* Uncomment some i64-related instruction assertions now that LLVM
supports the opcodes.
* Fix the codegen for `{i,u}32x4_trunc_sat_f32x4`. This was originally
introduced using `simd_cast` but that inherits LLVM's UB related to
float-to-integer casts out of bounds. Since the original inception of
these intrinsics in LLVM dedicated intrinsics for the wasm
instructions have been added, so this swithces the implementation to
using those.
* Uncomment `f64x2_convert_low_i32x4` instruction assertion and add a
test now that this is implemented in Wasmtime.
This lint is allow by default, which is why this wasn't spotted earlier.
It's denied by rust-lang/rust, so it's good to warn about it here so it
can be fixed more quickly.
While they're not very useful in single-threaded mode this makes them
more useful for building libraries because you don't have to always
recompile the standard library to get the desired effect. Additionally
it helps us enable tests on CI for these functions, since the
instructions will now validate without shared memory (thankfully!).
* Sync with the latest LLVM which has a few new intrinsic names
* Move explicit tests back to `assert_instr` since `assert_instr` now
supports specifying const-generic arguments inline.
* Enable tests where wasmtime implements the instruction as well as LLVM.
* Ensure there are tests for all functions that can be tested at this
time (those that aren't unimplemented in wasmtime).
There's still a number of `assert_instr` tests that are commented out.
These are either because they're unimplemented in wasmtime at the moment
or LLVM doesn't have an implementation for the instruction yet.
Due to commit 902ea588eab849e7254d3bc76abf32d833ac0dd6 in the
llvm-project i32.atomic.wait and i64.atomic.wait got renamed to
memory.atomic.wait32 and memory.atomic.wait64.
