+@cindex opcodes for V850
+@code{@value{AS}} implements all the standard V850 opcodes.
+
+@code{@value{AS}} also implements the following pseudo ops:
+
+@table @code
+
+@cindex @code{hi} pseudo-op, V850
+@item hi()
+Computes the higher 16 bits of the given expression and stores it into
+the immediate operand field of the given instruction. For example:
+
+ @samp{mulhi hi(here - there), r5, r6}
+
+computes the difference between the address of labels 'here' and
+'there', takes the upper 16 bits of this difference, shifts it down 16
+bits and then mutliplies it by the lower 16 bits in register 5, putting
+the result into register 6.
+
+
+@cindex @code{lo} pseudo-op, V850
+@item lo()
+Computes the lower 16 bits of the given expression and stores it into
+the immediate operand field of the given instruction. For example:
+
+ @samp{addi lo(here - there), r5, r6}
+
+computes the difference between the address of labels 'here' and
+'there', takes the lower 16 bits of this difference and adds it to
+register 5, putting the result into register 6.
+
+@cindex @code{sdaoff} pseudo-op, V850
+@item sdaoff()
+Computes the offset of the named variable from the start of the Small
+Data Area (whoes address is held in register 4, the GP register) and
+stores the result as a 16 bit signed value in the immediate operand
+field of the given instruction. For example:
+
+ @samp{ld.w sdaoff(_a_variable)[gp],r6}
+
+loads the contents of the location pointed to by the label '_a_variable'
+into register 6, provided that the label is located somewhere within +/-
+32K of the address held in the GP register. [Note the linker assumes
+that the GP register contains a fixed address set to the address of the
+label called '__gp'].
+
+@cindex @code{tdaoff} pseudo-op, V850
+@item tdaoff()
+Computes the offset of the named variable from the start of the Tiny
+Data Area (whoes address is held in register 30, the EP register) and
+stores the result as a 4,5,7 or 8 bit unsigned value in the immediate
+operand field of the given instruction. For example:
+
+ @samp{sld.w tdaoff(_a_variable)[ep],r6}
+
+loads the contents of the location pointed to by the label '_a_variable'
+into register 6, provided that the label is located somewhere within 256
+bytes of the address held in the EP register. [Note the linker assumes
+that the EP register contains a fixed address set to the address of the
+label called '--ep'].
+
+@cindex @code{zdaoff} pseudo-op, V850
+@item zdaoff()
+Computes the offset of the named variable from address 0 and stores the
+result as a 16 bit signed value in the immediate operand field of the
+given instruction. For example:
+
+ @samp{movea zdaoff(_a_variable),zero,r6}
+
+puts the address of the label '_a_variable' into register 6, assuming
+that the label is somewhere within the first 32K of memory.
