/* 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. */
