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 tweak aarch64 ABI.

BaldrdashSystemV

SpiderMonkey WebAssembly convention on systems using natively SystemV.

BaldrdashWindows

SpiderMonkey WebAssembly convention on Windows.

Baldrdash2020

SpiderMonkey WebAssembly convention for “ABI-2020”, with extra TLS register slots in the frame.

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.

Implementations

impl CallConv[src]

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

Return the default calling convention for the given target triple.

pub fn for_libcall(flags: &Flags, default_call_conv: CallConv) -> Self[src]
