Commit 7d36fd9a1e avoided these
x86-specific tests altogether. This change avoids any dependency on x86
entirely by specifying a frontend configuration (SystemV + U64); this is
enough information for the `FunctionBuilder` to correctly generate the
syscalls.
This crate provides a straightforward way to create a
Cranelift IR function and fill it with
instructions translated from another language. It contains an SSA construction
module that provides convenient methods for translating non-SSA variables into
SSA Cranelift IR values via use_var and def_var calls.
