-/* This function handles relaxing on the SH.
-
- Function calls on the SH look like this:
-
- movl L1,r0
- ...
- jsr @r0
- ...
- L1:
- .long function
-
- The compiler and assembler will cooperate to create R_SH_USES
- relocs on the jsr instructions. 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. Therefore, we try to
- align load and store instructions on four byte boundaries if we
- can, by swapping them with one of the adjacent instructions. */
