Enums, unions, and match
A union stores two things: which case is active and the data carried by that case. match reads the tag before it is allowed to read the payload.
Follow one tagged value
The example constructs State.running with a progress value and immediately matches it. MIR records the tag test and payload extraction. LLVM gives both a concrete layout. Optimization may remove the test when the active case is already known.

Luce MIR. Types, registers, blocks, calls, and lifetime operations form the instruction plan sent to the LLVM backend.

r7 is one typed intermediate value, %2 is a local storage slot, and b1 is a basic block. Read each block from top to bottom, then follow its final control-flow instruction.
Hover or focus a dotted term in the file for its explanation. On a touch screen, tap a term to keep the note open and tap elsewhere to close it. The list includes the operations that appear in this file.
union NAME- Declares a tagged value whose active case determines the payload layout and match path.
func …- Starts one MIR function and lists the source-level parameters with their resolved types.
local %N- Reserves a typed local slot. The slot gives later blocks a stable place to read or replace.
b0, b1, …- Names a basic block. Control enters at the label and runs until a branch, jump, trap, or return chooses what happens next.
r0, r1, …- Names one typed intermediate result. Each register is assigned once, which makes data flow explicit.
local_get- Reads a local slot into a fresh MIR register so this use has a precise value and type.
local_set- Writes a register into a local slot. Later blocks read that slot after control-flow paths join.
const- Creates a typed literal such as 2 or 10 inside the instruction stream.
equal.i64- Tests two signed 64-bit values for equality.
intrinsic NAME- Invokes a language operation with runtime rules recorded by the compiler. The name identifies the operation.
intrinsic len- Reads the logical length defined by the value's type, such as argument count or Unicode-scalar count.
intrinsic str_value- Converts a typed value into owned text through Luce's string conversion rules.
intrinsic print- Sends text through the installed host output capability.
intrinsic drop_storage- Releases any reference held by a temporary value and leaves that temporary in its empty state.
call NAME- Calls a resolved function directly. MIR already knows the target and argument order.
variant_make- Builds a tagged union value from a case tag and its payload.
variant_tag- Reads the active union case so control flow can select the matching arm.
variant_field- Reads the payload after the active case has been established.
branch CONDITION, TRUE, FALSE- Chooses one of two basic blocks from a Boolean register.
trap- Ends the run with a stable trap code and source position.
ret- Returns the current function's result to its caller and closes the current control-flow path.

%7 is an SSA value, i64 is a 64-bit integer type, ptr is a pointer, and @name is a module symbol. Numbered labels divide the function into basic blocks.
Hover or focus a dotted term in the file for its explanation. On a touch screen, tap a term to keep the note open and tap elsewhere to close it. The list includes the operations that appear in this file.
@name = …- Defines module data such as text constants, source positions, function records, and the artifact identity tag.
define … @name- Begins a generated function. The parameter attributes tell LLVM which pointers are valid, writable, or read-only.
declare … @name- Declares a runtime or LLVM helper whose body is provided elsewhere.
numeric label- Starts an LLVM basic block. Every branch names one of these labels as its destination.
%0, %1, …- Names an SSA value. Each name is assigned once, allowing LLVM to trace definitions and uses directly.
alloca- Reserves a stack slot for a local value, return area, or temporary aggregate.
getelementptr- Calculates the address of a field or indexed element while preserving LLVM's type and bounds information.
load- Copies a typed value from memory into an SSA value.
store- Copies an SSA value into a stack slot, object field, return area, or runtime structure.
icmp- Compares integers or pointers and produces the one-bit condition consumed by a branch or select.
br- Transfers control to another block. With an
i1operand it chooses between two destinations. select- Chooses one of two SSA values from a condition, which can become a branch-free machine instruction.
call- Invokes a generated function, a runtime helper, a host callback, or an LLVM intrinsic.
extractvalue- Reads one field from an SSA aggregate, such as the result and overflow bit returned together.
insertvalue- Builds an SSA aggregate one field at a time.
ptrtoint- Encodes a pointer as an integer field inside Luce's uniform runtime value representation.
inttoptr- Recovers a pointer from the integer field of Luce's uniform runtime value representation.
zext- Widens an unsigned value by filling the new high bits with zero.
trunc- Keeps the low bits while converting to a narrower integer representation.
lshr- Shifts bits right and fills the high side with zero; this is useful for unpacking handle fields.
and- Combines or masks bits, often to inspect a flag in a packed handle or status value.
or- Sets or combines bits in a packed value.
sub- Subtracts integer values; the generated entry code also uses it to update the call-depth budget.
mul- Multiplies integers after the language-specific checks have been represented.
ret- Returns a status or value and ends the current basic block.
@llvm.memcpy.inline- Copies a small fixed-size value representation; LLVM can expand it directly for the target.
@luce_rt_open- Creates the per-run runtime state and installs the table used to turn function numbers into source-aware traces.
@luce_rt_close- Closes the per-run runtime state after the final status and reports have been collected.
@luce_rt_args_list- Builds the owned
list[str]passed tomainfrom the host's argument callbacks. @luce_rt_status- Combines the generated function result with runtime trap, error, exhaustion, and exit state.
@luce_rt_report_error- Sends an uncaught recoverable error through the host's error-report callback.
@luce_rt_report- Sends the completed trap report through the host callback selected by the entry wrapper.
@luce_rt_leaked- Reads the live-object count used to detect references that remain after program cleanup.
@luce_rt_exhaust- Records allocation exhaustion in the current run so the entry wrapper returns the corresponding status.
@luce_rt_raise- Records a source-aware trap in the runtime so every execution path reports the same code and location.
@luce_rt_unwound- Adds one generated function frame while a trap or uncaught error travels toward the entry point.
@luce_rt_release- Removes a strong owner and triggers destruction at zero.
@luce_rt_drop_storage- Releases reference-bearing fields in a temporary runtime value.
@luce_rt_str- Converts a uniform runtime value into owned UTF-8 text.
@luce_rt_struct_make- Builds a value aggregate from typed fields while retaining any reference-bearing fields.
@luce_rt_files_install- Copies file-related callbacks from the host table into the current runtime context.
@luce_rt_sockets_install- Copies network callbacks from the host table into the current runtime context.
@luce_rt_graphics_install- Copies window and graphics callbacks from the host table into the current runtime context.
!prof- Attaches branch-probability metadata so LLVM can place common and failure paths efficiently.

