-Instruction Set Reference
-=========================
-
-  NOP /* No operation */
-
-Privileged Instructions
------------------------
-
-  EI  /* Enable interrupts (privileged)  */
-  DI  /* Disable interrupts (privileged) */
-  SKEP %reg /* Set kernel entry point. */
-  TLBADD %virt, %phys, %flags /* Add entry to TLB */
-  TLBRM %virt /* Remove entry corresponding to a given virtual address. */
-  TLBFLUSH /* Flush all TLB entries */
-  JMPRU %reg /* Jump to location in a register and switch to user mode. */
-  RETI /* Return from interrupt (Restore shadow regs/PC, threads) */
-  HALT /* Stop CPU until next interrupt. */
-
-Memory Loads/Stores
--------------------
-
-  ST %reg, %reg, #imm /* Store reg to reg+imm */
-  LD %reg, %reg, #imm /* Load reg from reg+imm */
-
-Predicate Manipulation
-----------------------
-
-  ANDP @preg, @preg, @preg
-  ORP @preg, @preg, @preg
-  XORP @preg, @preg, @preg
-  NOTP @preg, @preg
-
-Value Tests
------------
-
-  RTOP @preg, %reg  /* Register to predicate. Same as ISZERO => NOTP */
-  ISNEG @preg, %reg
-  ISZERO @preg, %reg
-
-Immediate Integer Arithmetic/Logic
-----------------------------------
-
-  LDI %reg, #IMM /* Load immediate. */
-  ADDI %reg, %reg, #IMM /* Add immediate */
-  SUBI %reg, %reg, #IMM /* Subtract immediate */
-  MULI %reg, %reg, #IMM /* Multiply immediate */
-  DIVI %reg, %reg, #IMM /* Divide immediate */
-  MODI %reg, %reg, #IMM /* Modulus immediate */
-  SHLI %reg, %reg, #IMM /* Shift left immediate */
-  SHRI %reg, %reg, #IMM /* Shift right immediate */
-  ANDI %reg, %reg, #IMM /* And immediate */
-  ORI %reg, %reg, #IMM /* Or immediate */
-  XORI %reg, %reg, #IMM /* Xor immediate */
-
-Register Integer Arithmetic/Logic
----------------------------------
-
-  ADD %reg, %reg, %reg /* Add */
-  SUB %reg, %reg, %reg /* Subtract */
-  MUL %reg, %reg, %reg /* Multiply */
-  DIV %reg, %reg, %reg /* Divide */
-  MOD %reg, %reg, %reg /* Modulus */
-  SHL %reg, %reg, %reg /* Shift left */
-  SHR %reg, %reg, %reg /* Shift right */
-  AND %reg, %reg, %reg /* Bitwise and */
-  OR %reg, %reg, %reg /* Bitwise or */
-  XOR %reg, %reg, %reg /* Bitwise xor */
-  NEG %reg, %reg /* Negate */
-  NOT %reg, %reg /* Bitwise invert */
-
-Floating Point Arithmetic
--------------------------
-
-  ITOF %reg, %reg       /* Integer to floating point. */
-  FTOI %reg, %reg       /* Floating point to integer, truncate. */
-  FNEG %reg, %reg       /* Negate floating point number. */
-  FADD %reg, %reg, %reg /* Add, full precision. */
-  FSUB %reg, %reg, %reg /* Subtract, full precision. */
-  FMUL %reg, %reg, %reg /* Multiply, full precision. */ 
-  FDIV %reg, %reg, %reg /* Divide, full precision. */
-
-Control Flow
-------------
-
-  JMPI #IMM       /* Jump to immediate */
-  JMPR %reg       /* Jump indirect (to register) */
-  JALI %reg, #IMM /* Jump and link immediate */
-  JALR %reg, %reg /* Jump and link indirect */
-
-SIMD Control
-------------
-
-  CLONE %reg /* Clone register state in to thread %reg */
-  JALIS %reg, %rN, #IMM /* Jump and link immediate, spawning cloned threads. */
-  JALRS %rL, %rL, %rN /* Jump and link indirect, spawning clowned threads. */
-  JMPRT %reg  /* Jump to register, terminating cloned threads. */
-
-Other
------
