input some zig code that looks like this:
pub const x86_64 = struct {
/// only give out 32bit addresses
pub const @"32BIT" = 0x40;
/// stack-like segment
pub const GROWSDOWN = 0x0100;
/// ETXTBSY
pub const DENYWRITE = 0x0800;
/// mark it as an executable
pub const EXECUTABLE = 0x1000;
/// pages are locked
pub const LOCKED = 0x2000;
/// don't check for reservations
pub const NORESERVE = 0x4000;
// common to all architectures except mips
/// Interpret addr exactly
pub const FIXED = 0x10;
/// don't use a file (NON MIPS)
pub const ANONYMOUS = 0x20;
// MAP_ 0x0100 - 0x4000 flags are per architecture
/// populate (prefault) pagetables (NON MIPS)
pub const POPULATE = 0x8000;
/// do not block on IO (NON MIPS)
pub const NONBLOCK = 0x10000;
/// give out an address that is best suited for process/thread stacks (NON MIPS)
pub const STACK = 0x20000;
/// create a huge page mapping (NON MIPS)
pub const HUGETLB = 0x40000;
/// perform synchronous page faults for the mapping
pub const SYNC = 0x80000;
/// MAP_FIXED which doesn't unmap underlying mapping
pub const FIXED_NOREPLACE = 0x100000;
/// For anonymous mmap, memory could be uninitialized
pub const UNINITIALIZED = 0x4000000;
};
pub const x86 = struct {
pub const NORESERVE = 0x4000;
pub const GROWSDOWN = 0x0100;
pub const DENYWRITE = 0x0800;
pub const EXECUTABLE = 0x1000;
pub const LOCKED = 0x2000;
pub const @"32BIT" = 0x40;
// common to all architectures except mips
/// Interpret addr exactly
pub const FIXED = 0x10;
/// don't use a file (NON MIPS)
pub const ANONYMOUS = 0x20;
// MAP_ 0x0100 - 0x4000 flags are per architecture
/// populate (prefault) pagetables (NON MIPS)
pub const POPULATE = 0x8000;
/// do not block on IO (NON MIPS)
pub const NONBLOCK = 0x10000;

pub const FIXED_NOREPLACE = 0x100000;
/// For anonymous mmap, memory could be uninitialized
pub const UNINITIALIZED = 0x4000000;
};and outputs this:
