The r_offset field of the - R_SH_USES reloc is the PC relative offset to the instruction which - loads the register (the r_offset field is computed as though it - were a jump instruction, so the offset value is actually from four - bytes past the instruction). The linker can use this reloc to - determine just which function is being called, and thus decide - whether it is possible to replace the jsr with a bsr. - - If multiple function calls are all based on a single register load - (i.e., the same function is called multiple times), the compiler - guarantees that each function call will have an R_SH_USES reloc. - Therefore, if the linker is able to convert each R_SH_USES reloc - which refers to that address, it can safely eliminate the register - load. - - When the assembler creates an R_SH_USES reloc, it examines it to - determine which address is being loaded (L1 in the above example). - It then counts the number of references to that address, and - creates an R_SH_COUNT reloc at that address. The r_offset field of - the R_SH_COUNT reloc will be the number of references. If the - linker is able to eliminate a register load, it can use the - R_SH_COUNT reloc to see whether it can also eliminate the function - address. - - SH relaxing also handles another, unrelated, matter. On the SH, if - a load or store instruction is not aligned on a four byte boundary, - the memory cycle interferes with the 32 bit instruction fetch, - causing a one cycle bubble in the pipeline.
