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) - 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) - */ - - { - long result; - - insn = bfd_get_16 (abfd, address); - result = insn + addend; - -#define BIT15_SET(x) ((x) & 0x8000) -#define OVERFLOWS(a,i) ((((a) & 0xffff) + (i)) > 0xffff) - - if ((BIT15_SET (result) && !
