-/* The "-4" and "+4" offsets against _GLOBAL_OFFSET_TABLE_ are
- critical since they represent the offset from the thunk call to the
- instruction containing the _GLOBAL_OFFSET_TABLE_ reference.
- Therefore these instructions cannot be moved around without
- appropriate adjustments to those offsets.
-
- Furthermore, these expressions are special in another regard. When
- the assembler sees a reference to _GLOBAL_OFFSET_TABLE_ inside of
- a %hi() or %lo(), it emits a PC-relative relocation. This causes
- R_SPARC_HI22 to turn into R_SPARC_PC22, and R_SPARC_LO10 to turn into
- R_SPARC_PC10, respectively.
-
- Even when v9 we use a call sequence instead of using "rd %pc" because
- RDPC is extremely expensive and incurs a full pipeline flush. */
