It is the next evolution in the development of -wasi (the [WebAssembly System Interface](https://wasi.dev)) that uses the WebAssembly -[component model] to allow for a standardized set of syscalls that are intended to empower -WebAssembly binaries with native host capabilities. - -[component model]: https://github.com/WebAssembly/component-model - -## Target maintainers - -- Alex Crichton, https://github.com/alexcrichton -- Ryan Levick, https://github.com/rylev - -## Requirements - -This target is cross-compiled. The target supports `std` fully. - -## Platform requirements - -The WebAssembly runtime should support the wasi preview 2 API set. - -This target is not a stable target. This means that there are only a few engines -which implement wasi preview 2, for example: - -* Wasmtime - `-W component-model` diff --git a/tests/assembly/targets/targets-elf.rs b/tests/assembly/targets/targets-elf.rs index dee0fa9f4a410..41f5df0fba001 100644 --- a/tests/assembly/targets/targets-elf.rs +++ b/tests/assembly/targets/targets-elf.rs @@ -489,9 +489,6 @@ // revisions: wasm64_unknown_unknown // [wasm64_unknown_unknown] compile-flags: --target wasm64-unknown-unknown // [wasm64_unknown_unknown] needs-llvm-components: webassembly -// revisions: wasm32_wasi_preview2 -// [wasm32_wasi_preview2] compile-flags: --target wasm32-wasi-preview2 -// [wasm32_wasi_preview2] needs-llvm-components: webassembly // revisions: x86_64_fortanix_unknown_sgx // [x86_64_fortanix_unknown_sgx] compile-flags: --target x86_64-fortanix-unknown-sgx // [x86_64_fortanix_unknown_sgx] needs-llvm-components: x86 diff --git a/tests/ui/check-cfg/well-known-values.stderr b/tests/ui/check-cfg/well-known-values.stderr index d7d538c0b9e3e..814d473619777 100644 --- a/tests/ui/check-cfg/well-known-values.stderr +++ b/tests/ui/check-cfg/well-known-values.stderr @@ -125,7 +125,7 @@ warning: unexpected `cfg` condition value: `_UNEXPECTED_VALUE` LL | target_env = "_UNEXPECTED_VALUE", | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | - = note: expected values for `target_env` are: ``, `eabihf`, `gnu`, `gnueabihf`, `msvc`, `musl`, `newlib`, `nto70`, `nto71`, `ohos`, `preview2`, `psx`, `relibc`, `sgx`, `uclibc` + = note: expected values for `target_env` are: ``, `eabihf`, `gnu`, `gnueabihf`, `msvc`, `musl`, `newlib`, `nto70`, `nto71`, `ohos`, `psx`, `relibc`, `sgx`, `uclibc` = note: see for more information about checking conditional configuration warning: unexpected `cfg` condition value: `_UNEXPECTED_VALUE` @@ -134,7 +134,7 @@ warning: unexpected `cfg` condition value: `_UNEXPECTED_VALUE` LL | target_family = "_UNEXPECTED_VALUE", | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | - = note: expected values for `target_family` are: `unix`, `wasi`, `wasm`, `windows` + = note: expected values for `target_family` are: `unix`, `wasm`, `windows` = note: see for more information about checking conditional configuration warning: unexpected `cfg` condition value: `_UNEXPECTED_VALUE`
