| operand value in *INSN and return true on success. |
| |
| 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). */ |
