Enum rustc_target::spec::FramePointer

source · [−]

pub enum FramePointer {
    Always,
    NonLeaf,
    MayOmit,
}

Variants

`Always`

Forces the machine code generator to always preserve the frame pointers.

`NonLeaf`

Forces the machine code generator to preserve the frame pointers except for the leaf functions (i.e. those that don’t call other functions).

`MayOmit`

Allows the machine code generator to omit the frame pointers.

This option does not guarantee that the frame pointers will be omitted.
