ARM64 Instruction Encoding Helpers These functions provide type-safe instruction encoding for the ARM64 backend.

fn Gen.new(m &ssa.Module) &Gen

new creates a Gen value for arm64.

fn MachOObject.new() &MachOObject

new creates a MachOObject value for arm64.

Gen stores state for ARM64 code generation.

fn (mut g Gen) gen()

gen supports gen handling for Gen.

fn (mut g Gen) gen_parallel()

gen_parallel emits independent contiguous function ranges concurrently and merges their text, symbols, strings, and relocations in source order.

fn (mut g Gen) write_and_link(output string)

write_and_link writes and link output for arm64.

struct MachOObject {
pub mut:
	text_data []u8
	str_data  []u8
	data_data []u8

	relocs      []RelocationInfo
	symbols     []Symbol
	str_table   []u8
	sym_by_name map[string]int // symbol name → index in symbols
}

MachOObject represents mach oobject data used by arm64.

fn (mut m MachOObject) add_symbol(name string, addr u64, is_ext bool, sect u8) int

add_symbol updates add symbol state for MachOObject.

fn (mut m MachOObject) add_undefined(name string) int

add_undefined updates add undefined state for MachOObject.

fn (mut m MachOObject) add_reloc(addr int, sym_idx int, typ int, pcrel bool)

add_reloc updates add reloc state for MachOObject.

fn (mut m MachOObject) write(path string)

write supports write handling for MachOObject.
