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

Implementations

impl CallConv

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

Return the default calling convention for the given target triple.
