Struct CallInfo

pub struct CallInfo<T> {
    pub dest: T,
    pub uses: SmallVec<[CallArgPair; 8]>,
    pub defs: SmallVec<[CallRetPair; 8]>,
    pub clobbers: PRegSet,
    pub callee_conv: CallConv,
    pub caller_conv: CallConv,
    pub callee_pop_size: u32,
}

Out-of-line data for calls, to keep the size of Inst down.

Fields

dest: T

Receiver of this call

uses: SmallVec<[CallArgPair; 8]>

Register uses of this call.

defs: SmallVec<[CallRetPair; 8]>

Register defs of this call.

clobbers: PRegSet

Registers clobbered by this call, as per its calling convention.

callee_conv: CallConv

The calling convention of the callee.

caller_conv: CallConv

The calling convention of the caller.

callee_pop_size: u32

The number of bytes that the callee will pop from the stack for the caller, if any. (Used for popping stack arguments with the tail calling convention.)

Implementations

impl<T> CallInfo<T>

pub fn empty(dest: T, call_conv: CallConv) -> CallInfo<T>

Creates an empty set of info with no clobbers/uses/etc with the specified ABI

pub fn map<U>(self, f: impl FnOnce(T) -> U) -> CallInfo<U>

Change the T payload on this info to U.

Trait Implementations
