Enum target_lexicon::CallingConvention

pub enum CallingConvention {
    SystemV,
    WasmBasicCAbi,
    WindowsFastcall,
    AppleAarch64,
}

The calling convention, which specifies things like which registers are used for passing arguments, which registers are callee-saved, and so on.

Variants

SystemV

“System V”, which is used on most Unix-like platfoms. Note that the specific conventions vary between hardware architectures; for example, x86-32’s “System V” is entirely different from x86-64’s “System V”.

WasmBasicCAbi

The WebAssembly C ABI. https://github.com/WebAssembly/tool-conventions/blob/master/BasicCABI.md

WindowsFastcall

“Windows Fastcall”, which is used on Windows. Note that like “System V”, this varies between hardware architectures. On x86-32 it describes what Windows documentation calls “fastcall”, and on x86-64 it describes what Windows documentation often just calls the Windows x64 calling convention (though the compiler still recognizes “fastcall” as an alias for it).

AppleAarch64

Apple Aarch64 platforms use their own variant of the common Aarch64 calling convention.
