- 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.
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
