alexcrichton opened PR #9403 from alexcrichton:wide-arithmetic to bytecodealliance:main:

This commit implements the [wide-arithmetic] proposal in Wasmtime. This is a pretty easy proposal to implement due to Cranelift already having support for all the various instructions. The features implemented here are:

• Cranelift support for the four new instructions.
• A new Config::wasm_wide_arithmetic option.
• A new -Wwide-arithmetic CLI flag.
• A new wasmtime_config_wasm_wide_arithmetic_set C API function.
• Support for fuzzing this proposal
  • Generation is implemented in wasm-smith .
  • While it's off-by-default in wasm-smith it's enabled-by-default here.
  • Differential execution is only possible against Wasmtime right now.
  • Single-instruction module support was added for these new instructions.
• Tests for some simple cases plus randomly-generated tests.
• Example disassemblies for new instructions on Cranelift architectures.
