Functions
constexpr std::string_view	contur::instructionName (Instruction instr) noexcept
	Returns the human-readable mnemonic for an instruction.
constexpr std::string_view	contur::interruptName (Interrupt intr) noexcept
	Returns the human-readable name for an interrupt code.
constexpr bool	contur::isArithmetic (Instruction instr) noexcept
	Returns true if the instruction is an arithmetic operation (Add, Sub, Mul, Div).
constexpr bool	contur::isLogic (Instruction instr) noexcept
	Returns true if the instruction is a logic/bitwise operation (And, Or, Xor, Shift).
constexpr bool	contur::isJump (Instruction instr) noexcept
	Returns true if the instruction is a conditional or unconditional jump.
constexpr bool	contur::isStackOp (Instruction instr) noexcept
	Returns true if the instruction affects the stack (Push, Pop, Call, Return).
constexpr bool	contur::isMemoryOp (Instruction instr) noexcept
	Returns true if the instruction involves memory access (ReadMemory, WriteMemory).
constexpr bool	contur::isHalt (Instruction instr) noexcept
	Returns true if the instruction terminates execution flow (Halt, Interrupt with Exit).

Variables
constexpr std::uint8_t	contur::INSTRUCTION_COUNT = 25
	Total number of defined instructions.

Detailed Description

ISA (Instruction Set Architecture) constants and helpers.

Provides constexpr utility functions for instruction decoding, name lookup, and classification. All functions are header-only and suitable for compile-time evaluation.
