+
+ 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.
+
