- 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

- Most mips16 instructions are 16 bits, but these instructions
- are 32 bits.
-
- The format of these instructions is:
-
- +--------------+--------------------------------+
- ! 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 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) */

- are 32 bits.
-

-
- +--------------+--------------------------------+
- ! 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 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) */
