3763 Section names that look like .mips16.fn.FNNAME contain stubs that
3764 copy floating point arguments from the fp regs to the gp regs and
3765 then jump to FNNAME. If any 32 bit function calls FNNAME, the
3766 call should be redirected to the stub instead. If no 32 bit
3767 function calls FNNAME, the stub should be discarded. We need to
3768 consider any reference to the function, not just a call, because
3769 if the address of the function is taken we will need the stub,
3770 since the address might be passed to a 32 bit function.
3772 Section names that look like .mips16.call.FNNAME contain stubs
3773 that copy floating point arguments from the gp regs to the fp
3774 regs and then jump to FNNAME. If FNNAME is a 32 bit function,
3775 then any 16 bit function that calls FNNAME should be redirected
3776 to the stub instead. If FNNAME is not a 32 bit function, the
3777 stub should be discarded.
3779 .mips16.call.fp.FNNAME sections are similar, but contain stubs
3780 which call FNNAME and then copy the return value from the fp regs
3781 to the gp regs. These stubs store the return value in $18 while
3782 calling FNNAME; any function which might call one of these stubs
3783 must arrange to save $18 around the call. (This case is not
3784 needed for 32 bit functions that call 16 bit functions, because
3785 16 bit functions always return floating point values in both
3788 Note that in all cases FNNAME might be defined statically.
3789 Therefore, FNNAME is not used literally. Instead, the relocation
3790 information will indicate which symbol the section is for.

6490 ! JALX ! X! Imm 20:16 ! Imm 25:21 !

6495 JALX is the 5-bit value 00011. X is 0 for jal, 1 for jalx.
6496 Note that the immediate value in the first word is swapped.
6498 When producing a relocateable object file, R_MIPS16_26 is
6499 handled mostly like R_MIPS_26. In particular, the addend is
6500 stored as a straight 26-bit value in a 32-bit instruction.
6501 (gas makes life simpler for itself by never adjusting a
6502 R_MIPS16_26 reloc to be against a section, so the addend is
6503 always zero). However, the 32 bit instruction is stored as 2
6504 16-bit values, rather than a single 32-bit value. In a
6505 big-endian file, the result is the same; in a little-endian
6506 file, the two 16-bit halves of the 32 bit value are swapped.
6507 This is so that a disassembler can recognize the jal
6510 When doing a final link, R_MIPS16_26 is treated as a 32 bit
6511 instruction stored as two 16-bit values. The addend A is the
6512 contents of the targ26 field. The calculation is the same as
6513 R_MIPS_26. When storing the calculated value, reorder the
6514 immediate value as shown above, and don't forget to store the
6515 value as two 16-bit values.
6517 To put it in MIPS ABI terms, the relocation field is T-targ26-16,
