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