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.

pub fn for_libcall(flags: &Flags, default_call_conv: CallConv) -> CallConv

Returns the calling convention used for libcalls according to the current flags.

pub fn extends_windows_fastcall(self) -> bool

Is the calling convention extending the Windows Fastcall ABI?

pub fn extends_baldrdash(self) -> bool

Is the calling convention extending the Baldrdash ABI?
