Struct FinalizedMachCallSite

Source
pub struct FinalizedMachCallSite<'a> {
    pub ret_addr: CodeOffset,
    pub frame_offset: Option<u32>,
    pub exception_handlers: &'a [FinalizedMachExceptionHandler],
}
Expand description

A call site record resulting from a compilation.

Fields§

§ret_addr: CodeOffset

The offset of the call’s return address, relative to the start of the buffer.

§frame_offset: Option<u32>

The offset from the FP at this callsite down to the SP when the call occurs, if known. In other words, the size of the stack frame up to the saved FP slot. Useful to recover the start of the stack frame and to look up dynamic contexts stored in ExceptionContextLoc::SPOffset.

If None, the compiler backend did not specify a frame offset. The runtime in use with the compiled code may require the frame offset if exception handlers are present or dynamic context is used, but that is not Cranelift’s concern: the frame offset is optional at this level.

§exception_handlers: &'a [FinalizedMachExceptionHandler]

Exception handlers at this callsite, with target offsets relative to the start of the buffer.
