7698 | /* HOW DIFF RELOCATION WORKS. | |
7699 | ||
7700 | First of all, this relocation is used to calculate the distance | |
7701 | between two symbols in the SAME section. It is used for jump- | |
7702 | table, debug information, exception table, et al. Therefore, | |
7703 | it is a unsigned positive value. It is NOT used for general- | |
7704 | purpose arithmetic. | |
7705 | ||
7706 | Consider this example, the distance between .LEND and .LBEGIN | |
7707 | is stored at the address of foo. | |
7708 | ||
7709 | ---- >8 ---- >8 ---- >8 ---- >8 ---- | |
7710 | .data | |
7711 | foo: | |
7712 | .word .LBEGIN - .LEND | |
7713 | ||
7714 | .text | |
7715 | [before] | |
7716 | .LBEGIN | |
7717 | \ | |
7718 | [between] distance | |
7719 | / | |
7720 | .LEND | |
7721 | [after] | |
7722 | ---- 8< ---- 8< ---- 8< ---- 8< ---- | |
7723 | ||
7724 | We use a single relocation entry for this expression. | |
33eaf5de | 7725 | * The initial distance value is stored directly in that location |
35c08157 KLC |
7726 | specified by r_offset (i.e., foo in this example.) |
7727 | * The begin of the region, i.e., .LBEGIN, is specified by | |
7728 | r_info/R_SYM and r_addend, e.g., .text + 0x32. | |
7729 | * The end of region, i.e., .LEND, is represented by | |
7730 | .LBEGIN + distance instead of .LEND, so we only need | |
7731 | a single relocation entry instead of two. | |
7732 | ||
7733 | When an instruction is relaxed, we adjust the relocation entry | |
7734 | depending on where the instruction locates. There are three | |
7735 | cases, before, after and between the region. | |
7736 | * between: Distance value is read from r_offset, adjusted and | |
7737 | written back into r_offset. | |
7738 | * before: Only r_addend is adjust. | |
7739 | * after: We don't care about it. | |
7740 | ||
7741 | Hereby, there are some limitation. | |
7742 | ||
7743 | `(.LEND - 1) - .LBEGIN' and `(.LEND - .LBEGIN) - 1' | |
7744 | are semantically different, and we cannot handle latter case | |
7745 | when relaxation. | |
7746 | ||
7747 | The latter expression means subtracting 1 from the distance | |
7748 | between .LEND and .LBEGIN. And the former expression means | |
7749 | the distance between (.LEND - 1) and .LBEGIN. | |
7750 | ||
7751 | The nuance affects whether to adjust distance value when relax | |
7752 | an instruction. In another words, whether the instruction | |
7753 | locates in the region. Because we use a single relocation entry, | |
7754 | there is no field left for .LEND and the subtrahend. | |
7755 | ||
7756 | Since GCC-4.5, GCC may produce debug information in such expression | |
7757 | .long .L1-1-.L0 | |
7758 | in order to describe register clobbering during an function-call. | |
7759 | .L0: | |
7760 | call foo | |
