7623 | * obtain the absolute address of the GOT, and it is strongly | |
7624 | * preferable from a performance point of view to avoid using | |
7625 | * a runtime relocation for this. The actual sequence of | |
7626 | * instructions often look something like: | |
7627 | * | |
7628 | * call .L66 | |
7629 | * .L66: | |
7630 | * popl %ebx | |
7631 | * addl $_GLOBAL_OFFSET_TABLE_+[.-.L66],%ebx | |
7632 | * | |
7633 | * The call and pop essentially return the absolute address | |
7634 | * of the label .L66 and store it in %ebx. The linker itself | |
7635 | * will ultimately change the first operand of the addl so | |
7636 | * that %ebx points to the GOT, but to keep things simple, the | |
7637 | * .o file must have this operand set so that it generates not | |
7638 | * the absolute address of .L66, but the absolute address of | |
7639 | * itself. This allows the linker itself simply treat a GOTPC | |
7640 | * relocation as asking for a pcrel offset to the GOT to be | |
7641 | * added in, and the addend of the relocation is stored in the | |
7642 | * operand field for the instruction itself. | |
7643 | * | |
7644 | * Our job here is to fix the operand so that it would add | |
7645 | * the correct offset so that %ebx would point to itself. The | |
7646 | * thing that is tricky is that .-.L66 will point to the | |
7647 | * beginning of the instruction, so we need to further modify | |
7648 | * the operand so that it will point to itself. There are | |
7649 | * other cases where you have something like: | |
7650 | * | |
7651 | * .long $_GLOBAL_OFFSET_TABLE_+[.-.L66] | |
7652 | * | |
7653 | * and here no correction would be required. Internally in | |
7654 | * the assembler we treat operands of this form as not being | |
7655 | * pcrel since the '.' is explicitly mentioned, and I wonder | |
7656 | * whether it would simplify matters to do it this way. Who | |
7657 | * knows. In earlier versions of the PIC patches, the | |
7658 | * pcrel_adjust field was used to store the correction, but | |
7659 | * since the expression is not pcrel, I felt it would be | |
7660 | * confusing to do it this way. */ | |
