abort

public · function · Source (opens in a new tab)

llvm::FunctionCallee sun::codegen::intrinsics::abort(llvm::Module *m)

void abort(void)

accept

public · function · Source (opens in a new tab)

llvm::FunctionCallee sun::codegen::intrinsics::accept(llvm::Module *m)

int accept(int fd, struct sockaddr *addr, socklen_t *len)

bind

public · function · Source (opens in a new tab)

llvm::FunctionCallee sun::codegen::intrinsics::bind(llvm::Module *m)

int bind(int fd, const struct sockaddr *addr, socklen_t len)

buildSockaddrIn

public · function · static · Source (opens in a new tab)

static Value * sun::codegen::intrinsics::buildSockaddrIn(IRBuilder<> &builder, LLVMContext &llvmCtx, Value *ip, Value *port, bool isDarwin)

Fill a 16-byte stack sockaddr_in: family/port/addr, rest zeroed.

Port and addr sit at offsets 2 and 4 everywhere; the first two bytes differ per OS. Linux has a 16-bit sa_family_t at offset 0; Darwin splits them into a one-byte sin_len (the struct size) followed by a one-byte sin_family — a little-endian 16-bit store of AF_INET there would set sin_len=2 and sin_family=0 (AF_UNSPEC), so the bytes are stored individually. Port arrives in host order; sin_port is big-endian, hence the bswap16.

close

public · function · Source (opens in a new tab)

llvm::FunctionCallee sun::codegen::intrinsics::close(llvm::Module *m)

int close(int fd)

connect

public · function · Source (opens in a new tab)

llvm::FunctionCallee sun::codegen::intrinsics::connect(llvm::Module *m)

int connect(int fd, const struct sockaddr *addr, socklen_t len)

emitLibcWriteInline

public · function · static · Source (opens in a new tab)

static Value * sun::codegen::intrinsics::emitLibcWriteInline(IRBuilder<> &builder, llvm::Module *module, Value *fd, Value *buf, Value *len)

Emits a C library write call for the supplied descriptor and bytes.

extractSockaddrInParts

public · function · static · Source (opens in a new tab)

static void sun::codegen::intrinsics::extractSockaddrInParts(IRBuilder<> &builder, LLVMContext &llvmCtx, Value *sockaddr, Value *outIp, Value *outPort)

Load sin_addr (offset 4, left in network order) and sin_port (offset 2, swapped to host order and widened to i32) out of a sockaddr_in, storing them through the two out-pointers.

forwarder

public · function · Source (opens in a new tab)

llvm::Function * sun::codegen::intrinsics::forwarder(llvm::Module *module, const char *wrapperName, llvm::FunctionCallee callee, llvm::ArrayRef< llvm::Type * > params, llvm::Type *retTy)

A thin internal wrapper around one libc function: the wrapper's signature matches the Sun intrinsic, the body is a single forwarding call.

Keeping the __sun_* wrapper preserves the intrinsic symbol names that existing call sites and .moon symbol handling rely on.

free

public · function · Source (opens in a new tab)

llvm::FunctionCallee sun::codegen::intrinsics::free(llvm::Module *m)

void free(void *ptr)

fstat

public · function · Source (opens in a new tab)

llvm::FunctionCallee sun::codegen::intrinsics::fstat(llvm::Module *m)

int fstat(int fd, struct stat *buf) — the buffer layout is the target libc's struct stat; Sun-side callers own that interpretation

fsync

public · function · Source (opens in a new tab)

llvm::FunctionCallee sun::codegen::intrinsics::fsync(llvm::Module *m)

int fsync(int fd)

ftruncate

public · function · Source (opens in a new tab)

llvm::FunctionCallee sun::codegen::intrinsics::ftruncate(llvm::Module *m)

int ftruncate(int fd, off_t length)

futexSyscallNumber

public · function · static · Source (opens in a new tab)

static int64_t sun::codegen::intrinsics::futexSyscallNumber(const llvm::Module *module)

The futex syscall number is the one per-target constant left in thread support — it is data, not assembly, so each Linux target is one table row.

Darwin never reaches this: its targets take the ulock path instead.

get

public · function · Source (opens in a new tab)

llvm::FunctionCallee sun::codegen::intrinsics::get(llvm::Module *module, llvm::StringRef name, llvm::Type *ret, llvm::ArrayRef< llvm::Type * > params, bool isVarArg=false)

Finds or declares a C runtime function with the requested LLVM signature.

Convert intrinsic function name to enum Returns Intrinsic::None if not recognized.

Get or create the __sun_print_i64 or __sun_print_u64 helper function.

Same digit-extraction shape as the i32 helper, widened to 64 bits. Digits are always extracted unsigned; the signed variant first takes the absolute value and later writes the minus sign, the unsigned variant prints the whole 64-bit value as is. Buffer is 24 bytes: the longest output is "18446744073709551615" or "-9223372036854775808" (20 chars each).

static Function * sun::codegen::intrinsics::getOrCreatePrintCharHelper(llvm::Module *module, LLVMContext &llvmCtx)

void __sun_print_char(i32 scalar) — write one char to stdout as UTF-8.

Branch-free: all four bytes are computed with selects and stored into a 4-byte buffer, then only the first len of them are written. A scalar value that is somehow out of range (only reachable through an unchecked _convert) is written as U+FFFD rather than as invalid UTF-8.

requiresUnsafeBlock

requiresUnsafeBlock(const std::string &name)

public · function · Source (opens in a new tab)

bool sun::codegen::intrinsics::requiresUnsafeBlock(const std::string &name)

Reports whether the named intrinsic may only be called in unsafe code.

requiresUnsafeBlock(Intrinsic i)

public · function · Source (opens in a new tab)

bool sun::codegen::intrinsics::requiresUnsafeBlock(Intrinsic i)

Does this intrinsic have to be written inside an unsafe { } block?

The line is whether it reads or writes memory nothing has checked: through a raw pointer, or across the boundary into libc and the kernel. Intrinsics that only compute — a size, a type check, an address, a numeric conversion — are safe, and so are the print intrinsics, which the standard library treats as ordinary output. Semantic analysis is the one place this is applied, for generic and non-generic intrinsics alike.
