+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. */

+
+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. */
