+ hardwired to zero.
+
+ When one of these entries is executed, it winds up calling into
+ ld.so. ld.so looks at the reloc number, available via the return
+ address, to determine which entry this is. It then looks at the
+ reloc and patches up the entry in the table into a sethi and jmp
+ to the real address followed by a nop. This means that the reloc

+
+ Each entry in the hash table is eight bytes. The first four
+ bytes are a symbol index into the dynamic symbols. The second
+ four bytes are the index of the next hash table entry in the

+ The first B entries in the hash table each start a bucket which
