Bindings and assignment
var total accepts later assignments. let answer receives one initialization. That source distinction decides which stores the compiler permits and which old values must be released when a store happens.
Start with one changing name
The example begins with the unknown command-line count, adds two, then freezes the result under a new name. In MIR, the change is a local_set. In optimized assembly, a scalar local may disappear into a register entirely.

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.
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.
add.i64- Adds two signed 64-bit integers. The type suffix selects the overflow and representation rules.
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.
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.
mul- Multiplies integers after the language-specific checks have been represented.
ret- Returns a status or value and ends the current basic block.
@llvm.sadd.with.overflow.i64- Returns a signed sum together with the overflow bit required by checked addition.
@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_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.

ARM64 object code. LLVM selected these instructions, registers, calls, and branch conditions for this target.
open assembly fileARM64 instruction guide hover, focus, or tap dotted terms
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.
adds- Adds and updates the negative, zero, carry, and overflow flags for a following conditional instruction.
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.
cset- Writes 1 or 0 according to a condition, producing a Boolean value from processor flags.
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.hs- Branches when an unsigned comparison found higher-or-same, represented by a set carry flag.
b.vs- Branches when the arithmetic overflow flag is set.
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.

Let, var, and the thing they name
let
The binding keeps the same value or object identity. A class or container may still mutate because the binding continues to name that object.
var
The binding may be replaced. It can carry an annotation, an initializer, or both. When the initializer is omitted, a zeroable type supplies its zero value.
let names = ["Ada"]
names.append("Grace") # object mutates; binding is still names
var count: i64 = 1
count = count + 1 # binding is replacedReplacement is an ownership transaction
For a reference place, assignment prepares the new value before releasing the old one. That order matters when both names denote the same object, when evaluation can trap, and when last release runs a deinitializer or closes a resource.
- Resolve the placeLocal, field, nested field, index, slice, compound target, or parallel destination.
- Evaluate and retain replacementsEvery right-side expression and conversion completes first.
- Commit storesA guarded multi-place assignment commits all replacement stores or none.
- Release old ownershipOld references leave in the language-defined order; last release may have visible cleanup.
One assignment subsystem, many places
semantics/assign.zig plans simple, compound, field, index, chained, and parallel assignments. The planner records the destination's mutability, element type, optional guard, and write-back behavior into HIR. A writing value method is another kind of place update: the modified receiver must be stored back into a mutable bare local.
Zero initialization has limits
Numeric and Boolean values, optionals, and aggregates built from zeroable fields can initialize from their type’s zero. Function and interface values require an initializer or an optional slot. The resolved type determines which case applies.
How weak storage works
A weak var local or weak field has an explicit optional target type. Assignment stores a generation-checked handle without retaining. Every read attempts an owned strong snapshot and answers none after the target dies.
Each weak read is a separate upgrade attempt. Bind one upgraded snapshot, unwrap that stable value, and use it for the rest of the operation.
Every exit closes its scope
return, break, continue, fallible propagation, and ordinary block exit release the locals and statement temporaries they leave. Semantics records those cleanup obligations; MIR makes them explicit on each control-flow edge.
