case R_V850_LO16:
/* Calculate the sum of the value stored in the instruction and the
addend and check for overflow from the low 16 bits into the high
16 bits. 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
1999-05-03 09:29:11 +02:00
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)
LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
0x00010000
+ 0x00006fff (bit 15 not set, so the top half is zero)
------------
0x00016fff which is right (assuming that fred is at 0x7000)
but if the 15th bit goes from being clear to being set, then we must
once again handle overflow:
movhi hi( fred + 0x7000), r0, r1 [bit 15 of the offset is clear]
movea lo( fred + 0x7000), r1, r1
HI16S: 0x0000 + (0x0000ffff >> 16)
LO16: 0x7000 + (0x0000ffff & 0xffff) = 0x6fff (carry into bit 16)
0x00000000
+ 0x00006fff (bit 15 not set, so the top half is zero)
------------
0x00006fff which is wrong (assuming that fred is at 0xffff). */
