9623 | * have operands that look like | |
9624 | * "_GLOBAL_OFFSET_TABLE_+[.-.L284]". The goal here is to | |
9625 | * obtain the absolute address of the GOT, and it is strongly | |
9626 | * preferable from a performance point of view to avoid using | |
9627 | * a runtime relocation for this. The actual sequence of | |
9628 | * instructions often look something like: | |
9629 | * | |
9630 | * call .L66 | |
9631 | * .L66: | |
9632 | * popl %ebx | |
9633 | * addl $_GLOBAL_OFFSET_TABLE_+[.-.L66],%ebx | |
9634 | * | |
9635 | * The call and pop essentially return the absolute address | |
9636 | * of the label .L66 and store it in %ebx. The linker itself | |
9637 | * will ultimately change the first operand of the addl so | |
9638 | * that %ebx points to the GOT, but to keep things simple, the | |
9639 | * .o file must have this operand set so that it generates not | |
9640 | * the absolute address of .L66, but the absolute address of | |
9641 | * itself. This allows the linker itself simply treat a GOTPC | |
9642 | * relocation as asking for a pcrel offset to the GOT to be | |
9643 | * added in, and the addend of the relocation is stored in the | |
9644 | * operand field for the instruction itself. | |
9645 | * | |
9646 | * Our job here is to fix the operand so that it would add | |
9647 | * the correct offset so that %ebx would point to itself. The | |
9648 | * thing that is tricky is that .-.L66 will point to the | |
9649 | * beginning of the instruction, so we need to further modify | |
9650 | * the operand so that it will point to itself. There are | |
9651 | * other cases where you have something like: | |
9652 | * | |
9653 | * .long $_GLOBAL_OFFSET_TABLE_+[.-.L66] | |
9654 | * | |
9655 | * and here no correction would be required. Internally in | |
9656 | * the assembler we treat operands of this form as not being | |
9657 | * pcrel since the '.' is explicitly mentioned, and I wonder | |
9658 | * whether it would simplify matters to do it this way. Who | |
9659 | * knows. In earlier versions of the PIC patches, the | |
9660 | * pcrel_adjust field was used to store the correction, but | |
9661 | * since the expression is not pcrel, I felt it would be | |
9662 | * confusing to do it this way. */ | |
