/* FIXME: x32 is very strange in its use of 64-bit relocation types in
|
|
* a 32-bit environment. As long as the memory at reloc_addr is
|
|
* zero-filled prior to relocations, just treating 64-bit relocations
|
|
* as operating on 32-bit slots should be fine, but this should be
|
|
* checked. In particular, R_X86_64_64, R_X86_64_DTPOFF64, and
|
|
* R_X86_64_TPOFF64 may need checking. */

/* The R_X86_64_64, R_X86_64_DTPOFF32, and R_X86_64_TPOFF32 reloc types
|
|
* were previously mapped in the switch table form of this file; however,
|
|
* they do not seem to be used/usable for anything. If needed, new
|
|
* mappings will have to be added. */
