- Properly mask constant values down to appropriate width when
generating a constant value directly in aarch64 backend. This was a
miscompilation introduced in the new-isel refactor. In combination
with failure to respect NarrowValueMode, this resulted in a very
subtle bug when an `i32` constant was used in bit-twiddling logic.
- Add support for `iadd_ifcout` in aarch64 backend as used in explicit
heap-check mode. With this change, we no longer fail heap-related
tests with the huge-heap-region mode disabled.
- Remove a panic that was occurring in some tests that are currently
ignored on aarch64, by simply returning empty/default information in
`value_label` functionality rather than touching unimplemented APIs.
This is not a bugfix per-se, but removes confusing panic messages from
`cargo test` output that might otherwise mislead.
`EncCursor` is a variant of `Cursor` that allows updating CLIF while
keeping its encodings up to date, given a particular ISA. However, new
(MachInst) backends don't use the encodings, and the `TargetIsaAdapter`
shim will panic if any encoding-related method is called. This PR avoids
those panics.
Fixes#1809.
The `convert_i64x2_imul` custom legalization checks the ISA flags for AVX512DQ or AVX512VL support and legalizes `imul.i64x2` to an `x86_pmullq` in this case; if not, it uses a lengthy SSE2-compatible instruction sequence.
Without this special instruction, legalizing to the AVX512 instruction AND the SSE instruction sequence is impossible. This extra instruction would be rendered unnecessary by the x64 backend.

fix(tagged-union): removed local dependency and changed to point to 0.9.1 version of wasi
fix(tagged-union): added newline to gitignore, changed wasi version to 0.10.0
fix(tagged-union): removed gitignore as Cargo.lock is intentional
* Moves CodeMemory, VMInterrupts and SignatureRegistry from Compiler
* CompiledModule holds CodeMemory and GdbJitImageRegistration
* Store keeps track of its JIT code
* Makes "jit_int.rs" stuff Send+Sync
* Adds the threads example.
This avoids the set uniqueness (hashing) test, reduces memory
churn when re-mapping virtual register onto real registers, and is
generally more memory-efficient.
