8521 | * have operands that look like | |
8522 | * "_GLOBAL_OFFSET_TABLE_+[.-.L284]". The goal here is to | |
8523 | * obtain the absolute address of the GOT, and it is strongly | |
8524 | * preferable from a performance point of view to avoid using | |
8525 | * a runtime relocation for this. The actual sequence of | |
8526 | * instructions often look something like: | |
8527 | * | |
8528 | * call .L66 | |
8529 | * .L66: | |
8530 | * popl %ebx | |
8531 | * addl $_GLOBAL_OFFSET_TABLE_+[.-.L66],%ebx | |
8532 | * | |
8533 | * The call and pop essentially return the absolute address | |
8534 | * of the label .L66 and store it in %ebx. The linker itself | |
8535 | * will ultimately change the first operand of the addl so | |
8536 | * that %ebx points to the GOT, but to keep things simple, the | |
8537 | * .o file must have this operand set so that it generates not | |
8538 | * the absolute address of .L66, but the absolute address of | |
8539 | * itself. This allows the linker itself simply treat a GOTPC | |
8540 | * relocation as asking for a pcrel offset to the GOT to be | |
8541 | * added in, and the addend of the relocation is stored in the | |
8542 | * operand field for the instruction itself. | |
8543 | * | |
8544 | * Our job here is to fix the operand so that it would add | |
8545 | * the correct offset so that %ebx would point to itself. The | |
8546 | * thing that is tricky is that .-.L66 will point to the | |
8547 | * beginning of the instruction, so we need to further modify | |
8548 | * the operand so that it will point to itself. There are | |
8549 | * other cases where you have something like: | |
8550 | * | |
8551 | * .long $_GLOBAL_OFFSET_TABLE_+[.-.L66] | |
8552 | * | |
8553 | * and here no correction would be required. Internally in | |
8554 | * the assembler we treat operands of this form as not being | |
8555 | * pcrel since the '.' is explicitly mentioned, and I wonder | |
8556 | * whether it would simplify matters to do it this way. Who | |
8557 | * knows. In earlier versions of the PIC patches, the | |
8558 | * pcrel_adjust field was used to store the correction, but | |
8559 | * since the expression is not pcrel, I felt it would be | |
8560 | * confusing to do it this way. */ | |
