653 | ||
654 | movl L1,r0 | |
655 | ... | |
656 | jsr @r0 | |
657 | ... | |
658 | L1: | |
659 | .long function | |
660 | ||
661 | The compiler and assembler will cooperate to create R_SH_USES | |
662 | relocs on the jsr instructions. The r_offset field of the | |
663 | R_SH_USES reloc is the PC relative offset to the instruction which | |
664 | loads the register (the r_offset field is computed as though it | |
665 | were a jump instruction, so the offset value is actually from four | |
666 | bytes past the instruction). The linker can use this reloc to | |
667 | determine just which function is being called, and thus decide | |
668 | whether it is possible to replace the jsr with a bsr. | |
669 | ||
670 | If multiple function calls are all based on a single register load | |
671 | (i.e., the same function is called multiple times), the compiler | |
672 | guarantees that each function call will have an R_SH_USES reloc. | |
673 | Therefore, if the linker is able to convert each R_SH_USES reloc | |
674 | which refers to that address, it can safely eliminate the register | |
675 | load. | |
676 | ||
677 | When the assembler creates an R_SH_USES reloc, it examines it to | |
678 | determine which address is being loaded (L1 in the above example). | |
679 | It then counts the number of references to that address, and | |
680 | creates an R_SH_COUNT reloc at that address. The r_offset field of | |
681 | the R_SH_COUNT reloc will be the number of references. If the | |
682 | linker is able to eliminate a register load, it can use the | |
683 | R_SH_COUNT reloc to see whether it can also eliminate the function | |
684 | address. | |
685 | ||
686 | SH relaxing also handles another, unrelated, matter. On the SH, if | |
687 | a load or store instruction is not aligned on a four byte boundary, | |
688 | the memory cycle interferes with the 32 bit instruction fetch, | |
689 | causing a one cycle bubble in the pipeline. Therefore, we try to | |
690 | align load and store instructions on four byte boundaries if we | |
691 | can, by swapping them with one of the adjacent instructions. */ | |
