- at least one R_68K_GOT16O relocation and no R_68K_GOT8O relocations.
+ * R_16 type is used in entries for symbols that have at least one
+ R_68K_GOT16O or R_68K_TLS_*16 relocation and no R_8 relocations.
We can have at most 0x4000 such entries in one GOT.
- * R_68K_GOT32O type is used in all other cases. We can have as many
- such entries in one GOT as we like.
+ * R_32 type is used in all other cases. We can have as many
+ such entries in one GOT as we'd like.
When counting relocations we have to include the count of the smaller
ranged relocations in the counts of the larger ranged ones in order
to correctly detect overflow.
Sorting the GOT: In each GOT starting offsets are assigned to
- R_68K_GOT8O entries, which are followed by R_68K_GOT16O entries, and
- R_68K_GOT32O entries go at the end. See finalize_got_offsets for details.
+ R_8 entries, which are followed by R_16 entries, and
+ R_32 entries go at the end. See finalize_got_offsets for details.
Negative GOT offsets: To double usable offset range of GOTs we use
negative offsets. As we assign entries with GOT offsets relative to
/* Initialize GOT. */
