Struct cranelift_codegen::settings::FlagsOrIsa

pub struct FlagsOrIsa<'a> {
    pub flags: &'a Flags,
    pub isa: Option<&'a dyn TargetIsa>,
}

Wrapper containing flags and optionally a TargetIsa trait object.

A few passes need to access the flags but only optionally a target ISA. The FlagsOrIsa wrapper can be used to pass either, and extract the flags so they are always accessible.

Fields

flags: &'a Flags

Flags are always present.

isa: Option<&'a dyn TargetIsa>

The ISA may not be present.
