This patch implements, for aarch64, the following wasm SIMD extensions i32x4.dot_i16x8_s instruction https://github.com/WebAssembly/simd/pull/127 It also updates dependencies as follows, in order that the new instruction can be parsed, decoded, etc: wat to 1.0.27 wast to 26.0.1 wasmparser to 0.65.0 wasmprinter to 0.2.12 The changes are straightforward: * new CLIF instruction `widening_pairwise_dot_product_s` * translation from wasm into `widening_pairwise_dot_product_s` * new AArch64 instructions `smull`, `smull2` (part of the `VecRRR` group) * translation from `widening_pairwise_dot_product_s` to `smull ; smull2 ; addv` There is no testcase in this commit, because that is a separate repo. The implementation has been tested, nevertheless.
This is the wasmtime-environ crate, which contains the implementations
of the ModuleEnvironment and FuncEnvironment traits from
cranelift-wasm. They effectively
implement an ABI for basic wasm compilation that defines how linear memories
are allocated, how indirect calls work, and other details. They can be used
for JITing, native object files, or other purposes.
