+
+ +--------------+--------------------------------+
+ ! JALX ! X! Imm 20:16 ! Imm 25:21 !
+ +--------------+--------------------------------+
+ ! Immediate 15:0 !
+ +-----------------------------------------------+
+
+ JALX is the 5-bit value 00011. X is 0 for jal, 1 for jalx.
+ Note that the immediate value in the first word is swapped.
+
+ When producing a relocatable 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|
+ +--------+----------------------+
+

+ +----------+------+-------------+
+ | | | |
+ | 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 relocatable 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) */
