Previously (as in an hour ago) #3905 landed a new ability for fuzzing to arbitrarily insert padding between functions. Running some fuzzers locally though this instantly hit a lot of problems on AArch64 because the arbitrary padding isn't aligned to 4 bytes like all other functions are. To fix this issue appending functions now correctly aligns the output as appropriate for the platform. The alignment argument for appending was switched to `None` where `None` means "use the platform default" and otherwise and explicit alignment can be specified for inserting other data (like arbitrary padding or Windows unwind tables).
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
