Struct TargetConfig 

pub struct TargetConfig {
    pub stack_pointer: PReg,
    pub frame_pointer: PReg,
    pub flags: Option<PReg>,
    pub addr_class: RegClass,
    pub move_caps: MoveCaps,
    pub max_mem_operands: u8,
    pub conds: &'static [&'static str],
}

The registers with fixed jobs, and the target-wide limits, for Target::new.

Examples

use backend_lang::target::TargetConfig;
use backend_lang::x86_64::{self, RSP};

let cfg = TargetConfig::of(&x86_64::TARGET);
assert_eq!(cfg.stack_pointer, RSP);

Fields

stack_pointer: PReg

The stack pointer.

frame_pointer: PReg

The frame pointer.

flags: Option<PReg>

The condition-flags register, if the ISA has one.

addr_class: RegClass

The class of a memory operand’s base and index registers.

move_caps: MoveCaps

How values move.

max_mem_operands: u8

The most memory operands one instruction may have.

conds: &'static [&'static str]

The condition codes’ names, indexed by CondCode::code (at most 255).

Implementations

impl TargetConfig

pub const fn of(target: &Target) -> TargetConfig

Examples

use backend_lang::target::TargetConfig;
use backend_lang::x86_64;

assert_eq!(TargetConfig::of(&x86_64::TARGET).conds.len(), 16);
