|
* Simple SPARC relocations for the benefit of self-relocation of ld.so
|
|
|
|
|
* avoiding the use of global variables (ie. reloc_bitshift[] et. al.).
|
|
|
|
|
* Only types supported are RELOC_32 and RELOC_RELATIVE.
|
|
|
|
|
*
|
|
|
|
|
* This *must* be a static function, so it is not called through a jmpslot.
