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.

Layout
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
