renaming the historical
wasm32-wasi
target in the Rust compiler to wasm32-wasip1
. Various
steps in this journey so far have been:
- 2023-04-03: rust-lang/compiler-team#607 - initial proposal for this rename
- 2024-11-27: rust-lang/compiler-team#695 - amended schedule/procedure for rename
- 2024-01-29: rust-lang#120468 - initial introduction of
wasm32-wasip1
- 2024-06-18: rust-lang#126662 - warn on usage of
wasm32-wasi
- 2024-11-08: this PR - remove the
wasm32-wasi
target
The full transition schedule is in [this comment][comment] and is summarized with:
- 2024-05-02: Rust 1.78 released with
wasm32-wasip1
target - 2024-09-05: Rust 1.81 released warning on usage of
wasm32-wasi
- 2025-01-09: Rust 1.84 to be released without the
wasm32-wasi
target
This means that support on stable for the replacement target of
wasm32-wasip1
has currently been available for 6 months. Users have
already seen warnings on stable for 2 months about usage of
wasm32-wasi
and stable users have another 2 months of warnings before
the target is removed from stable.
This commit is intended to be the final step in this transition so the
source tree should no longer mention wasm32-wasi
except in historical
reference to the older name of the wasm32-wasip1
target.

target in the Rust compiler to wasm32-wasip1
. Various steps in this journey so far have been:
- 2023-04-03: rust-lang/compiler-team#607 - initial proposal for this rename
- 2024-11-27: rust-lang/compiler-team#695 - amended schedule/procedure for rename
- 2024-01-29: rust-lang#120468 - initial introduction of
wasm32-wasip1
- 2024-06-18: rust-lang#126662 - warn on usage of
wasm32-wasi
- 2024-11-08: this PR - remove the
wasm32-wasi
target
The full transition schedule is in [this comment][comment] and is summarized with:
- 2024-05-02: Rust 1.78 released with
wasm32-wasip1
target - 2024-09-05: Rust 1.81 released warning on usage of
wasm32-wasi
- 2025-01-09: Rust 1.84 to be released without the
wasm32-wasi
target
This means that support on stable for the replacement target of wasm32-wasip1
has currently been available for 6 months. Users have already seen warnings on stable for 2 months about usage of wasm32-wasi
and stable users have another 2 months of warnings before the target is removed from stable.
This commit is intended to be the final step in this transition so the source tree should no longer mention wasm32-wasi
except in historical reference to the older name of the wasm32-wasip1
target.

v1.84.0
==========================
Language
- Allow
#[deny]
inside#[forbid]
as a no-op - Show a warning when
-Ctarget-feature
is used to toggle features that can lead to unsoundness due to ABI mismatches - Use the next-generation trait solver in coherence
- Allow coercions to drop the principal of trait objects
- Support
/
as the path separator forinclude!()
in all cases on Windows - Taking a raw ref (
raw (const|mut)
) of a deref of a pointer (*ptr
) is now safe - Stabilize s390x inline assembly
- Stabilize Arm64EC inline assembly
- Lint against creating pointers to immediately dropped temporaries
- Execute drop glue when unwinding in an
extern "C"
function
Compiler
- Add
--print host-tuple
flag to print the host target tuple and affirm the "target tuple" terminology over "target triple" - Declaring functions with a calling convention not supported on the current target now triggers a hard error

- Enable XRay instrumentation for LoongArch Linux targets
- Extend the
unexpected_cfgs
lint to also warn in external macros - Stabilize WebAssembly

,reference-types
, andtail-call
target features - Added Tier 2 support for the

Compatibility Notes
- Enable by default the
LSX
target feature for LoongArch Linux targets - The unstable
-Zprofile
flag (“gcov-style” coverage instrumentation) has been removed. This does not affect the stable flags for coverage instrumentation (-Cinstrument-coverage
) and profile-guided optimization (-Cprofile-generate
,-Cprofile-use
), which are unrelated and remain available. - Support for the target named
wasm32-wasi
has been removed as the target is now namedwasm32-wasip1
. This completes the transition plan for this target following the introduction ofwasm32-wasip1
in Rust 1.78. Compiler warnings on use ofwasm32-wasi
introduced in Rust 1.81 are now gone as well as the target is removed. - [The syntax
&pin (mut|const) T
is now parsed as a type which in theory could affect macro expansion results in some edge cases](rust-lang/rust#130635 (comment)) - [Legacy syntax for calling
std::arch
functions is no longer permitted to declare items or bodies (such as closures, inline consts, or async blocks).](rust-lang/rust#130443 (comment)) - Declaring functions with a calling convention not supported on the current target now triggers a hard error
- The next-generation trait solver is now enabled for coherence, fixing multiple soundness issues