x8 is a 64-bit register; w8 is its low 32 bits. A leading # marks a constant, brackets describe a memory address, and conditional instructions read the processor flags set by the preceding arithmetic or comparison.
Hover or focus a dotted term in the file for its explanation. On a touch screen, tap a term to keep the note open and tap elsewhere to close it. The list includes the operations that appear in this file.
mov- Copies a register value or loads a small constant. Calls also use it to place arguments in the required registers.
add- Adds registers or a constant. Address setup and stack restoration frequently use this instruction.
sub- Subtracts registers or a constant. Function prologues use it to reserve stack space.
cmp- Performs a subtraction solely to set condition flags; a following branch or select consumes those flags.
cmn- Performs an addition solely to set condition flags. The checked multiply-by-two path uses it to recognize unsafe inputs.
csel- Selects one of two registers from the current condition flags. The clamp uses it to choose the doubled value or limit.
ldr- Loads a register from memory using a scaled address offset.
str- Stores one register into memory using a scaled address offset.
ldp- Loads two adjacent registers, often restoring saved registers or reading neighboring fields.
stp- Stores two adjacent registers, often saving the caller's registers in a function prologue.
ldur- Loads from an unscaled byte offset, which is useful for stack slots below the frame pointer.
stur- Stores to an unscaled byte offset, which is useful for stack slots below the frame pointer.
ldurb- Loads one byte using an unscaled byte offset.
sturb- Stores one byte using an unscaled byte offset.
adrp- Loads the page address of a symbol. The linker fills in the final page-relative relocation.
bl- Calls a direct target and records the return address in
x30. blr- Calls the function address held in a register, as required for host callbacks and function values.
b- Jumps to another instruction address.
b.eq- Branches when the previous comparison reported equality.
b.ne- Branches when the previous comparison reported different values.
b.le- Branches when the signed left operand was smaller or equal.
b.hs- Branches when an unsigned comparison found higher-or-same, represented by a set carry flag.
cbz- Compares a register with zero and branches when it is zero.
cbnz- Compares a register with zero and branches when it contains a nonzero value.
tbnz- Tests one selected bit and branches when that bit is set; packed runtime flags use this form.
lsr- Shifts bits right and fills with zero, often extracting the upper field of a packed handle.
umaddl- Widens two 32-bit unsigned operands, multiplies them, and adds a 64-bit base address.
orr- Combines bits, commonly setting tag or flag bits in a packed value.
ret- Returns to the address in
x30and ends the current machine function.

Enums name integer states
An enum has an explicit or inferred integer backing width. Members are always namespaced. Converting a member to its number is explicit. Constructing from a number returns an optional because the backing representation can contain bit patterns outside the declared members.

Unions carry tagged payloads
A union member carries either an empty payload or named payload fields. Construction goes through the union namespace. The tag is always present; payload storage is sized and aligned for the alternatives. A match arm establishes the active tag before it receives that member’s fields.

Exhaustiveness turns change into a diagnostic
An enum or union match without else must cover every member. Adding a new alternative then finds each incomplete match at compile time. A union arm binds only the named fields of that member, with their exact types and ordinary value/reference lifetime.
Recursive values need a terminator
A union needs a finite payload layout. Recursive unions therefore cross an optional or reference boundary: absence can terminate a value chain, and a reference has fixed handle width regardless of the object graph behind it.
Finite
A recursive union member carries an optional next value or a list/class reference.
Infinite
A union member directly embeds the same union again with no terminating representation.
Equality, methods, and containers
Enums have value equality and may serve as map keys when the exact enum type matches. Union code compares the active tag through match and can compare payload fields whose own types define equality. Both enums and unions can declare methods and static functions; union member constructors are function values.
