+
+ The assembler has already done some of this: If the value stored in
+ the instruction has its 15th bit set, (counting from zero) then the
+ assembler will have added 1 to the value stored in the associated
+ HI16S reloc. So for example, these relocations:
+
+ movhi hi( fred ), r0, r1
+ movea lo( fred ), r1, r1
+
+ will store 0 in the value fields for the MOVHI and MOVEA instructions
+ and addend will be the address of fred, but for these instructions:
+
+ movhi hi( fred + 0x123456), r0, r1
+ movea lo( fred + 0x123456), r1, r1
+
+ the value stored in the MOVHI instruction will be 0x12 and the value
+ stored in the MOVEA instruction will be 0x3456. If however the
+ instructions were:
+
+ movhi hi( fred + 0x10ffff), r0, r1
+ movea lo( fred + 0x10ffff), r1, r1
+
+ then the value stored in the MOVHI instruction would be 0x11 (not
+ 0x10) and the value stored in the MOVEA instruction would be 0xffff.
+ Thus (assuming for the moment that the addend is 0), at run time the
+ MOVHI instruction loads 0x110000 into r1, then the MOVEA instruction
+ adds 0xffffffff (sign extension!) producing 0x10ffff. Similarly if
+ the instructions were:
+
+ movhi hi( fred - 1), r0, r1
+ movea lo( fred - 1), r1, r1
+
+ then 0 is stored in the MOVHI instruction and -1 is stored in the
+ MOVEA instruction.
+
+ Overflow can occur if the addition of the value stored in the
+ instruction plus the addend sets the 15th bit when before it was clear.
+ This is because the 15th bit will be sign extended into the high part,
+ thus reducing its value by one, but since the 15th bit was originally
+ clear, the assembler will not have added 1 to the previous HI16S reloc
+ to compensate for this effect. For example:
+
+ movhi hi( fred + 0x123456), r0, r1
+ movea lo( fred + 0x123456), r1, r1
+
+ The value stored in HI16S reloc is 0x12, the value stored in the LO16
+ reloc is 0x3456. If we assume that the address of fred is 0x00007000
+ then the relocations become:
+
+ HI16S: 0x0012 + (0x00007000 >> 16) = 0x12
+ LO16: 0x3456 + (0x00007000 & 0xffff) = 0xa456
+
+ but when the instructions are executed, the MOVEA instruction's value
+ is signed extended, so the sum becomes:
+
+ 0x00120000
+ + 0xffffa456
+ ------------
+ 0x0011a456 but 'fred + 0x123456' = 0x0012a456
+
+ Note that if the 15th bit was set in the value stored in the LO16
+ reloc, then we do not have to do anything:
+
+ movhi hi( fred + 0x10ffff), r0, r1
+ movea lo( fred + 0x10ffff), r1, r1
+
+ HI16S: 0x0011 + (0x00007000 >> 16) = 0x11
+ LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff
+
+ 0x00110000
+ + 0x00006fff
+ ------------
+ 0x00116fff = fred + 0x10ffff = 0x7000 + 0x10ffff
+
+ Overflow can also occur if the computation carries into the 16th bit
+ and it also results in the 15th bit having the same value as the 15th
+ bit of the original value. What happens is that the HI16S reloc
+ will have already examined the 15th bit of the original value and
+ added 1 to the high part if the bit is set. This compensates for the
+ sign extension of 15th bit of the result of the computation. But now
+ there is a carry into the 16th bit, and this has not been allowed for.
+
+ So, for example if fred is at address 0xf000:
+
+ movhi hi( fred + 0xffff), r0, r1 [bit 15 of the offset is set]
+ movea lo( fred + 0xffff), r1, r1
+
+ HI16S: 0x0001 + (0x0000f000 >> 16) = 0x0001
+ LO16: 0xffff + (0x0000f000 & 0xffff) = 0xefff (carry into bit 16 is lost)
+
+ 0x00010000
+ + 0xffffefff
+ ------------
+ 0x0000efff but 'fred + 0xffff' = 0x0001efff
+
+ Similarly, if the 15th bit remains clear, but overflow occurs into
+ the 16th bit then (assuming the address of fred is 0xf000):
+
+ movhi hi( fred + 0x7000), r0, r1 [bit 15 of the offset is clear]
+ movea lo( fred + 0x7000), r1, r1
+
+ HI16S: 0x0000 + (0x0000f000 >> 16) = 0x0000
+ LO16: 0x7000 + (0x0000f000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
+
+ 0x00000000
+ + 0x00006fff
+ ------------
+ 0x00006fff but 'fred + 0x7000' = 0x00016fff
+
+ Note - there is no need to change anything if a carry occurs, and the
+ 15th bit changes its value from being set to being clear, as the HI16S
+ reloc will have already added in 1 to the high part for us:
+
+ movhi hi( fred + 0xffff), r0, r1 [bit 15 of the offset is set]
+ movea lo( fred + 0xffff), r1, r1
+
+ HI16S: 0x0001 + (0x00007000 >> 16)

+
+ 0x00010000
+ + 0x00006fff (bit 15 not set, so the top half is zero)
