  /* The mips16 compiler uses a couple of special sections to handle
     floating point arguments.

     Section names that look like .mips16.fn.FNNAME contain stubs that
     copy floating point arguments from the fp regs to the gp regs and
     then jump to FNNAME.  If any 32 bit function calls FNNAME, the
     call should be redirected to the stub instead.  If no 32 bit
     function calls FNNAME, the stub should be discarded.  We need to
     consider any reference to the function, not just a call, because
     if the address of the function is taken we will need the stub,
     since the address might be passed to a 32 bit function.

     Section names that look like .mips16.call.FNNAME contain stubs
     that copy floating point arguments from the gp regs to the fp
     regs and then jump to FNNAME.  If FNNAME is a 32 bit function,
     then any 16 bit function that calls FNNAME should be redirected
     to the stub instead.  If FNNAME is not a 32 bit function, the
     stub should be discarded.

     .mips16.call.fp.FNNAME sections are similar, but contain stubs
     which call FNNAME and then copy the return value from the fp regs
     to the gp regs.  These stubs store the return value in $18 while
     calling FNNAME; any function which might call one of these stubs
     must arrange to save $18 around the call.  (This case is not
     needed for 32 bit functions that call 16 bit functions, because
     16 bit functions always return floating point values in both
     $f0/$f1 and $2/$3.)

     Note that in all cases FNNAME might be defined statically.
     Therefore, FNNAME is not used literally.  Instead, the relocation
     information will indicate which symbol the section is for.

     We record any stubs that we find in the symbol table.  */

	 When producing a relocateable object file, R_MIPS16_26 is
	 handled mostly like R_MIPS_26.  In particular, the addend is
	 stored as a straight 26-bit value in a 32-bit instruction.
	 (gas makes life simpler for itself by never adjusting a
	 R_MIPS16_26 reloc to be against a section, so the addend is
	 always zero).  However, the 32 bit instruction is stored as 2
	 16-bit values, rather than a single 32-bit value.  In a
	 big-endian file, the result is the same; in a little-endian
	 file, the two 16-bit halves of the 32 bit value are swapped.
	 This is so that a disassembler can recognize the jal
	 instruction.

	 When doing a final link, R_MIPS16_26 is treated as a 32 bit
	 instruction stored as two 16-bit values.  The addend A is the
	 contents of the targ26 field.  The calculation is the same as
	 R_MIPS_26.  When storing the calculated value, reorder the
	 immediate value as shown above, and don't forget to store the
	 value as two 16-bit values.

	 To put it in MIPS ABI terms, the relocation field is T-targ26-16,
	 defined as

	 big-endian:
	 +--------+----------------------+
	 |        |                      |
	 |        |    targ26-16         |
	 |31    26|25                   0|
	 +--------+----------------------+

	 little-endian:
	 +----------+------+-------------+
	 |          |      |             |
	 |  sub1    |      |     sub2    |
	 |0        9|10  15|16         31|
	 +----------+--------------------+
	 where targ26-16 is sub1 followed by sub2 (i.e., the addend field A is
	 ((sub1 << 16) | sub2)).

	 When producing a relocateable object file, the calculation is
	 (((A < 2) | ((P + 4) & 0xf0000000) + S) >> 2)
	 When producing a fully linked file, the calculation is
	 let R = (((A < 2) | ((P + 4) & 0xf0000000) + S) >> 2)
	 ((R & 0x1f0000) << 5) | ((R & 0x3e00000) >> 5) | (R & 0xffff)  */

	/* Shuffle the bits according to the formula above.  */
