The goal here is to enable Wasmtime to compile forarchitectures that it has no prior knowledge of. There's a fewmiscellaneous locations through Wasmtime where we needarchitecture-specific intrinsics and such but that's all in service ofCranelift itself. Without Cranelift support none of them are necessary.This commit plumbs a custom `#[cfg]` from Wasmtime's `build.rs` scriptinto the crate about whether there's a supported Cranelift backend. Ifthis isn't available some architecture-specific intrinsics are turnedoff and not included. An example is that `vm::arch` entirely disappearswhich is only in service of `UnwindHost`, which also disappears.Furthermore the `helpers.c` file also entirely disappears as it's notnecessary on unknown architectures.To help keep this working I've added CI to build Wasmtime for`powerpc64le-unknown-linux-gnu`. Wasmtime currently has no support forthis architecture, although if it grows such support in the futurethis'll need to be changed to some other unsupported architecture.* Review feedback* Fix powerpc build* Refactor windows trap handling to look like UnixShuffle some files around to be more amenable to #[cfg]* Move signal-handling tests to wasmtime crateThat way it's got easy access to the #[cfg]'s from the build script* Disable signals support without a host compilerEven if custom signals are enabled, don't compile it in.prtest:full* Fix windows unused imports* Fix unused imports on Windows* Remove untested stubs for arch intrinsicsThese aren't needed any more to compile Pulley* Defer tunables validation to loading modulesInstead of validating at `Engine` config time instead validate at`Module` config time to enable cross-compilation.* Skip `Tunables` auto-configuration if cross-compilingThis commit* Tweak some Tunables based on PulleyEnsures that specific `--target pulleyNN` works most of the time.* Update host_segfault.rs to handle new 32-bit defaultsNo signal handlers are used at all with Pulley so when the async stackoverflows there's no message printed any more.* Disable Tunables::signals_based_traps on miri List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/sys/windows/mod.rs Tue, 28 Jan 2025 01:06:27 +0000 Alex Crichton <alex@alexcrichton.com> http://172.16.0.5:8080/history/wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/sys/windows/mod.rs#7f9049b9 Replace `signals-based-traps` with auto-detection (#9941)* Replace `signals-based-traps` with auto-detectionThis commit refactors the platform support of the `wasmtime` crateitself to remove the previously added `signals-based-traps` feature infavor of auto-detecting whether it's there or not. The `build.rs`script for the `wasmtime` crate will now detect the target platform andauto-enable this feature as necessary.The `signals-based-traps` cargo feature is removed and split into twocustom `#[cfg]` directives that the build script sets:* `has_virtual_memory` - this is used to gate mmap implementations for example. This is enabled on `unix || windows` and will be off for `no_std` targets for example. This is split out of "signals-based-traps" to better handle platforms like iOS which have virtual memory but don't execute native code (removing the need for native signals).* `has_native_signals` - gates signal handlers on Unix for example. This is disabled on MIRI but otherwise enabled for `unix || windows`. This is intended to in the future get disabled for iOS by default for example since it's not necessary when using Pulley. This is additionally off-by-default for `no_std` platforms.Two new crate features were added for `no_std` or "custom" platforms toopt-in to the `wasmtime-platform.h` C APIs for implementing virtualmemory and signals. These are used in the `min-platform` embedding example.This commit additionally updates some various documentation here andthere to be more up-to-date.* Update CI configuration* Fix compile warnings* Fix test on miri* Fix more tests on miri* Fix some warnings* Another round of miri/CI attempts/fixesprtest:full List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/sys/windows/mod.rs Wed, 15 Jan 2025 01:15:14 +0000 Alex Crichton <alex@alexcrichton.com> http://172.16.0.5:8080/history/wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/sys/windows/mod.rs#5442662a Fix build on 32-bit Windows; consolidate CI platform checks (#9883)* Fix build on 32-bit Windows; consolidate CI platform checksThis commit fixes the build of the `wasmtime` crate and CLI on 32-bitWindows. This required adding some extra bits for trap handling and astub for "unimplemented" for unwind information registration.

With `no_std` becomingofficially supported this should provide a better onboarding experiencewhere the fallback custom platform is used. This will cause linkererrors if the symbols aren't implemented and searching/googling shouldlead back to our docs/repo (eventually, hopefully).* Change Wasmtime's TLS state to a single pointerThis commit updates the management of TLS to rely on just a singlepointer rather than a pair of a pointer and a `bool`. Additionallymanagement of the TLS state is pushed into platform-specific modules toenable different means of managing it, namely the "custom" platform nowhas a C function required to implement TLS state for Wasmtime.* Delay conversion to `Instant` in atomic intrinsicsThe `Duration` type is available in `no_std` but the `Instant` type isnot. The intention is to only support the `threads` proposal if `std` isactive but to assist with this split push the `Duration` further intoWasmtime to avoid using a type that can't be mentioned in `no_std`.* Gate more parts of Wasmtime on the `profiling` featureMove `serde_json` to an optional dependency and gate the guest profilerentirely on the `profiling` feature.* Refactor conversion to `anyhow::Error` in `wasmtime-environ`Have a dedicated trait for consuming `self` in addition to a`Result`-friendly trait.* Gate `gimli` in Wasmtime on `addr2line`Cut down the dependency list if `addr2line` isn't enabled since thenthe dependency is not used. While here additionally lift the versionrequirement for `addr2line` up to the workspace level.* Update `bindgen!` to have `no_std`-compatible outputPull most types from Wasmtime's `__internal` module as the source oftruth.* Use an `Option` for `gc_store` instead of `OnceCell`No need for synchronization here when mutability is already available inthe necessary contexts.* Enable embedder-defined host feature detection* Add `#![no_std]` support to the `wasmtime` crateThis commit enables compiling the `runtime`, `gc`, and `component-model`features of the `wasmtime` crate on targets that do not have `std`. Thistags the crate as `#![no_std]` and then updates everything internally toimport from `core` or `alloc` and adapt for the various idioms.
