Expand description

Calling convention identifiers.

Variants

`Fast`

Best performance, not ABI-stable.

`Cold`

Smallest caller code size, not ABI-stable.

`SystemV`

System V-style convention used on many platforms.

`WindowsFastcall`

Windows “fastcall” convention, also used for x64 and ARM.

`AppleAarch64`

Mac aarch64 calling convention, which is a tweaked aarch64 ABI.

`Probestack`

Specialized convention for the probestack function.

`WasmtimeSystemV`

Wasmtime equivalent of SystemV, not ABI-stable.

Currently only differs in how multiple return values are handled, returning the first return value in a register and everything else through a return-pointer.

`WasmtimeFastcall`

Wasmtime equivalent of WindowsFastcall, not ABI-stable.

Differs from fastcall in the same way as WasmtimeSystemV.

`WasmtimeAppleAarch64`

Wasmtime equivalent of AppleAarch64, not ABI-stable.

Differs from apple-aarch64 in the same way as WasmtimeSystemV.

Implementations

impl CallConv

pub fn triple_default(triple: &Triple) -> Self
